Abstract

The invention discloses a crane electrical control device, which is characterized by comprising a remote control transmitter, a remote control receiver and a control box body, wherein the remote control receiver outputs signals to a PLC input end, and the PLC controls operation of the motor through an alternating current contactor. According to the crane electrical control device, an operator does not need to stand near the crane for operation, safety of the operator is improved, corrosion of chemical gases is reduced as the electrical control box is moved indoors, corrosion on the electrical component by gases can be reduced, electrical fault is thus reduced, the maintenance cost is saved, the crane is controlled in a remote control mode, and the operation is convenient and safe. The invention also relates to an operation method for the crane electrical control device.

Description

technical field [0001] The invention relates to an electrical control device for a crane, in particular to a remote-controlled electrical control device for a crane with safe operation and few electrical failures; the invention also relates to an operation method for the electrical control device for a crane. Background technique [0002] At present, the known electrical control boxes for cranes are all installed on the housing of the lifting motor, and the traditional AC contactor is used to interlock the electricity and machinery. This method of operation is for lifting equipment such as cranes, because the handle line restricts personnel to operate at a place very close to the lifting object, which is extremely dangerous and unsafe accidents often occur; and in chemical workshops, corrosion is serious, and electric control The box above is corroded by gas for a long time, and electrical components often break down. In severe cases, the motor burns out, which affects produ...
