FIELD: construction.
SUBSTANCE: invention relates to structural elements of cranes. Electric drive for movement with restriction of swinging of load comprises an acceleration sensor along three axes located on suspension mechanism, and a coordinate computer. Output of operator panel is connected to first input of control system. Output of acceleration sensor along three axes is connected to input of coordinate computer, and output of coordinate computer is connected to second input of control system. Output of torque sensor is connected to third input of control system. Output of control system is connected to input of voltage converter, which is connected to windings of asynchronous motor. Shaft of asynchronous motor is connected to suspension mechanism and torque sensor. Acceleration sensor on three axes is mounted on suspension mechanism.
EFFECT: technical result consists in limiting load swinging during movement.
