Abstract

The mine roof support mechanism is for a mining machine (30) with a swinging arm (32) carrying a rotary cutter (33) to convey it over a curved path. It includes a pair of arms (20), one each side of the cutter. Each arm carries a plate (15) at the end shaped to carry a transver roof support (40). These arms are mounted on a cross member (13") mounted on the machine frame. Each arm (20) consists of a system of levers (21, 22) so that it can be extended and retracted by a set of actuators (17, 23). These levers are attached at the bottom to side plates (14) mounted on a spindle (18) which slopes rearwards, fastened on the cross member (13"). This cross member can be moved backwards or forwards by cylinders (12) below. The pivot support also allows the arms to tilt sideways.
