Carrying a Heavy Load
Hydrema U.S., Inc. says the cab of its 922C articulated dump truck sits high on the body and has an inclined narrow hood, which provides the operator with all-around visibility. Additional features include broad mirrors for added visibility when in reverse, a climate-control system for operator comfort, and user-friendly steering and joystick controls. The truck has a 15.7-cubic-yard capacity and automatically changes pressure between cylinders while dumping on uneven ground to prevent tip over.
Suspension system offers auto-leveling, stability
Volvo Construction Equipment says its E-Series articulated hauler is the world’s first hauler to offer a suspension system with automatic leveling and stability control on all wheels, providing extraordinary off-road performance, empty or full, and allowing higher speeds for increased production. The series includes seven models ranging in capacity from the 26.5-ton A25E to the 43-ton A40E. All are equipped with Volvo Advanced Combustion Technology Tier III engines to offer high torque at low revolutions to maintain fuel efficiency and reduce noise levels, according to the company.
Low center of gravity
Doosan Moxy, a division of Doosan Infracore America, says it has implemented specific design changes to its next generation articulated dump trucks to meet the demands of today. Changes include a sloping rear frame to ensure low center of gravity, stability, and weight distribution to the front axle. According to the company, the truck’s permanent six-wheel drive provides equal power distribution, and the free-swinging rear tandem bogie and special articulation system offer excellent driving performance in difficult terrain. Models range from the 20-cubic-yard MT26 to the 38-cubic-yard MT51.
