4 ton Mining LHD Underground Loader WJ-2

DALI WJ-2 LHD is a compact and lightweight narrow-vein loader designed for underground mining. It features a tramming capacity of 4 metric tons and a best-in-class payload-to-own-weight ratio. The WJ-2 loader offers three engine alternatives; a Tier 3 / Stage III A and two Tier 2 / Stage II, all from Deutz. The unit uses CMG or DANA axles, equipped with spring applied, hydraulically released brakes. The bucket alternatives include traditional bare lip buckets and an ejector bucket.

Advantages

●Proven design for narrow-vein mining
●Low operating weight reduces fuel consumption and extends tire life
●Small envelope size and turning radius enable easy navigation in narrow veins
●Ground-level daily maintenance enables safer servicing
The operator's compartment is ROPS and FOPS certified to improve safety underground, and efficient LED lights improve visibility. Safety can be further improve by equipping the loader with a fire suppression system, radio remote control and recovery kit.
Service brakes are hydraulically operated multidisc wet brakes on all wheels. Two independent circuits: one for the front and one for the rear axle. Parking brake is spring applied, hydraulically released dry disk brake affecting on the front axles drive line In case of a sudden pressure drop in brake hydraulics the parking brake functions as an emergency brake. Brake system performance complies with requirements of EN ISO 3450, AS2958.1 and SABS 1589
