Currently, most gantry cranes use cables and are powered by synchronous drag. For example, Chinese utility model CN220766315U discloses a gantry crane for prefabricated concrete parts, including a gantry frame and a guide rail on the inner side of the top of the displacement gantry frame. The guide rails are connected to the transmission There are a lifting equipment body and a sliding structure. The lifting equipment body is electrically connected to a cable.
