Abstract: In a device on hoisting machinery for automatically controlling the movem of a load carrier and for steadying the pendulum-type motion of a load suspended from the load carrier, a signal transmitter is provided for controlling the movement of the load carrier traction motor by means of a selected substantially cosine-shaped load carrier acceleration signal (b.sub.K). In such control a reduction is obtained of the acceleration time interval and braking time interval (T), respectively, at a selected maximum pulling force of the load carrier traction motor, and it is possible to keep the pulling force constant. The load acceleration (b.sub.L) follows a cosine curve.
