Brand 7 ton Motor Grader with Engine(GR1653)
Motor Grader GR1653
Engine model: 4BT3.9
Rated power/speed: 75kw/2400rpm
Operating weight(Standard): 7000kg
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 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.
External DesignThe engine housing adopots the glass steel which is of low- noise, rusty-proof, corrosion-prevention, anti-shock and being tiltable, so with nice looking and easy maintenance and repair for the engine.
BladeThe blade is of very hard material, and it is controlled by two cylinders for changing angle, so with perfect evenness and balance. And cutting-in angle could be easily controlled according to different soil conditions.
