CATERPILLAR

Specially developed operator’s platform

Caterpillar has unveiled its very first hybrid excavator, the Cat 336EH. It is the first in an upcoming line of hybrid excavators and will be officially launched in April 2013 at the Bauma International Trade Fair in Munich, Germany. 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. Cat is using three main new components to conserve, optimize, and reuse hydraulic power (1)Electronic Standardized Programmable Pump: By matching the engine and pump closely, Cat can use a larger displacement pump and significantly reduce fuel consumption (2) Adaptive Control System: The brains of the system, this directs the flow of the energy throughout the machine; and (3) Hydraulic Hybrid Swing System: This takes otherwise wasted swing braking energy and recovers and reuses it. http://tinyurl.com/Cat-336H-hybrid

3M

Gloves improve traction and hold

3M’s WorkGloves are made with the manufacturer’s proprietary Gripping Material, which is said to provide up to a 270-percent improvement in friction when used as a two-part system, which mates the gloves with tools or piece of equipment wrapped with 3M Gripping Material tape, improving friction over traditional leather gloves and wraps. 3M says the gloves are especially good for wet or oily conditions and helps to enhance traction and hold on tools and pieces of equipment. The gloves are also resistant to abrasion and punctures. www.3M.com/gripping

HITACHI

Largest rigid dump with advanced AC drive

Hitachi Construction Machinery’s EH5000AC-3 rigid dump truck – the manufacturer’s largest – has 2,850 horsepower and meets U.S. EPA Tier 2 emission requirements. Powered by a Cummins QSKTTA60-CE diesel engine, Target Gross Machine Operating Weight (TGMOW) is 1,102,311 pounds and net machine weight is 449,743 pounds. The truck features the Advanced Hitachi AC Drive System, 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. http://hitachiconstruction.com/eh5000ac-3.html

BADGER

Compact crane for limited space

Badger Equipment’s 15 ton cab-down CD4415 rough-terrain crane is a compact model,just about 11 feet tall, making it ideal for jobs with limited space. The low-profile, high-capacity unit has a 15-ton rated capacity and a 10-foot working radius. Maximum boom length is 62.5 feet and maximum tip height is 85.5 feet. The boom is hydraulic-actuated in three sections with a minimum boom elevation of zero degrees and maximum of 70 degrees. The main hoist has grooved drum storage capacity. The hoist single-speed is standard. Hoist speed without load in fifth layer (low range/high range) is 242 fpm Hoist speed without load in the first layer (low range/high range) is 169 fpm.

DOOSAN

Cool mobile generators

Doosan Portable Power’s Tundra Package is designed specifically for its mobile generators to ensure they will run in temperatures as low as minus 40ºC/minus 40ºF. An engine coolant heater keeps the engine and cooling system warm, resulting in quicker starting time and less battery grind. An oil pan heater keeps the engine oil less viscous. High-capacity cranking batteries are equipped with a heating element to prevent the electrolyte from freezing, and to ensure that the battery does not lose charge in subzero conditions. A heated breather hose designed to prevent crankcase vapors from freezing in cold temperatures and blocking the breather, is powered directly from the generator and requires no external power.www.doosanportablepower.com

VOLVO

More material density, fewer passes

Volvo Construction Equipment’s SD75 soil compactor is a highly maneuverable, mid-sized machine. The soil compactor provides greater material density in fewer passes. High centrifugal forces, high frequency and drum weight all combine to produce the energy necessary for excellent compaction and high machine productivity, according to the company. Dynamic drum forces can be adapted to suit a wide range of terrain or depth of material. High or low amplitudes are selectable from the operator control panel. Additionally, two drum frequencies can be chosen with a console switch to compensate for changing soil types and conditions and an optional five-frequency feature further boosts the machine’s versatility and performance. A center joint provides +/-38 degrees of articulation and +/-17 degrees of drum oscillation for stable, flexible machine performance and greater operator comfort over rough terrain. Because the 66-inch-wide drum remains in constant contact with the ground surface, compaction is both smooth and uniform. www.volvoCE.com
