Compact, agile, and high-torque underground diesel load-haul-dump (LHD) equipment tailored for rapid deployment across Paris metro extensions and civil excavation sites.
Navigating the complex underground civil engineering, metro tunneling networks, and quarrying demands across Île-de-France.
The Paris metropolitan area, anchored by the Île-de-France economic powerhouse, represents one of Europe's most intricate and demanding subterranean engineering landscapes. With mega-scale infrastructural developments such as the Grand Paris Express—the largest transport project in Europe spanning over 200 kilometers of new automated metro lines and 68 stations—the requirement for high-reliability, low-emission, and agile underground diesel loaders (LHDs) has surged dramatically. Subsurface contractors, tunnel boring backup teams, and underground civil utility developers in Paris require heavy machinery that couples robust mucking capability with stringent environmental and safety compliance.
Beyond modern mass-transit expansions, the historical geology of the Paris Basin—rich in subterranean limestone quarries, gypsum extraction zones, and deep-level utility galleries—presents distinct operating challenges. Underground loaders operating in these confined Parisian environments must deliver unmatched articulation, low turning radiuses, high breakout force, and dependable exhaust purification systems (such as DOC+DPF configurations) that comply with strict French and European atmospheric safety standards for underground workers.
Engineered with optimized center-hinge oscillating articulation, allowing our diesel loaders to maneuver seamlessly inside tight Parisian cross-passages, gallery excavations, and utility conduits.
Fully compliant with European occupational safety directives, equipped with spring-applied hydraulic-release (SAHR) multi-disc wet brakes and heavy-duty protective operator canopies.
Powered by variable displacement pumps and motors from premier global brands like Rexroth, Sauer, and Eaton, ensuring superior hydraulic efficiency and low maintenance downtime.
Pioneering Trackless Underground Mining & Tunneling Equipment Manufacturing Since 2012.
Shandong Derui Machinery Co., Ltd. was founded in 2012 and is located in Weifang, Shandong Province, known as the "Kite Capital." Derui is a high-tech enterprise specializing in trackless mining equipment, integrating R&D, manufacturing, sales, and service. Its main products include underground loaders, mining trucks, scaling jumbos, and multi-purpose utility vehicles. The company is equipped with a comprehensive hydraulic pump and motor testing platform, capable of undertaking maintenance and debugging for pumps and motors from brands such as Sauer, Eaton, and Rexroth. Since its establishment, we have focused on the production and R&D of trackless equipment for underground mining. We are committed to developing into an internationally renowned manufacturer of mining machinery and equipment, providing high-quality products and excellent services to a growing number of customers.
Currently, the company has over 200 employees, including a technical R&D team of more than 50 professionals. We have a comprehensive overseas market service team comprising sales personnel and after-sales support staff. Additionally, we have established branch offices in regions such as Zambia and Russia to ensure the quality and timeliness of our overseas services.
Delivering high-productivity solutions with lower total cost of ownership (TCO), uncompromising operator safety, and responsive technical support.
Derui focus on product leadership, service, cost, safety and efficiency will enable us to devote ourselves in the mining industry. We will continuously invest in human resource, machining equipment and advanced production equipment, after-sales service abilities and thus help our customers to solve mining’s toughest challenges.
Our factory-grade testing platform guarantees optimal calibration for high-end hydraulic components (Eaton, Rexroth, Sauer), minimizing on-site failure rates during critical tunneling cycles.
Optimized boom kinematics and heavy-duty load-sensing hydraulics allow rapid bucket filling and high-speed tramming, substantially reducing cycle times per mucking shift.
Backed by an overseas technical team and specialized regional support networks, Derui ensures rapid spare parts logistics and professional diagnostic services across Europe.
Tailored heavy machinery solutions built to excel in diverse urban civil engineering and mineral extraction operations.
In deep tunneling operations such as the Grand Paris metro extensions, traditional surface excavators cannot maneuver within narrow shaft bottoms or auxiliary cross-passages. Derui diesel LHD loaders—from ultra-compact 0.6 m³ models up to heavy-duty 4.0 m³ and 6.0 m³ units—provide the low-profile agility required to clear blasted rock, tunnel boring machine (TBM) backup spoil, and shotcrete rebound efficiently.
France possesses historical and active underground quarrying sites supplying raw materials for construction and historic preservation. Our underground diesel loaders are constructed with reinforced chassis frames, wear-resistant Hardox bucket cutting edges, and high ground clearance to handle jagged rock and steep gradients up to 25% with ease.
The modernization of storm-water retention tunnels and deep sewage collector networks around the River Seine requires machinery that can operate safely in damp, restricted underground spaces. Derui equipment features corrosion-resistant wiring, IP67 electrical enclosures, and hydraulic failsafe systems that ensure operator safety in saturated conditions.
As a direct manufacturer, Derui offers customized machine adaptations for European contractors, including remote radio control systems for hazardous unbolted headings, centralized automatic lubrication systems, and specialized exhaust water-scrubber systems for ultra-confined work headings.
