A cable reeling drum is a cylindrical spool or reel used to store and unfurl cable on a gantry crane. It is a vital component in the crane’s electrical system, as it helps to power the movement of the crane and keep the cables out of the way while in operation. The drum typically houses a number of cables, which are then connected to the crane’s power source. The drum also helps to guide the cables as they are being reeled in or out. The size and type of cable reeling drum needed depends on the size and weight of the gantry crane, as well as the type of application it is used for.
