    摘要: An extending prop for underground and tunnel construction, comprising, an outer tube having a closed bottom end, an inner tube telescopically slidable in the outer tube and having a closed top end, and a mechanical locking device adapted to fix the relative positions of the inner and outer tubes. A hydraulically actuated flying piston is arranged in the outer tube and is separated from the inner tube. The piston is adapted to extend the inner tube upon actuation by hydraulic pressure. The piston divides the prop into a bottom chamber enclosed by the outer tube and a top chamber enclosed by the inner tube. A first filling connection is arranged on the outer tube for filling the bottom chamber with a pressure medium for actuating the piston. A second filling connection is arranged on the inner tube for filling the top chamber. The prop is fillable with construction material through the second filling connection over its entire length by displacement of the piston toward the bottom end of the the outer tube.

    摘要: There is a support for underground mining and tunnel construction, comprising an outer tube and an inner tube, which can be pushed into each other in a telescoping manner. A piston acted upon by a hydraulic pressure medium is located in the outer tube. This piston, when acted upon by pressure, acts on the inner tube to cause an extension. The outer tube and the inner tube can be fixed on each other by means of a mechanical locking device.
