Products installed digging machine known as slag, slag stone is mainly used to solve the problem of loading 3 ~ 9m narrow tunnel boring time. Suitable for tunnel excavation, mining engineering, water conservancy construction and other engineering machinery and small section of diversion tunnel, mine slag (mine) machine, the machine is mainly used in the production of some of the narrow space to do business risk of non-explosive mine gravel soil collection and transport construction material loading. The main advantage of Wz series Cinder machine is absorbing foreign advanced technology developed for construction equipment slag roads, railways and hydropower tunnels, is independent with independent intellectual property rights, patents, products, electrical control mode hydraulic control, power systems for diesel-electric dual system, is a comfortable, high efficiency construction equipment. The aircraft from the mining unit, walking devices, rotary devices and conveying device composition, collection and transport functions into one, dual power system for diesel power in the hole when walking or working outside the cave, cave construction when using electric full hydraulic device, effectively less narrow cave, insufficient air, etc., with safety and environmental protection, high efficiency characteristics. Is essential for mining and tunnel in mining and slag advanced equipment, is labor and other mechanical alternative.
