The electric LHD is a special loading and hauling machine designed for underground mines, taking electric energy as its power source instead of an internal combustion engine. Its operation depends on the coordinated work of the motor, hydraulic system, walking drive system and control system to finish scooping, hauling and dumping of ore and rock.

The main motor receives power from the underground power supply cable. It converts electric energy into mechanical rotary power and drives the hydraulic pump and travel drive assembly. The hydraulic pump transforms mechanical energy into hydraulic pressure energy. This hydraulic power drives the boom cylinder, bucket cylinder and steering cylinder, which control the lifting, curling and tilting movements of the bucket. The travel drive delivers power to the wheels and realizes forward movement, backward movement and flexible steering of the whole vehicle.

In the loading stage, the hydraulic system lowers the bucket. Driven by the traction of the wheels, the bucket penetrates the material pile. Then the bucket cylinder acts to curl the bucket and capture materials. The boom cylinder lifts the bucket to a proper height to avoid friction with the ground during transportation.

When hauling, the electric drive system provides stable traction for travelling in narrow tunnels. The hydraulic steering system adjusts the travelling direction freely. After reaching the unloading position, the bucket cylinder reverses its action to tip the bucket, and materials slide out under gravity to complete the dumping process.

The whole machine is regulated by an integrated electric control unit, which adjusts motor speed and hydraulic flow smoothly. It generates no exhaust gas during operation and brings lower heat release and noise. Without an exhaust purification system, it reduces the burden of underground ventilation. Reliable power regulation and sensitive hydraulic response allow the electric LHD to run continuously in confined underground spaces. It is a low-pollution and high-efficiency material transport equipment for modern underground mining.
