ABSTRACT:
A chain, a chain wheel and a chain transmission for a lifting gear in accordance with the present invention increases the dynamic resistance of a round steel chain that is primarily intended for use in combination with a lifting gear. The chain members (5, 6) are locally deformed plastically in the area of their braces (9, 10) so as to form flat lateral zones (11).
