Abstract
The invention concerns a chain pulley block with a chain wheel for positive-locking transmission of the lift force to the chain and a chain guide arranged in the region of the chain wheel, for guiding the chain, especially a round-link chain, on the chain wheel. In order to make it fast, easy and inexpensive to replace wearing parts, such as chain (3), chain wheel (4) and chain guide (2), it is proposed that the chain guide (2), the chain wheel (4) and the chain (3) be assembled into a structural unit (1), which is removably fastened to the chain pulley block (7).
