The WJD-0.75 electric scooptram adopts a three-phase asynchronous motor, rubber tires, simultaneous drive of the front and rear axles. And the hinge was changed to a slewing support, which changed the arrangement of the swing frame and three-point suspension hinge of the old model, overcomes the shortcomings of swing stand has high failure rate, maintenance trouble, serious safety hazards, greatly reduced investment in manpower and material resources, makes driving more flexibly and efficiently, operation is also simple and convenient. The walking system adopts full hydraulic control operation, makes the scooptram more responsive. In terms of safety performance, it integrates working brake, parking brake, and emergency brake. Spring brake, hydraulic release. During the walking process, cable synchronous winding and retracting, making the work more flexible. It is suitable for mining underground and tunnel excavation and slag removal, as well as auxiliary operations such as leveling work sites and roads, material transportation, etc.
