TECHNICAL FIELD

[0001] The utility model relates to cable collection technical field, concretely relates to a direct current disc cable collection tool for crane. BACKGROUND

[0002] As the core hoisting equipment of many industries, the crane needs to rely on the coordinated cooperation of the cart running system, the trolley running system and the lifting system to complete various hoisting operations in the workshop. Among them, the double-hook bridge crane is generally equipped with a hoist beam, and a direct current cable is used to power the disc on the hoist. The direct current cable is connected with the junction box of the hoist beam through the cable drum on the trolley to realize the cable winding and unwinding function.
