Body structure 

The trolley is mainly composed of cargo box, head, chassis, drive axle and suspension system. The front part integrates the cab, while the cargo box is used for loading materials. The chassis design is robust and adaptable to complex underground environments with good passability and climbing ability.

Rear bucket lift unloading material

When the vehicle is driven to the designated position and the material needs to be unloaded,

Through the action of a hydraulic or mechanical system, the back or side of the cargo box or carriage will gradually rise, so that the loaded material will automatically slide down under the action of gravity.

Instrument desk 

Fully enclosed cab, adjustable spring shock absorber seat, all operations (four-wheel drive shift, self-unloading shift, steering lock switch, parking handle) handle right, instrument table functions: engine water temperature, oil pressure, torque converter oil temperature, torque converter oil pressure, brake working pressure, protection 7 inch display, driving 7 inch display, gas horn button.

Fuel tank

The fuel tank is an important part of the trackless rubber wheel vehicle, which is responsible for storing fuel such as diesel for engine use. The fuel tank is usually located on the bottom or side of the vehicle body and is designed to have a reasonable capacity to meet the needs of long transportation. At the same time, the fuel tank also has leak-proof, explosion-proof and other safety properties to ensure the safety of use in the underground environment.

Axle

Front and rear steering wet brake engineering bridge, front bridge helical spring + damping shock absorption, heavy multi-link suspension, rear bridge main and auxiliary plate springs strengthen shock absorption.

Infrared distance sensor 

The front and back of the body are equipped with infrared ranging sensors, which can measure the distance between the vehicle and the surrounding obstacles in real time, and remind the driver to avoid the way through sound and light alarm. This function is particularly useful in complex environments such as mines, helping to improve the safety and reliability of vehicle driving.

Tyre

Tires 36×12.5-20 solid filled tires

Tire steering: The Underground Material Vehicle usually adopts hydraulic steering system, which realizes wheel steering through hydraulic pump and hydraulic cylinder and other components.During the steering process, it can maintain good contact between the wheel and the ground to ensure the stability and safety of the vehicle.
