The DALI WJ-1 is a compact 2-ton diesel underground LHD loader for narrow-vein mining and restricted headings. Its reference configuration combines a 1.0 m³ bucket, 1,300 mm machine width, articulated steering, four-wheel drive and hydrostatic transmission for loading and short-distance haulage underground. Remote control is available as an option.

The WJ-1 is a compact diesel load haul dump machine designed to load broken ore or waste, tram it over short underground routes and discharge it into an ore pass, stockpile or truck. Its 2,000 kg payload and narrow 1,300 mm body make it relevant to small headings and narrow-vein operations where access space is a primary selection constraint.
The machine uses a center-articulated frame, four-wheel drive and hydrostatic transmission. A rear-frame, side-seated operator position is intended to support visibility in both travel directions, while hydraulic joystick controls operate steering, boom and bucket functions.
The reference specification pairs a 2,000 kg rated payload with a 1.0 m³ bucket. Buyers should confirm loose material density, fragmentation and expected fill factor because bucket volume does not by itself determine the permissible load per cycle.
The published overall width is 1,300 mm, supporting access to comparatively narrow underground routes. Mine planners should still check bucket width, articulation sweep, turning radii and required wall clearance across the complete loading and haulage route.
The brochure lists 45 kN maximum breakout force, 50 kN maximum traction and travel speed up to 8 km/h. Actual performance depends on payload, gradient, road condition, tire grip, material fragmentation and operating practice.
The matching WJ-1 brochure lists a Deutz D914L04 engine rated at 58 kW, paired with a Danfoss T90 pump, Sauer MV23 motor and DLWJ-1 transfer case. Confirm the final engine, transmission components and emission configuration for the destination market in the technical offer.
The front and rear frames articulate through a published 38° steering angle. Hydraulic joystick control is used for steering and for boom-and-bucket operation, reducing the number of separate manual controls during repetitive loading cycles.
Published features include four-wheel drive, combined service and parking braking, warning lights for oil temperature, oil pressure and electrical conditions, a suspension seat and front/rear LED driving lights. The final quotation should define the complete brake architecture and operator-protection configuration.
The brochure lists engine fire suppression, automatic lubrication, remote control, side-dump bucket, bucket teeth, tire chains and a flashing beacon as options. Availability and compatibility should be confirmed for each ordered configuration.
Check these items before selecting the loader:
The available drawing shows turning geometry, but the two published overall lengths are not fully consistent. Submit the mine profile and request a configuration-specific dimension drawing before purchase.
The WJ-1 brochure lists four-wheel drive, combined working and parking brakes, system warning lights and an exhaust purifier with silencer. These features do not replace a mine-specific risk assessment or commissioning procedure.
Before operation, confirm operator protection, brake testing, articulation locking, raised-boom support, emergency steering, fire protection, towing and recovery points, isolation procedures and any remote-control safeguards. Daily checks should cover fluids, brakes, tires, bucket wear, articulation points, hoses, lights and alarms.

It is an underground LHD loader for loading and short-distance haulage of broken ore or waste in narrow workings. Typical discharge points include ore passes, stockpiles and underground trucks.
The reference specification lists a 2,000 kg payload and 1.0 m³ bucket. Bucket selection should be checked against material density and the rated payload limit.
The machine is published as 1,300 mm wide and 2,000 mm high. Required roadway size must also account for the bucket, articulation sweep, turning geometry, wall clearance and local safety rules.
The matching brochure lists a Deutz D914L04 rated at 58 kW. The current webpage lists a different Deutz engine and rating, so the ordered engine and emission package must be confirmed in writing.
Yes, remote control is listed as an option. Confirm controlled functions, range, communications, emergency stops, fail-safe behavior and operator-training requirements before ordering.
Send the roadway profile, turning constraints, gradients, haul distance, material density, fragmentation, target production, discharge interface, ventilation limits, destination country and required options.
