Product parameters of 4 Ton Crawler Dumper Truck
Half tracked vehicles are basically based on wheeled vehicles, with the rear wheels changed to tracked vehicles. After modification, the engine and gearbox of wheeled vehicles can continue to be used, and as many universal components as possible can reduce costs and facilitate mass production. During wartime, semi tracked vehicles are mainly used as auxiliary vehicles for tracked vehicles, with stronger off-road capabilities than wheeled vehicles. Although the original intention of the design was to take advantage of the strengths of both systems, it inevitably inherited the shortcomings of the two systems. The road speed is not as fast as wheeled vehicles, the off-road ability is not as good as tanks, the structure is complex, and maintenance is difficult. Even maintenance requires preparing two sets of tools.
Small tracked transport vehicles have good off-road capabilities and large climbing angles; This advantage adds a timely four-wheel drive system and hydraulic chassis, adding oil and explosive force, and the high and low speed systems are brought by high and low speeds; Although matching special engineering tracks increases the lifespan of the tracks, especially in off-road environments. In the production cost, there are a large number of Dongfeng original accessories. Engine options: Yuchai, Weichai Cloud, etc. The vehicle adopts a differential steering mechanism, which is controllable, flexible, more powerful, has a large track, and has a vibration damping effect. Due to the low ground ratio, it is light, especially in low wetlands, which can greatly improve operating speed and road transfer adaptability. The rubber track chassis is long, with low maintenance and transfer costs.
