Abstract

Apparatus is disclosed for controlling the position of a mineral mining machine such as a plough, movable along guide means such as a scraper-chain conveyor with a guide on one side. The apparatus employs piston and cylinder units coupled between the guide means and connecting devices pivoted to the guide means. A ball-and-socket joint is provided between each of the units and the associated connecting device. Elongate beams are interconnected at one end and are mounted via a head piece and a swivel joint to each connecting device. These beams are pivoted and guided at their other ends on roof support structures so that the units can operate to tilt the guide means about the pivot axes between the connecting devices and the guide means to thereby control the position of the machine.
