The operation method for wiring of a single beam crane usually refers to a single beam bridge crane. The main beam of the bridge is mostly made of I-shaped steel or a combination of steel and steel plates. Generally, the electric hoist handle wiring of a single beam crane has a total of 9 wires. What is the wiring method for these 9 wires? Next, Shandong single beam crane manufacturer will briefly explain.
Firstly, it is necessary to clarify the purpose of these 9 wires. Among them, 6 are control wires in six directions: up, down, east, south, west, and north, and the other three are power wires, startup wires, and self-locking wires. The principle of wiring is generally to connect the power line to the emergency stop input line, the output line to the stop line, and the stop output line to the start input line.
Next, a crane needs to be installed and a wire rope needs to be installed. After the power cord is fixed, the three wires are connected to the three screws on the left side of the wiring terminal in the row. After being connected, the machine needs to be tested. If the wiring direction is opposite, any two wires need to be adjusted before the machine is tested.
When connecting the wiring in the cab and control box, plastic insulated wires need to be selected for the control circuit wiring. A certain amount of spare wires should be added according to the required quantity and length, and then they should be threaded into the wire duct together. According to the circuit diagram and wiring diagram, the wires after threading should be calibrated, numbered, and wired. Insulated plastic pipes should be installed at the inlet and outlet of the wire duct for protection.
