Ⅰ.Application

WS3520 mining off-road dump trucks adopt the 6×4, wheel dump chassis. This truck have the advantages of strong power, large capacity, wide body, and excellent stability and adapt to the worse road condition such as in engineering construction and mine transportation as well as running off-way or on all types of roads.

Ⅱ.Function Features

1. Strong loading and wide application

The truck has large cubage and loading capacity, which can widely meet the demands of off-road construction and mine transportation.

2. Good traffic ability

Chassis of the trucks has higher ground clearance, larger approach angle and departure angle to ensure the well traffic ability.

3.Good stability

Ultra-wide driving axle and suspension, large output torque of hydraulic booster steering system. And large-size tires improve the functions of mobility, driving stability, convenient steering operation significantly.

4. Strong power

The truck model WS3520 is equipped with large power Cummins engine and high torque transmission model RT0-11509F.

5. Well braking performance

Truck is equipped with Dual-loop air braking system. Braking force acts on all wheels. Compressed air brake is performed by 2 independent air-ways connecting energy storage spring brake chamber and diaphragm brake chamber through air brake valve, air cylinder, relay valve and quick release valve. Braking system has the function of emergency braking performed by energy storage spring brake chamber when opens parking braking valve.

6. Flexible and convenient operation

The truck is equipped with hydraulic steering and braking system that makes convenient and flexible operation and reduce driver's fatigue.
