Mid-large Underground LHD PX-WJ-3.0 | PX Series

Product Overview

The PX-WJ-3.0 is a mid-large underground LHD (load-haul-dump) machine engineered for large-section underground headings in metal and non-metal mines. It bridges loading and short-haulage duties, providing high breakout capability and dependable mucking cycles in decline drifts, access tunnels and production stopes. With a bucket capacity of 2.0–3.0 m³ and diesel or electric power options available by model, it suits mining contractors and mine operators seeking versatile, low-profile loading equipment. The unit is purpose-built for cramped underground layouts where productivity, maneuverability and serviceability determine overall material-handling efficiency.

Product Description

The PX-WJ-3.0 follows a low-profile design philosophy, allowing the machine to work safely in underground headings with restricted clearance while retaining the structural stiffness demanded by hard mucking duty. Heavy-duty hydraulic power configuration supports smooth bucket actuation and efficient material breakout across varied rock conditions. Because diesel or electric options are available by model, mine operators can match the prime mover to ventilation schemes and emission constraints without reworking the rest of the loading system.

For production, development and cleanup cycles in large-section headings, the PX-WJ-3.0 delivers reliable load-haul-dump performance, combining digging force with short-cycle maneuverability. Ergonomic operator interfaces, straightforward maintenance layouts and durable wear components are considered in the design to keep downtime low over long production shifts. The machine is typically integrated into fleets feeding crushers, transfer points or haulage systems, and its parameters can be adapted to site-specific loading conditions through configuration.

Technical Specifications

Applications

The PX-WJ-3.0 is suited to large-section underground loading, LHD haulage and cleanup duties in underground mines, development tunnels and civil excavation projects. It helps mine operators maintain high mucking rates while keeping the machinery footprint and emissions profile aligned with underground constraints. Electric configurations are especially relevant in ventilation-sensitive operations. By covering loading and short-haulage in one machine, the LHD reduces fleet duplication and lowers total cost per ton moved.
