Support turning device with conical rollers and forged rails. Walking excavators are used in the mining industry in the extraction of minerals (coal, shale, ores of ferrous and non-ferrous metals, gold, raw materials for the chemical industry, refractories, etc.) by open pit mining.
Their purpose is stripping works with rock placement in the excavated space or on the side of the open pit. Excavators are capable of moving rock mass over long distances.
Partial or continuous loosening by blasting is required when mining hard rock. Excavators reliably operate at temperatures from minus 50° to plus 40° C.
