The DALI WJ-6 is a 14-ton diesel underground LHD loader for high-volume production loading in roadways above 4.2 x 3.8 m. A 6 m3 bucket, 250 kW Cummins engine and 287 kN published traction place it at the large end of DALI’s conventional underground loader range.

The WJ-6 is intended for mines where the loading system, roadway and downstream truck fleet can use a 14-ton payload effectively. It loads broken ore or waste at drawpoints and headings, then trams it to a crusher, ore pass, stockpile or underground truck.
This is a capacity-led choice: access, road quality, ventilation and truck matching matter as much as bucket size. No matching WJ-6 PDF was found in the supplied files, so all values below come from the current webpage and require confirmation in the final technical offer.
The 14,000 kg payload and 6 m3 bucket increase tonnes per pass when material density and bucket fill are suitable. Check the actual loose density: a full bucket must not exceed the rated payload.
The published dumping height is 1,809 mm and maximum lift height is 5,327 mm. Confirm truck-body height and width, loader approach, discharge clearance, pass count and spillage control with scaled layout data.
Published maximum traction is 287 kN, breakout force is 224 kN and travel speed reaches 28.7 km/h. Route gradient, rolling resistance, corners, tire heat and braking constraints determine sustainable cycle performance.
The current page lists a Cummins QSM11 engine rated at 250 kW, with a DANA C8000 torque converter, DANA 6000 gearbox and Kessler D106 axles. Confirm the emissions package and exact component suffixes for the destination.
The machine is 10.644 m long and 2.7 m wide, with 42-degree articulation and +/-10-degree axle oscillation. Use swept-path checks rather than relying only on straight roadway width.
The webpage lists four-wheel multidisc wet brakes, spring-applied hydraulically released parking braking, front NO-SPIN and rear anti-slip differentials, alarms and exhaust purification. Confirm emergency steering, fire protection, cameras and protective structure in the quoted build.

Consider it when headings, turns, ventilation and downstream haulage can support a 14-ton loader and when higher tonnes per pass improve the overall production cycle.
The webpage states a tunnel size above 4.2 x 3.8 m. A site check must also include the 2.7 m body width, bucket envelope, turning sweep, ground clearance and mine-required safety clearance.
Divide usable truck payload by the safe tonnes carried per bucket, then allow for fill factor and density. DALI should verify practical pass matching for the selected truck body.
Ask DALI to define the cab/protective structure, cameras, fire suppression, emergency steering, automatic lubrication, alarms and isolation provisions in the technical offer.
