Abstract: The invention concerns a conveyor belt arrestor, primarily for use with inclined conveyor belts, which operates to arrest the belt in the event that the belt breaks. The arrestor (10) of the invention has a frame (16) which is mounted in use to fixed structure of a conveyor belt installation. The frame includes a reaction member in the form of a beam (16.3) located above the top run of the belt (12). A wedging structure (18, 34, 44) is located beneath the top run of the conveyor bell and is mounted for swinging movement in a vertical plane relative to the frame. A torsion spring (42) is tensioned in use to apply a rotational bias to the wedging structure in a direction to swing it upwardly in the event of the belt breaking and belt tension being lost. This lifts the top run (12.1) of the belt towards the reaction member (16.3) such that the top run of the belt is trapped between the wedging structure and the reaction member by a wedging action that prevents movement of the top run of the belt in a direction opposite to its normal direction of forward travel.

Abstract: Conveyer belt braking apparatus comprises an idler roller (10) rotatable about an axle, and a brake member (40) mounted adjacent the idler roller and movable relative to the roller between a first, inoperative position adjacent a belt supported by the roller and a second, braking position against the belt. An operating mechanism (26, 28) is arranged to sense the direction of rotation of the roller and to move the brake member from the first, inoperative position to the second, braking position when the direction of rotation of the roller reverses in use. Preferably the mechanism includes a clutch bearing (26) that engages to move the brake member from the first inoperative position to the second, braking position thereof when the roller reverses direction.
