WJ-1 underground loaders are mainly used in underground mine tunnels to shovel and transport loose materials after blasting. It can also be used in tunneling for railways, highways and water conservancy projects, and is suitable for tunnel workings with a medium cross-section above 3.0 m × 3.0 m.

Advantages and features

●Underground loaders is equipped with a low-speed Cummins engine that complies with Chinese National Standard III with large torque, liquid-cooled and low fuel consumption, low pollution environment, reliable in operation and easy to maintain. The exhaust system is equipped with muffler, which significantly reduces air pollution.

●Hydraulic transmission with variable pump, hydraulic motor, drive axles with spring brake hydraulically released, cut-resistant pneumatic tires for mining, all-wheel drive, high efficiency, effective braking, high reliability and long service life of tires. 

●The main components of the hydraulic system from well-known Chinese and foreign manufacturers have a stable performance, safety and reliability.

●The scraper chassis has a central articulated structure, and the frame and the rear drive axle are connected by a swing frame to improve the adhesion performance of the entire machine. The optimized working device and full hydraulic steering ensure flexible work and high operating efficiency.

●The working hydraulic pressure and steering hydraulic pressure adopt a combined system, which has high working efficiency and good reliability.

●All main pins of the scraper have adopted heat treatment such as high-frequency quenching, which greatly improves the reliability of the pins.

●Hydraulic scraper hoses and wires are covered with flame-retardant sheathing tubes and wax tubes to prevent fires caused by various oil products splashing after the hydraulic hoses and diesel pipes rupture.
