Abstract

Motor control facility for use with equipment, having at least one motorized horizontal movement, including the equipment a tension member, connectable to a load, to allow the equipment to lift a load, in order to move the suspended load, raised, horizontally from one position to another, characterized in that said motor control installation comprises adjustable speed electric motor means, to drive the equipment in a horizontal direction, a power supply to the motor, connected to said motor, including said power supply to the motor, regulating means for controlling said motor, in response to command signals, indicative of the desired performance of said motor, and feedback signals, a command source, coupled to said power supply to the motor, to procure the command signals, indicative of the desired performance of said motor, a source of first feedback signals, coupled to dich or power supply to the motor, and indicative of the current performance of said motor, a source of second feedback signals, which vary as a function of the movement of said tension member, relative to the vertical direction; and a device for coupling the second feedback signals to said regulator, to vary the rate of change of speed of the equipment in the horizontal direction, in response to the second feedback signals.
