Explore our prime high-capacity underground diesel LHD loaders built to conquer tough gradients, narrow drifts, and intensive production schedules in Antofagasta, Calama, and O'Higgins regions.
Chile stands as the world's undisputed premier copper producer, alongside expanding gold, silver, molybdenum, and lithium extraction sectors. As historical open-pit deposits mature and stripping ratios become economically challenging, iconic Chilean mining centers like Chuquicamata, El Teniente, Salvador, and Mantos Blancos have aggressively transitioned or expanded into massive underground block-caving, panel-caving, and sub-level stoping methods.
Underground extraction in Chile imposes distinct, rigorous demands on trackless mobile machinery. Operating elevations frequently exceed 2,500 to 4,500 meters above sea level in the high Andes, where thin atmospheric oxygen causes severe internal combustion derating and cooling challenges. Furthermore, strict environmental and occupational health safety guidelines dictated by SERNAGEOMIN mandate ultra-low diesel particulate emissions, resilient hydraulic response, and FOPS/ROPS-certified structural integrity.
Our wholesale factory operations supply specialized LHD (Load-Haul-Dump) machines custom-configured for Chilean underground geology, combining high power-to-weight ratios, robust hydrostatic drivetrains, and easy-maintenance modularity to deliver maximum availability and the lowest cost-per-ton mucking performance.
Integrated with altitude-compensated turbocharged diesel engines and electronic fuel injection systems, our LHD loaders prevent thermal overloading and power drop-off in high-elevation Chilean drifts.
Utilizing genuine Rexroth, Sauer-Danfoss, Eaton, and Kessler drivetrain assemblies, rigorously tested on automated hydraulic benches to ensure rock-solid continuous duty cycles.
From ultra-compact narrow-vein veins in central Chile to heavy drawpoint production loading in northern mega-mines, our LHD loaders cover the entire mining spectrum.
Small-scale and mid-tier polymetallic mines in Coquimbo and Atacama rely on the DRWJ-0.6, DRWJ-1, and DRWJ-1.5 loaders. Featuring compact chassis profiles (width under 1.3m to 1.6m), articulated center steering, and tight turning radii, these machines cleanly navigate narrow heading profiles with minimal rock dilution.
For massive porphyry copper deposits operating under panel and block caving schemes in O'Higgins and Antofagasta, our DRWJ-3, DRWJ-4, and DRWJ-6 models supply continuous heavy-duty drawpoint extraction, direct truck loading, and high-volume transfer to underground primary gyratory crushers.
Rapid access development requires rugged ramp climbers. Our diesel LHD series features high-torque multi-speed powershift transmissions, four-wheel drive traction control, and multi-disc SAHR (Spring Applied Hydraulic Released) enclosed wet brakes to conquer steep decline slopes up to 25% gradient safely.

The Chilean mining sector is a pioneer in adopting automation, decarbonization, and smart remote operations to achieve Zero-Harm and high production KPIs.
In high-stress rock environments prone to rockbursts or seismic occurrences in deep Andean mines, operator safety is paramount. Derui LHD machines offer optional line-of-sight radio remote control and long-range video-guided tele-operation systems. Operators can navigate the loader, muck drawpoints, and dump into trucks or ore passes from surface control centers, totally removed from geotechnical risk areas.
Underground ventilation costs constitute up to 40% of deep mining operating energy budgets in Chile. Our latest diesel LHD series features high-efficiency common-rail engines equipped with closed-loop Diesel Particulate Filters (DPF) and DOC catalysts, drastically reducing NOx and particulate emissions, aligning with strict environmental standards while minimizing ventilation overhead.
Equipped with advanced CAN-Bus electronic monitoring architectures, Derui underground loaders deliver real-time data on hydraulic oil temperatures, brake pressure integrity, transmission parameters, and fault codes. This facilitates predictive maintenance strategies, enabling Chilean fleet managers to prevent catastrophic downtime and optimize life-cycle parts logistics.
Every Derui cabin is certified to international ISO FOPS/ROPS safety standards, offering enclosed, air-conditioned, and soundproof environments. Ergonomic pilot joystick controls reduce operator fatigue over continuous 12-hour shifts common in Chilean mining schedules.
