Ram’s TRX RexRunner Concept Pickup Truck Boasts 702 Horsepower

Published

on

The world’s quickest, fastest and most powerful factory production truck has gotten even more interesting.

Mopar transformed the 2021 Ram 1500 TRX into the Ram 1500 TRX RexRunner which carries a truckload of Mopar accessories and custom parts, elevating this apex predator to even greater levels of high-speed capability and durability.

Powered by the supercharged 6.2-liter HEMI V8 engine, rated at an eye-popping 702 horsepower and 650 lb.-ft. torque, the TRX RexRunner concept rides on 37-inch Goodyear tires mounted to custom-designed 18-by-9-inch Black Rhino Chamber wheels for a race-inspired appearance at all four corners.

Debuting at SEMA, the TRX RexRunner concept wears Ash Gray paint and several Mopar Blue accents, including a center stripe that extends over the hood and roof, TRX bedside graphics, Ram grille and dual tow hooks up front. A RamBar accessory bar features a pair of concept 14-inch TYRI rectangular LED lights, generating 4,300 lumens of exceptionally bright light. Just below the RamBar, a fully integrated, bed-mounted spare-tire carrier from Mopar keeps a 37-inch spare tire/wheel at the ready.

For bed protection, the TRX RexRunner concept features a black, Mopar spray-in textured bedliner.  Custom metal skid plates feature laser-etched Mopar lettering and protect the front and rear underside areas of the truck. Use of the front skid plate helps to increase the approach angle by 2.3 degrees up to 32.5 degrees.

Mopar rock rails also help protect the side sills from any damage, while a custom, black, flip-top, fuel-filler door adds to the rugged exterior. Just below the rear bumper, look for a pair of 5-inch black Mopar exhaust tips. A Mopar bed step features an articulating arm that lowers for easy access to the truck bed and, with a slight push, retracts to a stored, out-of-the way position.

The race-inspired interior of the TRX RexRunner concept draws on a combination of features from production versions of the Ram 1500 TRX and the workhorse Ram 1500 Tradesman.  From the award-winning TRX production model are the center stack, instrument cluster, flat-bottom steering wheel with paddle shifters, center-console-mounted floor shifter and aggressive bolster sport seats.

In addition, Mopar stainless-steel pedal covers feature black rubber pads, providing additional traction to the accelerator and brake pedals. Additionally, molded one-piece door panels and a vinyl floor from the Tradesman model allows for quick and easy cleaning.

TxDOT issues default to Flatiron/Dragados for New Harbor Bridge

Published

By

The Texas Department of Transportation has issued a notice of default to the contractor on the future Harbor Bridge in Corpus Christi over safety concerns.

TxDOT says the contractor, the Flatiron/Dragados LLC joint venture, “has refused to acknowledge the safety issues that have been identified or taken any steps to correct them.”

The default notice gives Flatiron/Dragados 15 days to present a plan to correct the problems or face termination from the $803 million project to build the second-longest cable-stayed bridge in the U.S. The new bridge will replace the current Harbor Bridge that carries U.S. 181 over the ship channel at the Port of Corpus Christi.

The default notice follows TxDOT’s July 15 suspension of work on the cable-stayed section of the bridge for safety concerns, including the possibility of collapse under certain load conditions. The agency says it notified Flatiron/Dragados of the problems April 29 and that it “has consistently communicated its concerns…about non-conforming design flaws.”

“There were assurances by Flatiron/Dragados that these issues had been addressed,” said TxDOT Executive Director Marc Williams.

Equipment World is seeking comment from Flatiron/Dragados concerning the default notice.

The safety concerns over the design of the bridge, construction of which began in 2016, surfaced in 2020. The bridge’s engineer, FIGG Design Group, was fired by TxDOT that year following a report that blamed the firm for the 2018 fatal collapse of a pedestrian bridge under construction at Florida International University in Miami. FIGG was replaced by a joint venture of Arup and Carlos Fernandez Casado, called Arup-CFC, as the engineer of record. The new engineering team was hired by Flatiron/Dragados.

TxDOT says the safety issues include the foundations, load and weight capacity, structure and the stability of the main stay bridge. TxDOT hired SYSTRA International Bridge Technologies (IBT) in 2020 for a third-party review, and it confirmed the agency’s concerns, TxDOT says.

In a July 15 letter to Flatiron/Dragados, TxDOT outlined the following safety issues cited in IBT’s report:

  • inadequate capacity of the pylon drilled shafts,
  • deficiencies in footing caps that led IBT to report that the bridge would collapse under certain load conditions,
  • delta frame design defects, primarily related to the connections between the delta frames and the adjacent precast box units,
  • significant uplift at the intermediate piers
  • excessive torsion and other stresses related to crane placement during construction.

The letter states that Flatiron/Dragados and the engineering team of Arup-CFC “continue to deny any problems with the design despite ample evidence to the contrary.” The letter adds that “TxDOT does not believe it is responsible or safe to proceed with the erection of the NHB (New Harbor Bridge) superstructure (including, but not limited to the delta frame installation) because that work exacerbates four of the five major issues raised by IBT.”

The letter concludes: “Based upon the independent analysis performed by IBT and the resulting concerns about the ongoing erection of the NHB superstructure, TxDOT has concluded that there is or will be an emergency or danger to persons or property related to the design deficiencies.”

TxDOT says it does not yet have a timeline on when construction could resume on the cable-stayed portion of the bridge, but says it will ensure it is built to the highest quality standards.

The bridge is scheduled for completion in 2024, although that date is now in doubt. Currently, drivers are using the existing 2.25-mile steel bridge built in the 1950s. It will be demolished after the new bridge is completed.

The new bridge will have three lanes in each direction, consisting of 6.44 miles of bridge and connecting roadway, according to TxDOT. Its main span will extend 1,661 feet and become the second-longest cable-stayed bridge in the U.S. and Canada when completed. The Gordie Howe International Bridge between Detroit and Canada will have the longest cable-stayed span, of 2,799 feet, when completed, also slated for 2024.

When it’s time to buy a new compact track loader

Published

on

By

Compact track loaders have emerged as the darlings of the construction industry.

They’re versatile, productive, comparatively low cost, and easy to operate and transport. They provide excellent value even when subjected to the worst management practices.

So how do you get the most out of your CTL? How do you know when it’s time to trade up? And what features should you look for when buying a new compact track loader?

We have the answers here, along with a rundown of the latest compact track loaders on the market:

Buy new or stay put?

Unlike production machines such as wheel loaders, CTLs have widely varying utilization rates and widely varying duty cycles when serving in multiple applications. Because of this, it’s hard to know when to replace CTLs with new models.

“A lot depends on the customer,” says Buck Storlie, ASV product manager. “Some run the machine for a long time, up to 8,000 hours. Others trade in at the first major service, such as an undercarriage rebuild.”

Storlie points out that downtime from an older machine can be more costly than the acquisition of a new one. “Risk goes up with time; so much of the decision of when to buy new comes down to the customer’s risk tolerance.”

Deere SmartGrade 333G compact track loader with dozer blade climbing up dirt pileThe vertical-lift John Deere 333G has a Yanmar engine rated at 100 net horsepower and an operating weight of 12,100 pounds. Attachments for this and other large-frame Deere CTLs include mulching heads, grapples and snowblowers. The optional EH Boom Performance Package provides self-levelling up and down or up only, return-to-carry, return-to-dig and boom height kickout.John DeereFor risk-averse customers, a warranty provides peace of mind, which can also determine when to buy a new CTL.

“There is no single best answer as to when to buy new,” says Luke Gribble, solutions marketing manager, John Deere, “and with simple maintenance, CTLs can last a really long time. But a lot of customers want to stay in warranty coverage, whether standard or extended, and they set replacement cycles based on that.”

Kevin Coleman, Cat product specialist, says simply monitoring machine health can be a good way of determining when to replace a CTL. “A strong maintenance strategy ensures equipment health but also identifies emerging issues, as does fluid analysis.”

He says an intuitive operator notices and should report changes in the way the loader feels and performs. Owners should closely track ownership costs, especially maintenance costs and repair costs, “which are two separate items,” says Coleman, “even though they often get lumped together as ‘maintenance-and-repair costs’ in communication.”

ROC is 2,220 pounds at 35% of the 6,345-pound tipping load. Operating weight is 10,095 pounds. The available Advanced Display provides on-screen adjustments for implement response, Hystat response and creep control as well as customizable layouts and rearview camera monitor.CaterpillarAnother key indicator on when it might be time to trade-in: the tracks.

Ryan Anderson, product marketing manager, New Holland Construction North America, says tracks are the most vulnerable part of an undercarriage and can indicate wear on other parts of the system.

“Tracks are expensive in themselves at $2,500 or more per side, but accelerated track wear or premature track failure is a good indicator of excessive wear or imminent failure of other components, which also gets expensive in a hurry,” he says. “Track life can be a good indicator whether it’s time to replace that machine.”

The FPT engine is rated at 114 horsepower. Relief pressure is 4,100 psi, and flow is 41.6 gallons per minute. ROC is 6,200 pounds at 50% of the 12,400-pound tipping load.New Holland

When new makes sense

New machines project a better image of the company and help in attracting and retaining operators. Coleman advises determining whether a particular CTL is a core or support machine, and make replacement decisions accordingly.

Two other considerations: CTLs tend to hold their residual value well, so there’s no sweet spot in the depreciation curve to encourage replacement. Second, if the CTL is mainly a bucket-and-forks machine, it can likely continue to serve well in that capacity for a long time.

Also, if you want equipment that can go beyond buckets and forks, or you want to use bigger buckets and forks, it makes sense to move up to a new loader.

“For contractors looking to break into a new market or type of job, a new CTL can provide significant application enhancements through increased power, productivity, fuel economy and jobsite efficiency,” says Mike Fitzgerald, Bobcat marketing manager.

He says the R Series loaders from Bobcat were designed to be stronger and more durable. As an example, the lift arms on the R Series use cast steel components that are 20% stronger than fabricated steel. Lift arm profile is also smaller, improving visibility for the operator.

System relief pressure is 3,500 psi at the quick-connect couplers. Standard auxiliary flow is 23.3 gallons per minute; the high-flow option provides 30.3 gpm. Rated operating capacities are 2,900 pounds ISO and 4,143 pounds at 50% of tipping load. Joystick control is standard.BobcatAdam Devins, Wacker Neuson product manager, goes back to costs. The graph of costs should resemble a hockey stick, with a long, flat stretch of consistent costs and a sharp upslope where costs suddenly escalate with machine hours. “That inflection point will signal the time for replacement.”

Depreciation can be tracked similarly, he says. If conditions arise so that the depreciation ticks up sharply (or residual value falls steeply), “trade-in value might be the tipping point for the feasibility of purchasing a new CTL.”

Other signs it’s time to go new

Do you often rent or borrow a CTL because the one you own is not up to the tasks you’re performing?

“You may be able to perform those tasks with a newer, more capable machine,” says Jeff Jacobsmeyer, Case product manager. “It boils down to a basic discussion of whether you can perform the work you need to do with the tools you have. If not, you may be better served with a new machine.”

Case TV620B compact track loader in woods mulching brushThe vertical-lift Case TV620B has an FPT engine rated at 114 horsepower and an operating weight of 16,300 pounds with operator and fuel. Maximum travel speeds are 8.7 mph for rubber tracks and 5.9 mph for steel tracks in high range. Pressure is 4,351 psi, and flow is 24.2 gallons per minute standard or 41.6 gpm with the high-flow option. Track length on ground is 74 inches.Case CEEthan Clowes, JCB product manager for skid-steer, compact-track and backhoe loaders, lists features commonly available on newer models that may be lacking on older machines that could make big differences in productivity and profitability. Among these are telematics, smooth ride systems, creep speeds, power quick hitches, air suspension seating and controls tunable to conditions and operator preferences.

The ability to move more material per hour or with less fuel per unit of material provides other likely advantages of buying a new machine.

Given the versatility of new CTLs, Clowes says, “if you have an application that requires two machines, and that application can be accomplished with one new machine of greater production or versatility, then you could save money with that single new machine rather than two existing machines plus two operators.” He cites the JCB Teleskid 3TS-8T for the extreme versatility afforded by its telescoping boom.

Powerboom allows side-door entry and exit and contributes to 60% better operator visibility than other CTLs. While machines can be spec’d to meet customers’ unique needs, JCB offers its Yellow Series of machines in the most popular configurations for quicker acquisition, as well as Teleskid and Forestmaster configurations.JCB

Coleman notes that while incremental advances in performance, operator comfort and productivity in new machines all have value, the greatest value is found in the most significant advances. Cat’s Smart Dozer Blade, Smart Grader Blade and Smart Backhoe attachment are such advances, he says. Each integrates the attachment with the CTL.

Guidance for buying a new CTL

Now that you’ve made a decision to buy a new CTL, it’s time to decide on the type of machine.

The fundamental decision in buying a compact track loader, says Lee Padgett, Takeuchi-U.S. product manager, is radial or vertical lift.

The rule of thumb is that radial lift is best for applications done from where the lift arms are horizontal and below, such as grading and dirt work. Vertical lift is better for applications with the arms above the horizontal centerline of the machine, such as load-and-carry and truck loading.

Padgett says the second fundamental decision is standard or high-flow hydraulics.

“Customers who want versatility should choose a machine with high-flow hydraulics because that will increase the range of attachments the machine can use. If they have a broad service menu or know they want to expand the services they offer in the future, high flow is the smart choice.”

High flow also boosts residual value and marketability of the loader when it comes time to trade it in or sell it.

So why not just get the high-flow option and be done with it?

“If they specialize in one specific task or know they’ll be able to work efficiently with standard-flow attachments, they may not benefit from the additional investment required for high-flow hydraulics,” says Padgett.

The Kubota engine is rated at 111 horsepower. Hydraulic pressure is 3,481 psi with standard flow of 23.2 gallon per minute and optional high-flow of 40.4 gpm. The cab features a new design with low-effort overhead door for improved entry and exit.Takeuchi

Track tread pattern is another fundamental consideration, says Coleman.

Cat offers two patterns: bar and block. The bar tread pattern is the best for general, all-season use, including snow removal. It creates minimal surface disturbance and is therefore preferred for grading. The block style tread is a rugged pattern style and works well in rough terrain, in aggregate and for rental machines.

When it comes to operator comfort, suspension is also a key consideration.

Storlie says that although suspension provides significant improvements in operator comfort and load retention, not all OEMs offer it as standard. Non-suspension models are provided to hit price points, especially in the rental market.

“ASV has been doing suspension for over 30 years, and it’s standard on all our CTLs,” he says.

Available on larger ASV models is a dual-level system where the idler wheels have torsion suspension to isolate them from the undercarriage, and the undercarriage has torsion suspension to isolate it from the operator.

Many new models have entirely new feature sets; so it’s important to understand what those are and the value they offer. Telematics is one of those features buyers should focus on.

“The Case TV620B features the SiteConnect module,” says Jacobsmeyer, “which provides greater flow of telematics data and also serves as the gateway for remote connectivity.” With the SiteConnect module and SiteManager app, owners can grant dealers remote access to their machines for faster diagnosis and repair if problems develop.

Regardless of how the decision is made to replace a CTL, Devins says, customers should have a plan for acquiring a new machine. Lead times are currently long, and availability at the local dealer is likely to be limited.

CTL maintenance

Kubota SVL97-2 compact track loader hauling concrete fragments in bucket over dirt groundsStandard features on the Kubota SVL97-2 include self-levelling of the bucket during lift and two-speed travel for a 7.3 mph top speed. Horsepower is rated at 96.4; operating weight is 11,574 pounds (cab), and ROC is 3,200 pounds at 35% of tipping load. The vertical-lift design provides 128.5 inches of hinge pin height and 40.7 inches of reach.KubotaNow that you’ve bought your new compact track loader, here’s some guidance on how to maintain it.

When it comes to CTL maintenance, first and foremost is track adjustment. It is often overlooked and should be part of daily inspections.

A track that’s too loose accelerates track wear and may result in the track coming off. A too-tight track accelerates wear on other undercarriage components as well as the track itself.

Padgett says other daily checks include fluid levels. Fuel/water separators should be drained. Look for damaged lines and cylinders and hydraulic leaks. Clean hydraulic couplers before connecting attachments. Keep an eye on hydraulic oil temperatures, especially when running high-flow attachments such as mulchers. Keep debris out of the tracks.

Anderson says a clean cab is important for operator comfort by reducing odors and the annoyance of objects clattering around on the floor. It also sets a standard of professionalism for the operator.

On the area below the cab, or the “bathtub” of the machine, dirt and litter can collect, impeding cooling and even posing fire risk. The area is filled with hoses and connectors, which are potential fail points.

“This area is not normally seen by the operator nor is it part of a daily walkaround,” says Anderson, “yet conditions that can lead to unexpected downtime are often first seen here. It’s important to schedule regular inspections and cleaning of this area.”
