FIELD: transport.
SUBSTANCE: invention relates to the method of crane control. In crane operation, section of cable rope 13 connected with crake hook is controlled by friction drive wheel, redundant cable rope is wound in several layers on accumulation drum using two mechanisms. First mechanism is intended for drive wheel. Second mechanism is intended for accumulation drum. One of said mechanisms is controlled by speed setting instruction wile another one is controlled by torque setting instruction.
EFFECT: longer life of cable rope.
