The WJ-3.0 LHD, with its compact design, powerful operational performance, reliable intelligent monitoring system, and environmentally friendly power solutions, provides an efficient and technologically advanced underground mining solution for narrow-vein mining. Its remote control and precise operation capabilities further help reduce mining dilution rates and improve overall economic benefits.
WJ-3.0 Narrow Vein Underground Loader Technical Overview
The WJ-3.0 is a compact underground loader (LHD) designed specifically for narrow vein and confined space mining operations. Its core design philosophy is to achieve efficient, precise, and reliable ore loading and hauling in extremely confined conditions through optimized structure, drive, and control systems.
I. Structural Design and Maneuverability
Articulated Steering System: Utilizing an innovative articulated frame structure with a large 40° steering angle, it enables flexible steering and U-turns in tunnels as small as 3.4m x 3.4m.
Compact Body: Optimized overall width and turning radius are key to its high maneuverability, significantly improving maneuverability and operating efficiency in narrow mines.
Ergonomics and Visibility: The rear-mounted cab layout, coupled with an ergonomically designed side-seat canopy, provides the operator with unobstructed, excellent two-way visibility, ensuring safe and precise two-way driving and operation.
II. Operating Performance and Powertrain
Optimized Working Mechanism: The enhanced geometry of the boom and loading frame is designed to provide an optimal digging force curve and efficient bucket fill rate, thereby optimizing loading efficiency.
All-Wheel Drive System: Equipped with four-wheel drive, the front axle is equipped with a zero-slip differential, and the rear axle is equipped with a limited-slip differential. This combination ensures effective driving force to all wheels in adverse road conditions, providing excellent traction.
Safe Braking: Equipped with the SAHR braking system (spring-applied, hydraulically released), this fail-safe system automatically applies the brakes in the event of a loss of hydraulic pressure, providing dual reliability for both the operating and parking brakes.
III. Intelligent Operation and Maintenance
Condition Monitoring System: An integrated automatic alarm system monitors key parameters (such as hydraulic oil temperature, oil pressure, and electrical system status) in real time, providing early warning of faults and assisting in maintenance decisions.
Optimized Operating Environment: The low-vibration cab design effectively reduces operator fatigue, improving comfort and efficiency during extended operations.
IV. Power and Environmental Protection
Power Core: Equipped with a German Deutz air-cooled turbocharged engine, it provides powerful power while optimizing fuel economy.
Emissions and Noise Control: Equipped with a Canadian ECS catalytic converter, it effectively reduces harmful exhaust emissions and controls operating noise, helping to improve underground air quality and the working environment, meeting environmentally friendly operation requirements.
