ABSTRACT:
An electric drive for the vehicle or traveling mechanism of a lifting appliance contains a control which controls the switching on of the mechanical brake and the switching of the motor current off and on again. In this case, there is provision, in the event of a changeover from a high traveling speed to slow maneuvering speed, for the mechanical brake to remain released until the maneuvering speed is approached. During this phase, the vehicle is decelerated solely by the internal friction and the rolling friction on the rail, in order to avoid inducing any or any additional load pendulum oscillation.
