WJ-1 is a compact and lightweight Load Haul Dump (LHD) for narrow vein mining, easy to operate and maintain, and it features an operator compartment that is located in the rear frame of the machine to ensure increased operator safety. The WJ-1 is full of features to help mines maximize ton and minimize extraction costs. It has been engineered to optimize machine width, length and turning radius, enabling operation in narrower tunnels for less dilution and lower operational costs.
Main Features
<< Structure
◆The frames are articulated with 38° steering angle.
◆Ergonomics Canopy with side seat to provide broad operation vision.
<< Operation Comfort & Safety
◆4 wheels driving & braking.
◆Combination design of parking brake & working brake ensures good braking performance. Braking model is SAHR(spring applied, hydraulic release).
◆Axles are equipped differentials. The front is NO-SPIN while the rear is standard.
