Siton WJ-4 LHD loader is a high-efficiency machine specifically designed for loading, hauling, and dumping operations in small mines. It is mainly used for loading broken materials after blasting or cutting, and suitable for challenging underground working sites such as short-distance transport, narrow working spaces, low roof clearances, and muddy roadways. The whole machine is compact, flexible and efficient. The bucket volume is 4m³ and loading capacity is 10t. It is suitable for drifts with a cross‐section at least 4m wide and 4m high. The combination of compact size and superior performance is an ideal choice for improving the productivity of drifting and stoping operations.

Features and benefits

1.Safety

Siton WJ-4 underground loader features a full set of safety systems, including spring-applied, hydraulically-released (SAHR) brake and the combination of parking and emergency functions, ensuring reliable stopping in emergency. Door interlock: applies brakes, blocks steering and bucket/boom movement when door opens.Its canopy is ISO ROPS and FOPS certified. Radio Remote Control（RRC）is also available as an option. Standard-equipped LED lights improve visibility and help to avoid the loader colliding with walls, other equipment, or personnel.

2.High Efficiency

Siton LHD features an advanced diesel engine that delivers high torque at low rpm, strong power and stable operation. Its drive system features a hydrostatic CVT (continuously variable transmission) consisting of the variable-displacement pump and variable motor. This configuration ensures high-efficiency power transmission and low energy consumption and delivers continuous and reliable power even in complex underground working conditions.

3.Flexibility

WJ-4 adopts a central articulated structure between its front and rear frames, combined with a swing linkage mounted on a slewing bearing and four-wheel drive. This design ensures exceptional passability and steering precision in narrow drifts. The fully hydraulic power steering system reduces operator workload and enables agile maneuvering even under harsh underground conditions.

4.Maintenance

All daily maintenance can be performed from the ground. The equipment structure is compact and reasonable, and the layout of key components is clear, which facilitates quick positioning and troubleshooting. The accessories are highly universal and easy to replace, which shortens the maintenance cycle and further reduces the operating cost and manpower input.

5.Low Emission

The equipped diesel engine complies with the China III emission standards, adopts advanced combustion control technology and efficient emission treatment system, can effectively reduce exhaust emissions, to meet environmental requirements. Highly efficient and reliable exhaust purification system can reduce harmful gas emissions and improve air quality, especially suitable for drifts with poor ventilation.
