Crawler tractors Dong Fang Hong -1002J
1, the main purpose
Dongfanghong-1002-moving tractor was 1002 tractor gearbox ratios were adjusted on the basis of, reverse speed is more suitable for dozing, mainly for irrigation, pond repair, building towns small and medium Earth moving operations.
2, the main performance characteristics
1) use United Kingdom Ricardo developed in cooperation with the international advanced level of direct-injection engines, high power, low fuel consumption and good starting performance and long service life.
2) clutch dry, dual-disc, disc spring pressed joint type, long life, pedal control force is small, small external brakes when necessary.
3) in dongfanghong-1002 tractor reasonable on the basis of improved transmission gear ratios, optimizing the allocation of stalls, increased reverse speed, and improve operational efficiency.
4) ends transmission for simply supported beam, making more reasonable gear applied force; fixed rear axle housing baffle greatly improves the stiffness of the tank and the rear axle shaft and seal performance.
5) v pendulum block type hydraulic adjustment-oriented tensioning device, can effectively protect the front beam axle, chassis and other key components.
6) sealed, heavy car using floating seal and reliable sealing.
7) brake for bi-directional floating brake, which improves braking capability, adapted again, downhill braking requirements.
8) Steering with hydraulic booster, light steering effort.
9) full-enclosure fitted with an overhead heater, optional air conditioning unit.
