How to troubleshoot the electrical failure of a single beam crane?
When operating a single-beam crane, pay attention to ensuring the integrity of the lifting equipment. Irregular operation of the operator can easily lead to electrical failures. The editor of Henan Weihua Heavy Machinery Co., Ltd. introduces several single-beam crane electrical Troubleshooting methods.
1. Procedure inspection method: This method can quickly confirm which part of the equipment is faulty. When checking the electrical fault of the single beam crane, it is necessary to follow a certain procedure. Each link has an independent control circuit, but try to do the inspection as much as possible Reduce the scope of fault inspection and clarify the direction of troubleshooting.
2. Resistance measurement method: When the single-beam crane is out of power, the electrical lock of the universal meter can be used to measure whether the lock of the circuit element is normal. If the resistance value of the connecting element is zero or infinite, there is a possibility of failure.
3. Potential measurement method: This method is similar to the resistance measurement method. The actual position of the fault can be confirmed by measuring the two positions of each electronic component when the power is on.
4. Short circuit and open circuit measurement method: If you suspect that there is a short circuit or open circuit at a certain location, you can use the method of energizing after the wire short circuit or open circuit at some positions behind the contact to observe whether the fault disappears.
