Diesel LHD WJ-4


The WJ-4.0 is full of features to help mines maximize tonnes and minimize extraction costs. Engineered to optimize machine width, length and turning radius, enabling operation in narrower tunnels for less dilution and lower operational costs.


1. Operation Comfort & Safty:

• 4 wheels driving & braking.

• Combination design of parking brake & working brake ensures good braking performance. Braking model is SAHR(spring applied, hydraulic release).

• Front axle is equipped NO-SPIN differential. While rear is ANTI-SLIP.

• Low vibration level in cab

2. Early Warning & Maintenance:

• Automatic alarm system for oil temperature, oil pressure and electrical system.

3. Enegy-saving & Enviroment Friendly:

• Germany Deutz engine with water-cooling and turbocharging, powerful and low-consumption.

• Canada ECS catalytic purifier with silencer, which greatly reduces air and noise pollution in working tunnel.


The frames are articulated with 40° steering angle.

Ergonomics Canopy with side seat to provide good bi-directional view of operation.

An enhanced boom and load frame geometry optimizes digging performance.
