GR180 Motor Grader Features
Brake SystemThe travelling brake system adopts the hydraulic components of Rexroth (Germany). The hydraulic hub-type brake applies its performance on four middle & rear wheels. The parking brake system is of hub-type hand brake, which ensures the safety during travelling by applying its function on the output shaft of gearbox.
Steering system: Adopting sensor with load. The superior energy-saving fully hydraulic steering system makes it possilbe, with the articulated frame, to achive easy and flexible steering.
ChassisBeing of welded structure, just like a box, so it is strong enough to ensure no deformation.
Cabinwith wide-field vision, low noise, ultraviolet-protection glass, and with Curtis (of USA) or VDO (of Germany) instrument panel, height-adjustable seat, radio, ashtray, cup-seat etc. The cab is designed to be nice looking and very comfortable.
Slewing Mechanism: Be fitted with hard material lining, which ensures easy and flexible move of the blade, and high-accuracy flatness and low-cost maintenance as well.
Operation System: Forward/backward adjustable opertion pannel, with HUSCO multi-way valve, electrically- controlled ZF gearbox, so it is quite easy to make any operation.
Transmission: Adopting with auto-lock/unlock NO-SPIN anti-slide differential, heavy-duty balance box, heavy-duty roller chain transmisson, all of which make sure the transmission system being stable.
