Underground loader, professional named as LHD, load-haul-dump are mainly applied for underground mines. It also can be applied for railway, highway and water conservancy tunnel projects, particularly suitable for poor working conditions like narrow, low and muddy environment.
LHD includes two series here, one is diesel engine powered and the other is electric motor. The diesel loaders usually are equipped with DEUTZ low pollution engine which is very smart & flexible in the tunnel. The electric LHD has a 100 meters long cable, so it is not as flexible as the diesel LHD. However, the electric LHD has no pollution at all.
