Abstract

A mine support unit is arranged overhanging a face conveyor, and it has a swinging arm arrangement mounted on a sledge (2) at floor level, and carrying a large area roof supporting plate (6) at its end, and it has a horizontal actuator cylinder on the sledge, for adjustment towards and away from the conveyor. It has two 'L' shaped swinging arms (13) in an intermediate position between the linkage system (1, 10) carrying the roof support and a pair of actuator cylinders (4) further forwards, which raise and lower the roof support. Each 'L' shaped arm has a pivot point on the rear linkage and on a support (3) for the bottom of the first cylinder (4).
