Underground Mining load haul dump manufacturers Diesel scooptram 4.5m3 10Ton WJ-4

Compact and lightweight Load Haul Dump (LHD) for narrow vein mining. (Remote Control Available)

The loader comes with a ROPS and FOPS certified canopy, protecting the operator in case of rolling over or falling objects. The canopy door includes a door lock and latch mechanism with an interlock switch which automatically applies brakes and inactivates boom, bucket and steering when the door is opened. For better visibility from the operator’s position, adjustable high-power LED lights are a standard configuration. All-around operator visibility is further improved with a standard monitoring camera system including front and rear cameras. To improve overall safety underground, a Proximity Detection System (PDS) interface option is also available.

The DALI WJ-4 loader builds on the proven parts. It offers best in class performance in productivity by means of high ramp speeds and fast bucket filling, and to make truck loading easy, it features superior lift height compared to any other loader of the same size class. To achieve short cycle times and superior productivity, our renewed and compact WJ-4 underground loader provides the highest ramp speeds in its size class. The advanced powertrain technology includes a proven transmission with automatic gear shifting and torque converter ensuring fast ramp speeds to quickly clear tunnel headings. Durable axles use limited slip differentials to maintain traction and spring applied hydraulic release brakes for safer braking. Top speed can also be limited to improve safety in narrow tunnels and rough roads.

Structure

♦The frames are articulated with 38° 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.

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.

♦Hydraulic joystick control for working to reduce the labor intensity of the driver.

♦Low vibration level in cab

Early Warning & Maintenance

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

Enegy-saving & Enviroment Friendly

♦Germany Deutz engine with air-cooling and turbocharging, powerful and low-consumption.

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