However, this isn’t an electricity/fuel hybrid like the automobile industry has segued into. Instead, Cat developed a new hydraulic hybrid technology that it says allows the new 336EH to get up to 25 percent greater fuel efficiency than the standard 336E and up to 50 percent greater fuel efficiency over the Cat 336D.

“We wanted to accomplish this hydraulically instead of electrically,” says Ken Gray, Caterpillar’s global product manager for large hydraulic excavators. About 98 percent of the components on the new excavator are currently standard, and the 336EH will be the largest hybrid excavator in the world, the company says.

“To us, the term hybrid means taking extra energy and storing it until it can be used,” Gray says. “It doesn’t matter what kind of energy is stored. One plus: it will be the quietest machine in its size class, with a 65.2 decibel sound level.”

“The difficult part of it is how to control the flow,” he adds. “That’s where the real intellectual property is.”

Machine design on the 336 started back in 2009, but the design on some of the hydraulic components goes back further. Cat says it made the decision to go all-hydraulic in 2011, choosing the all-hydraulic approach because of the high power density of hydraulics.

“It works a lot like a clock coil spring,” Gray says, taking advantage of the excavator’s swing cycle and the fact that there are two start-stops in a typical 15-second load and dump cycle. When the machine slows, the hydraulics store energy that will be reused when it swings again. “It’s the first hybrid machine that will actually lower a user’s owning and operating costs,” Gray says.

Cat is using three main new components to conserve, optimize, and reuse hydraulic power:

• Electronic Standardized Programmable Pump: By matching the engine and pump closely, Cat can use a larger displacement pump and significantly reduce fuel consumption;
• Adaptive Control System: The brains of the system, this directs the flow of the energy throughout the machine; and
• Hydraulic Hybrid Swing System: This takes otherwise wasted swing braking energy and recovers and reuses it.

“I can’t talk about the price, but customers will be able to pay for it within 12 months, or 2,000 hours,” Gray says. “To us, a seven-year payback on a hybrid doesn’t make sense.”

Before its launch at bauma, customers can begin placing orders through Cat dealers in February 2013. Shipments will begin in April.

Vacuworx Global Barrier Lifter

The Vacuworx Global Barrier Lifter, based on vacuum-based technology for heavy-duty lifting equipment, is designed for use with a large variety of host equipment in confined spaces with mobility restrictions. Off-loading and installation is extremely fast, which significantly reduces turnaround time and ground personnel – and both personnel and equipment have a dramatically reduced amount of time of exposure, according to the manufacturer.

The lifter can work effectively with all sizes of barriers and has a four to one safe working load capacity of 7,500 pounds. The lifter is completely self-contained with an integrated diesel engine and operates with a matched tolerance gearing system that permits optimum operation for both the engine and vacuum pump helping to create maximum continuous output and longer run life.

Doosan DL200

Doosan has upgraded its DL200 and DL220 wheel loaders to bring them in compliance with Tier 4 interim regulations. But the improvements don’t stop there as both loaders have benefited from increased horsepower and performance.

The 2.6-cubic-yard DL200 now boasts 160 horsepower over the 143 horsepower of the previous model. With a breakout force of 22,230 pounds, the new DL200 sees a bit of a dip from the previous model which had a breakout force of 23,149 pounds, according to the Equipment World 2012-2013 Spec Guide. However, the dumping height gets a boost from 9 feet, 2 inches to 9 feet, 6 inches in the new model. The DL200 is also available in a high-lift configuration, extending the dump height 15 inches above the standard DL250, to 10 feet 9 inches.

The 3.0-cubic-yard DL220 received a boost in horsepower, from 148 to 160, and breakout force, from from 22,928 to 23,650. The dump height is now 9 feet, 3 inches, down one inch from the previous model. 

Both wheel loaders are powered by a 6-cylinder, turbocharged diesel engine with a high-pressure common-rail (HPCR) design with direct fuel injection, electronic control and four valves per cylinder. Each loader’s new auto-idle feature provides additional noise reduction and fuel savings by reducing the working idle of the wheel loader from 950 rotations per minute to a standby idle setting of 750 rpm when the machine is inactive for a short period of time.

Doosan says the DL200 and DL220′s ability to set upper and lower limits for the lift arm and bucket stop positions from inside the cab translate to improved lifting performance while an optional fourth spool control valve provides operators the capability to use an attachment that requires an additional hydraulic function, such as snow blowers and snow blades. The new loaders also use an automatic-reversing cooling fan that keeps them going in dirty and dusty conditions.

Doosan DL220

In addition to several interior cab improvements, driving performance has been improved. These machines come standard with a limited slip differential, but an optional hydraulic locking front differential is available as well. This option provides increased driving power when one wheel spins or loses traction and improves machine performance when navigating tough terrain by allowing the operator to lock the differential manually or allow the machine to automatically engage the system. 

Doosan says the new 542-cubic-inch engine inside the DL200 and DL220 provides a more efficient combustion that in turn produces more torque and improved fuel economy, less noise, lower operating costs and cleaner exhaust. In addition, service intervals on the front lift arm pins have increased from 50 to 250 hours, and tilt cylinder hydraulic hoses have been rerouted for improved hose reliability, better hose movement and improved visibility to the attachment.

The SuperMaxx series includes the 9300X, 9500X and 9800X, available with 3.3-, 4.3- and 6.0-cubic-yard capacities, respectively. The spreaders feature a unique cab-forward design with up to 33 percent better payload distribution, resulting in improved safety and reduced stress on the carrying vehicle.

Exclusive to the SuperMaxx series, the spreaders include a patented wet/dry mixing chamber. Within the chamber, the auger feed system mixes brine with the spreading material before delivering it to the spinner. This feature maximizes the effectiveness of pre-wetting applications by ensuring a precise, even coating of brine.

The hoppers are made from corrosion-resistant polyethylene and include a multi-angle design to promote a continuous flow of material to the auger feed system. Furthermore, an inverted “V” baffle and attached vibrator reduce clumping and allow the units to spread all bulk materials, including 100-percent salt, 100-percent sand and any combination in between.

The spreaders are completely electric-powered with a 12-volt, ¾-horsepower auger motor and 1.6-horsepower spinner motor. To ensure durability and ease of maintenance, the motors and transmission are sealed within weather-resistant enclosures. The control panel is also protected in a weather-resistant enclosure with a clear inspection cover.

The SuperMaxx series is controlled by an innovative pendant-style controller with a digital readout and dials for independently adjusting the variable-speed spinner and auger. It comes with blast and pulse features, as well as auto-reverse and overload protection. If the truck is equipped with a pre-wetting system, the controller can toggle it on and off, automatically adjusting the pre-wetting system’s flow according to the spreader’s material feed rate.

Furthermore, a new low-profile spinner design with stainless-steel deflector helps the SuperMaxx series accurately spread material up to 40 feet wide. Additionally, the 12-inch stainless-steel spinner contains adjustable cups, allowing the operator to fine-tune the spread pattern. When not in use, the modular spinner assembly can be flipped into the upright position, providing full access to the vehicle’s hitch.

Other standard features include a fitted tarp, top screen, LED safety strobe lights, noncombustible wiring and vertically oriented ratchet straps. The spreaders are covered by an industry-leading two-year parts and labor warranty.

MB

MB’s two skid-steer loader mounted crushers, the MB-L 160 and MB-L 200, will allow the users of skid-steers to crush material with extreme efficiency.

They are specifically engineered to work within the specs of the skid-steers and loaders. MB America is already answering many calls from customers that want to improve the capabilities of their equipment fleet.

Kenco’s new generation (NG) Barrier Lift is the perfect attachment to handle concrete median barriers, sound walls, curbing and piling, or to align barriers that have already been placed.

Kenco furnishes attachments for excavators from mini to 200,000 pounds, wheel loaders from 1 to 40 yards, dozers, and skid steer machines.

Powered by John Deere (Tier 4) Turbo Diesel engines, the AZ-200C will pulverize up to 8-inch thick asphalt in a single pass. Easy to read and access controls and gauges along with active-hydraulic depth control and manual top hatch make it simple to use and maintain. Computer engineered cutter heads with replaceable bullet-head carbide tipped cutting teeth produce pulverized material with exceptional gradation that can be reused as road-base or backfill. Street patches, road repairs, base stabilization and opening utility trenches in asphalt are just a few of its many uses. Optional trailer also available.

Upgrades to Case N Series loader/backhoes include the application of cooled exhaust gas recirculation (CEGR) emissions-control technology to achieve Tier 4 Interim certification, as well as important improvements in performance, productivity and maintainability

Case Construction rolled out at World of Concrete 2012 in Las Vegas upgrades to its Case N Series loader/backhoes including the application of cooled exhaust gas recirculation (CEGR) emissions-control technology to achieve Tier 4 Interim certification, as well as improvements in performance, productivity and maintainability.

Although a costly but required venture, the move to Tier 4 presents an opportunity for success with Case Construction, Hasler points out. The company is owned by Italian parent company, Fiat, which already has the technology and has invested in on-road trucks, he says.

“Make no mistake,” said Jim Hasler, vice president of Case-New Holland, at a press conference attended by Aggregates Manager, Better Roads and Equipment World, during World of Concrete 2012. “We are only ones going down the path of SCR and EGR, [but] we believe SCR will prevail.”

The Case 580N, 580 Super N, 580 Super N Wide Track and 590 Super N loader/backhoes now feature 3.4-liter, turbocharged engines, ranging from 78 horsepower in the 580N to 108 horsepower in the 590SN. The Tier 4 Interim-certified engine — with CEGR technology — burns cleaner while delivering superior horsepower, faster response and up to 4-percent better fuel efficiency under load.

Automatic Ride Control is now standard on Case N Series four-wheel-drive models. Ride Control, a technology Case says it pioneered for loader/backhoes, now automatically engages at “roading” speeds to help reduce bucket spillage. New optional features include a block heater for cold-weather starting, and a remote jump start with master disconnect switch.
