WJD-1 Underground Electric Shovel

The WJD-1 underground electric loader is a rubber-tired, articulated, front-mounted bucket loader powered by a three-phase AC motor, designed for both loading and unloading. It employs hydrostatic-mechanical transmission, four-wheel drive, a centrally articulated front and rear frame, fully hydraulic steering, and hydraulically controlled synchronous cable retraction and deployment. It allows for independent loading, transporting, and unloading operations by a single operator. Suitable for ore extraction and roadway excavation and slag removal in various mining methods such as staged caving, open-cut mining, room-and-pillar mining, ore retention, and layered backfilling, it requires a minimum operating clearance of 2.4 x 2.4 meters and a transport distance of no more than 80 meters. The travel system utilizes full hydraulic control, making the loader's movement more agile, effectively reducing the failure rate, and improving work efficiency. The cable reel system also uses hydraulic control, ensuring stable cable retraction and preventing cable damage. The parking brake uses a transmission gearbox with brake friction pads, spring braking, and hydraulic pressure release, ensuring safe and reliable parking. The bucket features a V-shaped structure, reducing scooping resistance.
