2017’s Top Newsmaker: Deere buys Wirtgen

Released during the sale announcement, this graphic shows how the Deere and Wirtgen brands will be integrated on the jobsite to provide a full line of construction and roadbuilding equipment. (Note: Wirtgen crushers and screeners are also part of quarry operations.)

After identifying Wirtgen as an attractive strategic fit several years ago, John Deere pulled the trigger in a surprise move this June, buying German equipment manufacturer Wirtgen Group. The all-cash $5.2 billion deal gave Deere access to Wirtgen’s deep roots in roadbuilding and quarry equipment markets. The deal also made Deere the first manufacturer to offer crushing and screening as well as mobile equipment. In the acquisition announcement, Deere said it would maintain Wirtgen’s brands – Hamm, Vogele, Wirtgen, Kleeman and Benninghoven – along with its manufacturing footprint, employees and distribution network.

Cat shocks Peoria

New Caterpillar global HQ and campus

What will never be: The Cat Peoria headquarters building announced in 2015.

The 107-year intertwining of Caterpillar and Peoria, Illinois, suffered a break in January when the company announced it would relocate its headquarters to the Chicago area. The move – involving about 300 executives and support personnel – put a definite end to the announced downtown three-tower headquarters riverfront complex, announced in 2015.

Atlas Copco’s busy January

Dynapac sports a new look after Fayat purchase.

January was a busy month for Atlas Copco last year. It announced it was selling its Dynapac line of pavers, planers and rollers to Fayat Group, parent of Bomag. Then the board proposed separating out its Mining and Rock Excavation Technique Business Area and its Construction Tools Division to create a new company dedicated to mining and civil engineering customers. The new company, eventually called Epiroc, is expected to be listed on the Nasdaq Stockholm stock exchange in mid-2018. Atlas Copco will retain its air compressor and vacuum businesses.


Rental continues to soar

HercRentals, H&E Equipment Services and United Rentals all reported strong third quarters, serving to underscore the American Rental Association’s forecast that construction/industrial equipment rental revenue would grow at a compounded annual growth rate of 4.1 percent between 2017 and 2021, to $40.4 billion.

United Rentals buying spree

United Rentals upped the ante in August for Neff Corporation, offering almost $4 per share more than suitor H&E Equipment Service and snagged the deal. It was the second big acquisition for United Rentals, which spent $965 million for NES Rental Holdings in April. Also, in August, United bought Cummins’ mobile rental generator fleet.


The 2017 Timeline (continues throughout)

Our feet are still hurting

ConExpo, the industry’s every-third-year extravaganza, featured an all new Tech Experience with a showstopper 3D-printed compact excavator. Show stats reflected sunny skies and moods: 128,000 attendees, plus a record-breaking 2,800 exhibitors and 2.8 million net square feet of exhibits.

Data and more data

The big story in the heavy equipment industry continues to be all about data. Specifically, the data coming off your machine’s telematics and how that data can become a key part of your overall jobsite management picture, not to mention a manufacturer’s profit statement. Cat, for one, has been direct about its intentions on this front. “Instead of Cat being a brand on the jobsite, we’re pushing to make it the jobsite brand,” said Cat’s Paolo Fellin at ConExpo.

Parts, parts and more parts

John Deere, JLG and Volvo used ConExpo to announce new parts initiatives. Deere’s Big Part Promise guarantees critical parts by the end of the business day, or they’re free. JLG’s MaxQuip parts line supplies users with competitive model parts, and Volvo’s 24-Hour Parts Guarantee ensures delivery of parts within 24 hours of the order. In November, Cat launched its Yellowmark aftermarket brand, aimed at customers looking for lower-cost parts, particularly for older equipment.

Silica dust rules arrive

DD 250, Diamond coring tool

After years of discussions, appeals and delays, the U.S. Occupational Safety and Health Administration began enforcing its new rules designed to reduce the amount of crystalline silica dust on construction worksites by 80 percent, on average, per 8-hour work shift. The rules were scheduled to take effect in June but were delayed until September 23rd for OSHA to fine-tune compliance guidelines. The goal is to reduce and prevent lung cancer, silicosis and other respiratory ailments caused by overexposure to crystalline silica, a common chemical compound found in rock, concrete and brick.

Georgia opens interstate bridge in 45 days

Facing catastrophic traffic snarls after an I-85 bridge in Atlanta was destroyed by fire, Georgia and federal transportation officials smoothed the engineering and regulatory path for contractor C. W. Matthews to complete a replacement overpass more than a month ahead of time. In addition to being a showcase for Accelerated Bridge Construction methods, the incident prompted state DOTs across the nation to assess their current under-bridge material storage practices.


Cat changes nomenclature

Further details on Cat’s nomenclature changes emerged in 2017. The letter modifiers on most Cat models will be dropped and replaced with a Build Number – which will only appear on product information, not on the machine itself – as generational changes occur. The first machine to use this new approach was the 745 articulated truck, which Cat debuted at ConExpo. One exception: Cat’s dozers, which will continue with their current E, K, N and T letter designations.


AWPs become MEWPs

Can’t say we’re fond of the new acronym, but as part of proposed aerial work platform standards, the name of the entire equipment category will be changed to “mobile elevating work platforms.” More important, these standards are leading to major changes to the machines, how rental shops deal with their customers and how contractors plan projects.

Texas takes a bullet train

A company called Texas Central announced plans to move forward on a bullet train that would link Houston and Dallas, a span of about 240 miles. According to the company, the train will be privately funded and return $2.5 billion in tax revenue back to the state. Fluor, Lane Construction and WSP (formerly Parsons Brinckerhoff) have been selected for design engineering. The train is anticipated to be operational in 2023.

Tech that’s here now…

…and tech that’s still to come

Some of these are far off, others are just around the corner.

ELDs become mandatory

Although there have been numerous attempts to postpone or rescind the electronic logging device mandate for on-highway trucks, as of press time, the Dec. 18, 2017, deadline was still in place. As detailed in a special report in our June issue, contractors can’t automatically assume they are exempt from these rules. In fact, using Randall-Reilly’s proprietary RigDig Business Intelligence database, we found more than 230,000 construction operations (contractors, material producers and equipment dealer/rental companies) are running more than 1 million trucks that could fall under the mandate.

Trending: How to get disaster work

With several states and one territory dealing with the aftermath of three massive hurricanes this year, our take on how to get disaster cleanup work received more than 36,000 page views. The aftermath of these disastrous storms gave construction contractors, subcontractors and workers plenty of debris cleanup and rebuilding work and was a contributing factor in construction unemployment reaching 4.5 percent in October, the lowest rate on record for that month, according to the Associated Builders and Contractors.

New market entries

Cat UTV

The story that wasn’t

For many, 2017 was going to be a year focused on America’s crumbling roads and bridges, with a new president in the White House who had pledged on the campaign trail a $3 trillion infrastructure plan. The Trump administration did not present a plan to Congress, and is still struggling to come up with ways to pay for it. Congress didn’t seem to mind the lack of a plan, as it spent the year mired in other issues, such as Obamacare, immigration, tax reform, the Russia investigation and claims of sexual harassment.

And in the meantime…

The American Society of Civil Engineers released its 2017 Infrastructure Report Card, and as a nation, we continued to get a solid overall D.

Cat’s legal woes

In March, Caterpillar’s Peoria, Illinois, corporate headquarters were raided by federal law enforcement officials as part of an investigation into the company’s tax strategy. The suit alleges the company avoided paying more than $2 billion in taxes by moving select profits to offshore shell companies located in Switzerland and Bermuda.

If that weren’t enough, the company is also under investigation by the International Trade Commission after German equipment maker Wirtgen (newly acquired by John Deere) filed a patent infringement complaint against Cat in August. Wirtgen alleges that Cat’s road milling machines violate its patents. In November, Cat fired back with a patent infringement complaint against Wirtgen concerning the same equipment.

Machine blends create show buzz

JCB Teleskid

Billed as a “half telescopic handler/half skid steer,” JCB’s Teleskid turned eyes at ConExpo and has created orders ever since, according to JCB. The machine – which also comes in a compact track loader version – can reach up to 13 feet, 3 inches and is the only skid steer that can dig below its chassis to a depth of 3 feet, says the company. Case Construction Equipment showed off its concept DL450 (aka the Minotaur) at the show, billed as a “compact dozer loader,” combining a compact track loader (CTL) with a dozer. The core feature of the DL450 is a C-frame dozer interface that pins directly into the machine chassis; it can be unpinned and disconnected like an attachment, turning the machine back into a standard CTL.

Chevy returns to medium-duty market

GM’s latest generation 6.6L Duramax V8 will power the coming Silverado 4500 and 5500 work trucks.

General Motors announced that the Chevy-branded medium-duty work trucks it has been developing in partnership with Navistar will be called the Silverado 4500 and Silverado 5500. The Silverados represent GM’s versions of the Class 4 and 5 vehicles.


Here are some quick takes on what our editors see ahead:

Don McLoud:

The Trump administration’s $1 trillion infrastructure plan will face a protracted funding battle in Congress, where members will have little interest in a fuel tax increase after just passing tax reform. Gridlock will prevent passage in 2018.

Tom Jackson:

Use of GPS/GNSS and telematics technology will see strong growth in 2018 as OEMs and software companies make their products more intuitive and easy to use. 2D and 3D automated digging with excavators will be the big winner.

Marcia Doyle:

The Internet of Things has exploded this year with tool makers Hilti and Milwaukee adding Wi-Fi capabilities to track tools and manage use. And now DeWalt is offering Wi-Fi boosters to create Wi-Fi ability beyond the jobsite trailer. As the information demands of jobsites increase, and as 5G comes on board, look for more companies to piggyback their jobsite presence – be it a toolbox, hand tool or machine – with more interconnectivity features.

Wayne Grayson:

Volvo, Komatsu and Caterpillar have all unveiled autonomous haul trucks, with Cat planning a major expansion of its global fleet. But the real sign of momentum behind autonomous construction machines came with the unveiling of an autonomous compact track loader from Built Robotics. This robotic CTL uses LiDAR to navigate the jobsite along with GPS sensors and machine control technology for following site plans without an operator.

Look for 2018 to bring more big moves toward autonomous equipment. As Denise Johnson, Caterpillar Resource Industries group president, put it in September, “Autonomy is no longer an experiment.”

Little Beaver intros towable hydraulic earth drill

Categorías:
29/12/2017

Little Beaver’s Towable Hydraulic Earth Drill has a balanced frame that reduces operating weight by roughly 50 percent, compared to traditional hydraulic drills, according to the company. The drill frame balances the weight of the drill over the wheels and requires less than 20 pounds of force to pivot into digging position.

In addition, the frame eliminates torque for safe, one-person operation, pivoting into position without damaging turf or landscaping. The unit can be transported via a removable no-tools towing hitch, saving truck or trailer space.

It has an 11-horsepower Honda engine and a 2,700-psi hydraulic system that provides up to 300 foot-pounds of torque with 150-rpm auger speed. The unit’s 34-inch width enables it to pass through gates and other tight spaces perhaps inaccessible to skid steers. The two-position handle rotates 180 degrees to drill near buildings, walls and other structures. The forward and reverse auger rotation control is placed on the handle and a built-in pressure relief valve activates if the drill reaches a certain hydraulic pressure, safely stopping the auger.

The drill is compatible with the company’s 36- and 42-inch standard and carbide augers, which come in 1.5- to 18-inch diameters. A rock snap-on auger is also available, and comes in 6- to 16-inch diameters. Spring-loaded snap buttons secure the auger to the drill head, eliminating the need for tools. The drill’s infinitely variable 20-degree auger tilt makes it possible to drill vertically in uneven terrain.

Used for fence and deck building, along with sign installation, the drill is also available for rental companies and park and recreation departments.

Ram recalls 1.48 million trucks over shifter defect

2016 Ram 5500 Chassis Cab

FCA is voluntarily recalling an estimated 1.48 million trucks in the U.S. to help prevent occupants from inadvertently moving the vehicles’ gear-shifters out of the ‘park’ position.

The recall is limited to vehicles equipped with shifters mounted on their steering columns. Those with rotary-dial shifters or floor-mounted shifters are unaffected.

An FCA US review of field data led to the discovery that Brake Transmission Shift Interlock (BTSI) may not function properly if subject to specific high-temperature conditions for prolonged periods. The conditions are consistent with those that occur when there is protracted brake-pedal application while a vehicle is idling in park.

If BTSI becomes disabled, a vehicle’s shifter may be moved out of park without brake-pedal application, or the presence of a key in the ignition. In such circumstances, a vehicle may exhibit inadvertent movement – if its parking brake has not been set, as recommended in FCA US owners’ manuals.

The company is aware of seven potentially related injuries and a small number of potentially related accidents.

“FCA US will restore BTSI function in the vehicles subject to this recall,” advises Tom Mc Carthy, head of safety compliance and product analysis. “Nevertheless, as always, we urge customers to use their parking brakes, as recommended, and to ensure that child occupants are not left unattended.”

Affected are certain 2010-2017 Ram 2500 and 3500 pickups; 2011-2017 Ram 3500, 4500 and 5500 chassis cabs; 2016-2017 Ram 3500 chassis cabs with a Gross Vehicle Weight Rating (GVWR) of less than 10,000 lbs. Certain 2009-2017 Ram 1500 pickups are also included in the campaign. Certain 2009-2017 Ram 1500 pickups are also included in the campaign, but heavy-duty trucks represent the majority of the affected vehicles.

All model-year 2017 trucks built after Dec. 31, 2016, are excluded.

Additional populations of these vehicles are also being recalled in Canada (est. 249,520); Mexico (est. 42,747) and certain markets outside the NAFTA region (ext. 14,950).

Affected customers will be advised when they may schedule service. FCA US urges all customers to heed the instructions on recall notices.

Customers with concerns may call FCA US at (866)-220-6747.

Golden Gate Bridge earthquake retrofit moves into final stage

Categorías:
29/12/2017

A five-year, $660 million plan is in the works to protect the Golden Gate Bridge from large earthquakes.

The retrofit project would begin in 2019 and end in 2024, provided funding and necessary approvals are in place, according to the San Francisco Chronicle.

The newspaper reports that the Golden Gate Bridge Highway and Transportation District has only about one-third of the money needed for the project.

The project involves installing 38 custom “energy-dispersal devices” that are 17 feet long and cost about $1.5 million each, the Chronicle reports.

This is the final phase of a 20-year project to shore up the bridge. The project followed the 1989 Prieta earthquake, which did not damage the bridge but concerned the bridge district about its ability to withstand future large earthquakes.

The district has performed the following retrofit projects on the bridge, according to KTVU news station: retrofitted or replaced the Marin County and San Francisco sides and has ensured the bridge would not collapse in an earthquake even if it were damaged.

The latest project also includes adding a suicide barrier, a model of which is being tested.

Alligator Bridge to NC’s Outer Banks to close for renovations

Categorías:
29/12/2017

Efforts are underway to renovate the Alligator Bridge, which links to North Carolina’s Outer Banks.

The drawbridge will be closed to boat and road traffic from 12:01 a.m. January 10 to January 16, according to the N.C. Department of Transportation. Workers will take that time to replace and repair electrical and mechanical components beneath the swing span, the NCDOT says.

The NCDOT has undertaken a $16.7 million project to renovate the 58-year-old span. Flatiron Constructors of Morrisville, North Carolina, is the contractor.

NCDOT says detour signs will direct motorists to these detour routes:

  • Motorists traveling east from Columbia should use N.C. 94 South to U.S. 264 East to U.S. 64.
  • Motorists traveling west from Dare County to Columbia should use U.S. 264 West to N.C. 94 North to U.S. 64.
  • Motorists traveling to the Outer Banks from areas west of Williamston should use U.S. 17 North to U.S. 158 East.
  • Motorists traveling from the Outer Banks to points west of Williamston should use U.S. 158 West to U.S. 17 South to U.S. 64 West.

The project will require another week-long bridge closure in March, at a date to be determined the NCDOT says.

2,575 citations issued during N.D. ‘Click it or Ticket’ campaign

Categorías:
29/12/2017

In North Dakota, a traffic campaign that beefed up enforcement patrols has led to 2,575 citations between November 1 and December 15.

Of the total citations issued in the “Click It or Ticket” campaign, 924 were citations for failure to wear a seat belt and 30 were child restraint citations, reports the North Dakota Department of Transportation. Speeding tickets totaled 941. The traffic stops also resulted in 31 drug arrests, nine citations for distracted driving and two citations for driving under the influence.

To date, nearly 61 percent of 2017 motor vehicle fatalities involved victims who were not wearing a seat belt, which is the most significant factor associated with motor vehicle crash injuries and deaths in North Dakota, the department says.

High-visibility enforcement for traffic safety is one element of a collaborative effort to reduce traffic deaths in North Dakota. Funding comes from federal grant money distributed through the North Dakota Department of Transportation.

Information on traffic safety initiatives can be found at ndcodefortheroad.org. Memorials to North Dakota crash fatalities can be viewed at ndcodefortheroad.org/memorial.

The Top 10 Construction Equipment Videos of 2017

Categorías:
28/12/2017

With 2017 drawing to a close, it’s time to take a look back at all the great videos we’ve come across in the last year. Refreshingly, this year’s Top 10 is light on the fail videos and heavy with cool machines going about their work.

These are ranked in order based on the number of clicks you, our dear readers (and watchers), provided. So join us as we take a look back by scrolling through the videos below.

#10: Cat M105 DEUCE a combat dozer that moves 6x as fast as a D5

What do you get when you throw some armor on a D5 and make it capable of speeds up to 30 miles per hour? You get a DEUCE.

The M105 Deployable Universal Combat Earthmover (DEUCE) was first produced by Caterpillar in 1999 under contract with the U.S. Army, according to a page at Military-Today.com. A total of 227 DEUCEs were made and the high-speed combat dozer was a purpose-built machine created to replace the use of Cat’s D5 in military service.

Cat powered the DEUCE with a 7.2-liter Cat 3126 engine delivering 185 horsepower in earthmover mode and 265 hp in traveling mode. The machine can be airlifted by the C-130 Hercules and upon being airdropped can be re-assembled for work in less than 30 minutes.


#9: Crane tumbles despite loader’s help with unwieldy load

An all-terrain crane is lifting a large billboard in place for mounting. And with this clip, the stupid begins right at the top.

At the spot the video begins, the machine’s back wheels are already completely off the ground. But it’s ok! These geniuses have strategically placed a loader beneath the back wheels of the crane to provide support via an extended bucket.

But in a shocking twist, the bucket is unable to keep the crane’s back end steady and eventually it tumbles forward, sending the crane and that billboard right on top of a nearby structure.


#8: How Cat builds D5 dozers: from bare steel to finished product

We got a rare chance to peek inside Caterpillar’s state of the art Athens, Georgia, facility to see a D5K2 dozer come together from cold, bare steel to finished product. (The factory also makes mini-hydraulic excavators, and D3K2 and D4K2 dozers as well).

The process uses a combination of hand-tack and robot welding, CNC machining, robotic powder coat painting, a lot of logistics and the deft touch of 1,400 skilled workers. Check out our video below to see in depth details on how the magic comes together.


#7: Excavator takes direct hit from land mine

According to the description accompanying the below video from LiveLeak, this armored excavator is working at the border between Chile and Peru as a demining vehicle. A few seconds in, a mine detonates absolutely rocking the excavator. Thanks to the heavy armoring, the operator isn’t hurt but is clearly shaken from the impact.

This type of work is necessary in Chile which, according to a 2014 article from Motherboard detailing the problem, is a country “littered” with land mines. The mines were planted in the 1980s under the dictatorship of Gen. Augusto Pinochet who, according to the article, “was in the midst of border disputes with all three of its neighbors—Peru, Bolivia and Argentina.”


#6: Crane flips while lowering backhoe into pit

The operator in the video below is lucky to be unharmed after his machine flips completely over while lowering a backhoe into a pit. As the machine begins to leave the ground you can actually see him notice that his wheels are airborne before deciding to bail.

Even after he escapes, it appears that he hits the ground within the footprint of the outriggers, one of which comes very close to hitting him.


#5: Caterpillar Buggy is a C12-powered hot rod with Studebaker body, 966 loader grille

“I wanted something that was a little different,” says hot rod enthusiast and builder Snapper Schomaker in a video where he explains the genesis of what he calls the Caterpillar Buggy.

The resulting hot rod definitely delivers on Schomaker’s original goal of “different.” When you see this vehicle rumbling toward you or even sitting still in the lot of a car show, you take notice.

So what makes a Caterpillar Buggy? Schomaker told Truck Trend he took the front end, 10-speed manual transmission, 425-horsepower Caterpillar C12 engine and a portion of the frame from a 1996 International 9200 tractor and married those components to a 1928 Studebaker Commander. He then installed the grille of a vintage Cat 966 wheel loader paired with the headlights of an old Cat 631 scraper.


#4: The Dumphoe was half excavator, half site dumper in one weird little machine

Based on information listed on the Keltec Engineering site dedicated to the machine, the Dumphoe was Frankenstein-ed together using Caterpillar machine components and was powered by a 92-horsepower Cat 3054T engine. The machine could dig, haul and dump and had a load rating of 6,000 kg (13,227 lbs). The unladen weight of the machine was 8,500 kg (18,739 lbs.). It had a two-speed hydrostatic transmission, two-wheel, four-wheel and crab steering and could travel up to 20 miles per hour. Controls were joysticks and it featured load sensing hydraulics.

It’s unclear when the Dumphoe was built (the below video was posted by Keltec in 2010) or if it ever went to market in any capacity, though it’s no longer listed under the Keltec product listing on the company’s new website.


#3: Large crane collapses while hoisting section of viaduct

A crane working on the construction of a viaduct in North Italy collapsed in May, and miraculously without any injuries.

According to a report from crane site Vertikal, the crane was performing a lift on a large piece of the viaduct in Varese May 9 at the Arcisate Stabio railway yards when it suddenly overturned.

Below are two videos of the incident. The first shows just the collapse itself while the second shows the moments leading up the collapse as well.


#2: Case unveils half dozer, half CTL concept DL450 as “Compact Dozer Loader”

Teased prior to ConExpo as “Project Minotaur,” Case Construction Equipment’s DL450 is billed as a “Compact Dozer Loader” that combines a compact track loader (CTL) with a dozer

Case says it has more than 30 patents pending on the DL450, which was named after the company’s former 450 dozer. The core feature of the DL450 is a C-Frame dozer interface that pins directly into the machine chassis. Case says it provides the stability and smooth operating plane of a CTL, ensuring that all operating power and stresses are channeled through the machine’s chassis and not its loader arms.

The C-frame can then be unpinned from the chassis and disconnected like an attachment, allowing the machine to perform as a standard CTL. The unit uses skid steer and CTL attachments.

The concept machine has an anticipated drawbar pull of around 21,000 pounds. The main body was created from the base frame of a vertical-lift Case TV380 CTL. Case then married the base frame with the radial-lift loader arm design similar to that of the former 465 skid steer.


#1: Power Dozer’s tracked blade can build earth walls, clear minefields, backfill like nobody’s business

While you might not see a Viking Power Dozer on most jobsites, there probably aren’t many earthmoving jobs that wouldn’t benefit from having it around. This dozer configuration makes quick work of backfilling and soil relocation but also has several military uses like minefield breaching and clearing. The first Power Dozer prototype was built in 1979 and the company built its first military-specific Cat D8N Power Dozer in 1998. The company says the machine’s unique design is the result of nearly three decades of experience in the pipeline construction industry.

What makes a Power Dozer a Power Dozer is its mechanized blade, which has the appearance of someone rigging an old set of dozer tracks they had lying around to the front of a blade. But look closer and you’ll see that the steel track’s design is flatter, more like a conveyor belt.

The variable speed and reversible belt is driven by two high-torque hydraulic motors and powered by an auxiliary diesel engine mounted on the rear of the dozer. On its website, manufacturer Viking Power Dozer Ltd. (VPDL) says the blade, which can raise, lower and tilt, can load and unload material “at incredible rates,” noting that when equipped, the machine is able to move more dirt than it weighs.

In an attention-getting move that’s one of the more memorable moments in the ongoing battle for pickup supremacy, GM sources revealed to the Wall Street Journal that the automaker will be offering carbon fiber pickup beds for its premium trucks within two years.

The new bed option is sure to attract plenty of attention and hopefully generate a new round of bed-testing videos. GM’s last bed videos from 2016 went viral and demonstrated the superiority of its steel truck bed over an aluminum version offered by Ford.

There was no mention of a carbon fiber bed when Chevy unveiled the 2019 Silverado, pictured above. However, at the event, the 2014 Chevy Silverado Cheyenne Concept with a carbon fiber bed was made available for reporters to drive.

But carbon fiber?! You need to watch a carbon fiber stress test video below to truly appreciate just how much stronger carbon fiber is over steel. The video, produced by BBC Engineering Connections, shows a steel drive shaft failing during a torque test at 1015 ft. lbs. while a carbon fiber shaft easily outlasts it until 3487 ft. lbs.

Okay, so while carbon fiber’s impressive strength and light-weight are no secrets, the real mystery here is price for the upgrade in a GM pickup bed.

For example, a primed, steel replacement hood for a 2015 Ford F-150 XL currently sells for $158.56 at discountbodyparts.com. A carbon fiber hood made by Carbon Creations for the same truck sells for $1,344 at realtruck.com.

Of course these are just two quick comparisons and don’t represent all prices for either material, but still, we’re probably not talking a slight bump in price here for the latest, greatest bed.

However, those in the market for premium trucks usually don’t dwell as much on price points and, if you think about it, having a carbon fiber bed is a premium bragging right that many will be more than happy to buy.
