Method for stabilizing the movement of an articulated chain of a chain block, especially to prevent the formation of a resonance oscillation of the chain, and a chain block apparatus

The invention concerns a method for stabilizing the motion of an articulated chain of a chain block, especially to prevent the formation of resonance oscillation of the chain, in which an articulated chain is led across a polygonal chain wheel with non-uniform pitch, which is driven by an electric m...
