DERUI offers a range of underground equipments to meet your high production demands and lower your cost per ton. DERUI produces vehicles for use in tight spaces and low altitudes must be extremely compact in size and must have an optimal driving position. The arrangement allows the driver side of the vehicle good visibility when driving forward and backward. Environmentally compatible is necessary for all sorts of field operation, so we mount air or water cooled diesel engines fitted with catalytic converters. Equipments manufactured by DERUI are available with electric motors too.
Electrical driven equipments present the advantage of zero exhaust emission and consequently ideal for mining projects where fresh air is top priority.
