25 ton chain block
Chain block is used in most industrial applications as a chain. In fact, unlike electric hoist that use electric power, lifting with a manual crane is done manually by rotating a chain, and therefore it is a very suitable choice for lifting in areas where there is no access to electricity. A manual crane consists of a block, inside which a central shaft, bushing and bearing and several gears and sprockets work together to move the manual chain in a long length with low energy to move on the load steel chain. They transmit in a small amount but with high elasticity.
