First, steel cable chain soft lifting
Use copper towers or telephone poles to set the copper trolley wire in the air, and the weight is supported by steel cables to ensure that the horizontal copper trolley wire is fixed on the insulating porcelain bottle chain. Several copper trolley wires are placed horizontally with a spacing of about 300 mm. The copper trolley wire is The pulleys or counterweights are used at the ends to ensure that the copper tram lines are safely and reliably in horizontal tension and ensure the reliable power supply of the gantry cranes. (As shown below)
Second, horizontal load suspension hard lifting
The utility model uses a utility pole to set the copper trolley wire in high altitude and the weight is supported by a cross arm to ensure that the horizontal copper trolley wire is fixed on the insulated porcelain bottle clamp. Several copper trolley wires are placed horizontally with a spacing of about 300 mm. The end of the slide wire is used. The terminal overhanging device ensures that the copper tramline can be safely and reliably placed in horizontal tension to ensure the reliable power supply of the gantry crane. (As shown below)
