The book also has 394 materials specifications and test methods commonly used in the construction of highway facilities. The specifications have been developed and maintained by transportation departments through participation in AASHTO’s Subcommittee on Materials. The book edition is organized in two volumes, Materials and Testing, and each volume has consists of two books. Also included is the single-volume AASHTO Provisional Standards, 2012 edition, which contains eight revised and 14 new provisional standards.

Komatsu PC4000 hydraulic shovel

Komatsu’s PC4000 hydraulic shovel, with an operating weight between 855,500 to 879,800 pounds and a bucket capacity of 29 cubic yards, is designed to move more material in less time for reduced costs per ton and increased profits.

A powerful Komatsu SDA16V160E-2 diesel engine and four circuit advanced “

“Hydropilot” hydraulics are two of the major improvements to this model. The Komatsu SDA16V160E-2 diesel engine has a rated power of 1875 HP (1400 kW).

The shovel’s low engine emission levels meet U.S. Environmental Protection Agency regulations Tier II and oil management system is fitted as standard on all machines. Electric drive 4,16 kV to 7,2 kV, 50 or 60 Hz, is also available.

Hitachi EH5000AC3 rigid dump truck

Hitachi Construction Machinery‘s EH5000AC-3 rigid dump truck is powered by a Cummins QSKTTA60-CE diesel engine and meets U.S. Environmental Protection Agency Tier 2 emission requirements.

Target Gross Machine Operating Weight (TGMOW) is 1,102,311 pounds and net machine weight is 449,743 pounds.

The rigid dump truck, Hitachi’s largest, features the Advanced Hitachi AC Drive System for mining operations; the third-generation Hitachi Drive Control System with slip control for traction and slide control for grip; a pitching prevention for a smooth ride; a Slip Angle Control for stable cornering; an advanced braking system; and a Hitachi system monitor with onboard systems and controls information.

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.

Mack

“Certification of Mack’s entire vehicle portfolio reflects our continued commitment to fuel efficiency, environmental stewardship, and the country’s long-term energy security,” said John Walsh, Mack vice president of marketing, in a press statement.

Equipped with the new Cummins Westport ISX12 G heavy-duty natural gas engine, the Allison 4000HS transmission, and 115 diesel gallon equivalent compressed natural gas (CNG) fuel tanks, the Cascadia 113 natural gas tractor is ideal for regional haul and less-than-truckload applications.

The 12-liter ISX12 G natural gas engine is based on the Cummins ISX12 diesel heavy duty engine platform and will operate on either CNG or liquefied natural gas (LNG). It features ratings of 400 hp and 1,450 lb-ft torque, optional engine brake, and manual and automatic transmission capability.

Full production on the Cascadia 113 natural gas begins in Q3 2013.

Iowa Mold Tooling‘s revamped lineup of H20K167 and TH36K164 TireHand tire manipulators are available in loader or forklift truck-mounted options and provide capacities ranging from 5,500 to 36,000 pounds. The two new models – the TH20K167 and TH36K164 – offer 20,000 and 36,000 pounds of capacity, respectively.

Design enhancements include an optimized pad design that features a new grip pattern and tapering, enabling a firm grip on the tire without damage; increased arm length that allows the TireHand to reach the back flange on the wheels; a minimized arm profile that reduces interference with chassis components; dual pinion pad rotation that reduces pinion stress while increasing life; and 100-degree cylinder body rotation that moves the center of gravity closer to the machine, allowing a smaller loader to be used.

Integrated fallback protection arms are hydraulically controlled for easy operation and improved operator safety. The feature can be activated from the control panel or a remote control. Options include quick-coupler attachments, fully proportional controls and a mounted camera.

BOMAG BW100ADM-5 tandem vibratory roller

BOMAG’s BW100ADM-5 tandem vibratory roller features a specially developed operator’s platform that has a smaller diameter steering wheel, multifunctional travel lever, adjustable seat and circular instrumentation.

Powered by a 20.2-horsepower water-cooled Kubota diesel engine, the roller delivers 3,822 pounds of centrifugal force at a 3,780-vpm frequency.

The engine’s Ecomode system idles the engine while the roller is inactive. The roller, which has a 39.4-inch working width, has its travel motors contained within the drums instead of hanging from the drums, ensuring a compact design and boosting maneuverability.

Additional features include a 26.4 gallon water tank; pressurized spray system with triple-filtered nozzles; BOMAG Intelligent Vibration Control; spring-applied hydraulically released parking brake; ROPS with retractable seat belt; backup alarm; emergency stop button; front and rear lights for night operation; and lockable engine hood and instrument panel
