The DALI WJ-4 is a 10-ton diesel underground LHD loader for production loading and short underground haulage. Its reference configuration combines a 4.5 m3 bucket, 242 kW Cummins engine, powershift drivetrain and 2.427 m machine width. It is intended for mines that need higher tonnes per cycle without moving to the largest LHD class.

The WJ-4 load haul dump machine is positioned between medium-capacity loaders and larger production units. Its 10-ton payload suits repeated transfer of broken ore or waste from drawpoints and headings to ore passes, stockpiles or underground trucks.
The matching product brochure is used as the technical baseline for this draft. Because the live webpage contains a different bucket, dimensions, powertrain and performance values, DALI engineering should confirm the active configuration before publication or quotation.
The reference specification pairs a 10,000 kg rated payload with a 4.5 m3 bucket. Bucket selection should be checked against loose material density, fragmentation and fill factor so that volume does not drive the machine above its rated payload.
Published reference values include 190 kN breakout force, 230 kN maximum traction and four forward/reverse travel ranges up to 24.5 km/h. Actual results depend on road condition, gradient, tire choice, material and operator practice.
The brochure lists a Cummins QSL9 engine rated at 242 kW, a DANA C5502-263 torque converter, R36425-10 electronic powershift transmission and DANA 20D POSI-STOP axles. Confirm engine and emissions availability for the destination market.
The reference build lists a Q460 articulated frame, HARDOX 600 bucket and 18.00R25 L-5S radial tires. These details matter where impact, abrasion and sharp rock influence structural life and tire cost; material grades and tire supply should be verified in the final offer.
Wet multidisc POSI-STOP brakes act through separate circuits, with spring-applied braking for loss-of-pressure protection. The brochure also lists a master power isolator, emergency stop, articulation lock and emergency brake-release pump.
The reference configuration includes forward and reverse cameras, a 7-inch display, warning and fault information, work lights, beacon and reverse alarm. Confirm the final cab, visibility package and site-specific alarm requirements.
Multiple service doors, grouped monitoring, automatic lubrication and clearly defined consumables can reduce routine service effort. Ask for the maintenance schedule, filter list, wear-parts recommendation and commissioning scope with the quotation.

Final standard equipment and option compatibility must be stated in the signed technical offer.
Yes. The matching brochure lists a rated tramming capacity of 10,000 kg. Actual material volume per cycle must remain within that payload.
The brochure lists 4.5 m3, while the current webpage lists 4.0 m3. DALI should confirm the current standard bucket and available density-matched alternatives.
Send the roadway profile, tightest turn, gradient, haul distance, material density, fragmentation, truck or ore-pass dimensions, tonnes-per-shift target, ventilation limits and destination country.
Remote control is listed as an option. Confirm operating range, controlled functions, emergency stops, communications and the mine’s remote-operation procedure.
