The structural form of QY insulated bridge crane is basically the same as that of hook bridge crane,but in order to prevent the live equipment from being transmitted to the crane through the lifted objects during the working process,endangering the life safety of the driver,three insulation devices are set in the hook group,trolley frame and small wheel(or under the trolley track).The insulating materials are mostly epoxy phenolic glass cloth.It is suitable for factories smelting aluminum and magnesium.
