Detailed introduction:
If there is electricity, use a wire to connect.
1. Steel strand chain soft lifting: Copper trolley wires are erected in the air using iron towers or utility poles, with steel wire ropes supporting the heavy objects to ensure that the horizontal copper trolley wires are fixed on the insulated porcelain bottle chains. Several copper trolley wires are placed horizontally, with a spacing of about 300 mm. The ends of the copper trolley wires are equipped with rollers or counterweights to ensure that the copper trolley wires are in a reliable horizontal tension state, guaranteeing reliable power supply for the gantry crane.
2. Cross-arm suspension type rigid suspension: The copper sliding contact line is erected together with the utility pole in the air, with the weight supported by the cross-arm, ensuring that the horizontal copper sliding contact line is fixed on the insulator clamp. Several copper tram wires are placed horizontally, with a spacing of about 300 mm. The end of the sliding line is equipped with a terminal suspension device, ensuring that the copper sliding contact line can be reliably maintained in a horizontal tension state, and ensuring reliable power supply for the gantry crane.
