Conveyor pulley standard Background The traditional conveyor pulley typically has a through shaft on bearings supporting a lagged drum. Brexit An open space, not exceeding four (4) inches in width, may be left between the outside edge of the disk and the rim of the wheel if desired, to facilitate turning the wheel over. xref Where suspended counterweights are used and not guarded by location, they shall be so encased as to prevent accident. Material trapped in this location can allow the belt to slip against the pulley, causing the non-carrying underside of the . The driving point of all friction drives when exposed to contact shall be guarded, all arm or spoke friction drives and all web friction drives with holes in the web shall be entirely enclosed, and all projecting belts on friction drives where exposed to contact shall be guarded. Conveyor designs range from very small dual-belt conveyors used to move printed circuit boards through electronic board-stuffing machines to pneumatic conveyors moving pelletized plastic from storage silos to injection moulding machines to massive troughed-belt mining conveyors moving hundreds of tons of ore a minute. Pulley is also used to guide a cable or exert a force and it changes the direction of force, making pulling down easier than lifting up. Workers are most at risk from falling objects when standing or working: To prevent injury from flying debris, use safety glass, goggles, face shields, etc., where machines or tools may cause flying particles; and always inspect tools, such as saws and lathes, to ensure that: The protective guards are in good condition and firmly attached.
