WPZ-55/50L Roadway Repair Machine is a repair equipment for underground mines. It is mainly used for roadway leveling operation of the coal mine, which could also be used for crushing, slagging-off and loading of gangue in underground cavity operations such as mine roadway, highway (railway) tunnel, etc.


■ Application conditions

The roadway shall be not less than 1.5m high and 2.0m wide before leveling;

Protodyakonov coefficient f of roadway floor rocks shall be ≤12.

The depth of water accumulated in the roadway shall be lower than the track.

■ Characteristics of repair machine

Featuring narrow body and good disintegration, it facilitates the underground handling and transportation. At the inlet, the working mechanism is equipped with breaking hammer with high crushing efficiency, so that the labor intensity will be greatly reduced. The scraper transporter in split structure features reliable transportation, easy dismantlement and large transport capacity and is able to turn. It has high degree of automation and automatic cable winding and releasing function able to solve repeated movement of cables during construction of the repair machine. It is equipped with a spray device at the inlet to reduce dust and inhibit explosion, which renders a good operation environment.

The hydraulic system adopts the LUDV control (load pressure independent flow distribution control), so that the operation is flexible, easy and highly reliable.
