Supply Lines: Workhorses of the quarry
Volvo Construction Equipment says its F-Series wheel loaders are the toughest, most fuel-efficient loaders on the market. Features include OptiShift with Reverse By Braking, which automatically assists deceleration; a T-linkage lift-arm system for greater breakout force; and the company’s CareTrack telematics system to manage productivity and maintenance.
With 48,060 pounds of breakout force and a fuel-efficient 280-horsepower Cummins Tier III diesel engine, Liugong says its 877III wheel loader is designed to compete with other models. Other features include a Z-bar linkage, 5.5-cubic yard bucket, ZF automatic powershift transmission, and automatic load-leveling system.
Extra-large payloads demand the use of extra-large wheel loaders.
The Liebherr L586 hydrostatic wheel loader has a 7.8-cubic yard capacity with an articulated tipping load of 45,050 pounds. Its fuel-efficient diesel engine produces 340 horsepower at 1,800 revolutions per minute. Cab displays and controls are arranged to form a precise, comfortable work environment.
Dressta North America offers several sizes of wheel loader; its largest offering being the 560E with a bucket capacity of 8.5 cubic yards and 427 net horsepower. Features include joystick controls for the boom and bucket, three-speed countershaft transmission, and wet internal brakes.
New wheel loader models offer more power.
Hyundai Construction Equipment Americas, Inc.’s new HL770-9 wheel loader features a load-sensing hydraulic system, a fully automatic power-shift transmission, multi-stage clutch cut off, integrated payload system, GPS-capable satellite system, 5.5-cubic yard bucket, and integrated rear-view backup camera. Large, removable housing doors provide easy access for service and maintenance.
