Introduction to the 4 m³ Underground LHD Loader
Jan. 09, 2026
The 4 m³ underground LHD (Load-Haul-Dump machine, often referred to as a 4 m³ underground LHD) is a special underground mining loading and transportation equipment with a rated bucket capacity of 4 cubic meters. It is mainly used for loading and transporting ore and waste rock in underground non-explosive environments. The mainstream type is diesel-driven, with a rated load of 8–10 tons. It features articulated steering, four-wheel drive, compact flexibility, and safety reliability.

Underground loader Application
Suitable for underground roadways of metal mines and non-metal mines without explosive gases, as well as small tunnel projects.Adapts to working environments with roadway width ≥ 2.5 m and cross-section ≥ 4×4 m, especially suitable for medium and small mines or branch roadways of large mines. It can be matched with 10 t-class underground mining trucks to form an efficient loading-transportation cycle.Optional remote control system for high-risk stopes or unmanned working faces to reduce personnel exposure risks.
