How to control a crane

A bridge crane is a bridge that runs on an elevated track. A bridge-type crane is also called an overhead crane. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated tracks on both sides. The trolley runs transversely along the tracks laid on the bridge frame, forming a rectangular working boundary, the space under the bridge can be fully utilized for lifting materials without being hindered by ground settings.

Operating conditions of the bridge crane: Hook lifting and lowering operation: the hook is lifted and lowered by dragging the steel wire through the motor. The forward and reverse operation of the motor will determine the movement direction of the hook. During operation, the limit boundary of the steel wire needs to be considered; trolley Sequential operation control: The sequential movement of the crane carrying trolley is also driven by the electric motor, and it is not allowed to cross the limit positions on both sides of the crane during the movement.

When the crane is in the moving state, bells and warnings should be given, and indicator lights should be displayed in the cab at the corresponding limit position during operation; crane up and down operation control: the crane moves up and down. Ffl drives the motor to drive the entire car body on the track. The movement boundary of the up and down movement should be controlled at a certain distance between the track and the two end points to ensure that the device will not deviate from the track.
