Abstract

The equipment allows the placing of hydraulic props as used in mining from a distance. It comprises a mobile machine (2) with an extensible boom (3) and a source (5) of hydraulic fluid under pressure, connected by a flexible hose (6) to the inlet (7) of the prop (1) to be placed in position. Brackets are provided on the prop to allow engagement by the machine boom, so that it can be installed in a vertical position. Each prop can have a collar (19) fixed to its base portion, and on which there pivots on a transverse axis a component (18) engaged by the end of the extensible boom, typically in the shape of a conical cap.
