CONVEYOR IDLER

摘要

This invention relates to a brake mechanism 10 for a substantially hollow conveyor idler 12 which is rotatable about an idler shaft 14. The brake mechanism comprises a brake guide 20 which is secured to the idler shaft. The brake guide defines an outer surface 26 which is adapted to fit rotatably within the hollow conveyor idler 12. The outer surface includes at least one recess thereon. The brake mechanism comprises further a brake element 40 which is located in the recess, between an inner surface of the conveyor idler and the brake guide 20. The brake element is movable in the recess, between a first position and a second position. The recess is shaped such that in the first position the brake element is received substantially within the recess and in the second position the brake element protrudes from the recess and engages the inner surface of the conveyor idler.
