Description

Technical Field

The frame is divided into front and rear sections and assembled together through an articulated body. This special structural shape can achieve a steering angle of ±42° for the frame. The rear frame can be twisted unlimitedly relative to the plane of the front frame. The left and right steering is achieved by controlling the movement of the steering cylinder. The articulated dump truck has the functions of driving, steering, braking, lifting, etc. The front vehicle of the articulated truck is mainly composed of the engine, gearbox and cooling system, which is convenient for heat dissipation and daily maintenance. The walkway extends from the outside of the hood to the maximum edge allowed by the vehicle body, and is used as a passage for getting on and off the cab and for maintenance. The hood should be as small as possible to wrap around the key components such as the engine, cooler, and pipelines to play a protective role. The front vehicle pipeline is mainly distributed in the front side of the cab, and the pipeline runs in the left and right direction, while the hydraulic pipeline is concentrated and has a large diameter.
