The position of the protective plate of the conductive sliding contact line of the bridge crane

The bridge crane used in enterprise production is a large-scale equipment that needs to be driven by electricity. In the operating range of the bridge crane, the trolley line is generally used as the power supply method, in order to ensure the safety of the bridge crane’s electricity use and the lifting Personal safety, hoisting machinery safety regulations require the installation of a protective plate device for the conductive sliding contact line of the bridge crane. The editor will introduce to you the positions of the conductive sliding contact line protective plate for the lower bridge crane.

According to the requirements of safety regulations, the following positions of bridge cranes should be equipped with conductive sliding contact line protection boards:

① When the driver’s cab is located at the end of the trolley trolley line, a protective plate should be set between the ladder leading to the crane and the platform and the trolley line;

②Under the end beam of the sliding line end of the bridge crane, a protective plate should be installed to prevent accidental contact between the spreader or the wire rope and the sliding line;

③For other cranes that use trolley wire, conductive trolley wire protection plates should be installed on the parts prone to electric shock;

④ When the bridge crane is arranged in multiple layers, the trolley line of the lower crane shall be equipped with a protective plate.

The purpose of setting the conductive sliding contact line protection board on the bridge crane is to isolate the sliding contact line and prevent electric shock accidents. The relevant units used by the enterprise must do a good job in the inspection and maintenance of the equipment to ensure the perfection of the protective board device.
