Abstract
Apparatus for controlling the position of a mineral mining machine, such as a plow, guided for movement along a guide, employs inclined piston and cylinder units connected between connectors at the ends of elongate beams or rods guided on support units and brackets on a conveyor supporting the guide. The units have cylinders coupled via ball-and-socket joints to the brackets and these joints are disposed above pivot joints linking the conveyor to the connectors. The piston rods of the units are received in pockets in the connectors and flexibly and pivotably coupled thereto.
