GHH Fahrzeuge – LHDs

GHH provides Load Haul Dumpers (LHDs) for operations in both hard rock and soft rock mining. In addition to LHDs with diesel engines our portfolio also includes electric powered LHDs, Super Low Profile (SLP) LHDs, used for low profile reef mining as well as flameproof/permissible LHDs. Besides safety the key design criteria for our LHDs are ergonomics, maintainability, availability and efficiency.

DIESEL LHDs

GHH Diesel LHDs are particularly compact with an optimal operator’s position. The lateral arrangement of the operator seat guarantees optimal views for forward and backward tramming. The capacities of the GHH LHDs are ranging between 3 to 21 tons, respectively from 1.5 to 14 m³ (1.3 to 18.3 yd³). The LHDs are globally used in underground mining, tunneling, hydro-power and other civil construction projects. The "plain-tech" LHDs are characterized by robustness and the "high-tech" LHDs additionally by our efficient hydrostatic drive train (EDS) combined with best in class exhaust after treatment. Safety, ergonomics and maintainability are some of the key features of our design.

Super Low Profile LHDs

GHH Fahrzeuge has the largest portfolio of "super low profile" - LHDs (SLP), with capacities ranging between 3 and 21 tons. The long-term experience of GHH Fahrzeuge in low profile applications in the platinum and chrome mines in Southern Africa as well as in European potash mines is reflected in the design of our vehicles. Our vehicles are optimized for such special conditions and enable a highly-efficient selective extraction in low profile room-and-pillar mining. Also in this range safety and maintainability are major topics the designing department of GHH takes care of.

Electric LHDs

GHH offers electric LHD with capacities ranging from 10 to 21 tons. Furthermore, all electric LHDs are equipped with an active drum control which ensures an orderly winding, whereby a long service life of the cable is reached due to low tensile forces. The electric LHD offer particular advantages in underground applications through its emission-free drive and are therefore especially suitable for projects where ventilation is critical. Further advantages of the electric LHDs result from a low noise level. A constant torque and the resulting dynamics allow for more efficient loading of the muck pile. Furthermore, economic benefits result from a high reliability and a long life span of the drive components. This means fewer spare parts and lower maintenance costs and hence lower overall operating costs. The electric LHDs of GHH Fahrzeuge are equipped with the proven hydrostatic Efficient Drive System (EDS), which ideally complements to the electric motor running at a constant speed due to its continuous variable transmission. In connection with an intelligent monitoring system efficiencies are increased and consequently power consumption is reduced significantly. Minimized brake and tire wear as well as simple maintainability are main characteristics of this LHD class.

Flame Proof LHDs

GHH Fahrzeuge also manufactures Diesel LHDs for use in hazardous underground environments where explosive mine gases may occur. In addition to coal mining, there are also other deposits with such hazard potential (e.g. methane) in which only flameproof/permissible equipment may be used. Our flameproof LHDs are based on long-time proven vehicles and are equipped exclusively with high-quality explosion-protected components from renowned suppliers. Currently, we have the low profile multi-purpose SLP-5FP (Flameproof) and the LF-10Ex (explosionproof) in our product portfolio.
