This standard applies to cast wire rope pulleys (hereinafter referred to as pulleys) with rolling bearings and no inner sleeves that require strict sealing within the scope of the crane movable pulley block.
Pulleys in this standard can also be used in other pulleys in wire rope transmission, such as fixed pulleys or other load-bearing parts other than movable pulley blocks.
