Abstract
Apparatus for controlling the position of a mineral mining machine, such as a coal plough, guided for movement back and forth along a guide employs inclined piston and cylinder units coupled via ball-and-socket joints to brackets on a conveyor supporting the guide and to connectors which are pivotably connected to the conveyor. Assemblies have parallel elongate beams which are guided on roof supports and linked to the connectors. Each connector is of multi-part construction with a main skid resting on the floor of the working and connected to the conveyor and to the associated beams. A further complementary component fits onto the main skid and the parts of the connector have curved recesses which combine to form a socket for receiving a ball of the associated unit.
