Overview
The WX14LPE is a 14-tonne tethered-electric load–haul–dump (LHD) designed for low-profile underground industrial minerals operations. Formerly SLP-14E, it pairs a compact, 2.02 m cabin profile with a direct electric traction system, engineered cable management and components rated for continuous, zero-local-emission operation in demanding drift conditions.

Key benefits

• Power across cycles: 172 kW continuous traction power and 450 kW peak for strong muck pile penetration and acceleration.
• 14 tonne payload: Sized for high productivity in industrial minerals extraction.
• Smart cable handling: Controlled spooling reduces stress, twisting and safety risks to extend cable service life.
• Low‑profile geometry: 2.02 m cabin height for reliable navigation in low drifts and headings.
• Hydraulic efficiency: Load-sensing hydraulics reduce oil temperature and energy loss for consistent performance.
• Durable construction: Welded steel frames and heavy-duty components designed for prolonged operation and lower life-cycle maintenance.
• Operator-focused controls: Three-pedal layout and intuitive controls enabling smooth, stepless speed control for precise driving and loading.
• Zero local emissions: Tethered-electric power reduces heat and ventilation demands underground.
• Ergonomic safety cabin: Hammer glass windows, adjustable pedals and swiveling seat to support operator safety and comfort.
