vehicle for the development of mines and tunnel construction

摘要

The working unit, esp. an installation frame, used for conveying and installing gallery support profile units, is incorporated in a vehicle used in providing support in pit and/or tunnel structures. The vehicle is in the form of a motor truck section with at least one axle, and a work truck section coupled to the front of this. The latter comprises at least one wheeled axle and a chassis frame with a hoist rod linkage unit swivelling on it. The front of this device supports a turning and tilting hinge, bearing a guiding device on which the working unit slides in a horizontal plane transversely and lengthways to the vehicle.
