The simple circuit problems of the mobile freight elevator can be simple faults such as poor line contact and loose joints. The following Passenger Elevator Factory lists some of the circuit problems and solutions for mobile freight elevators:
1. When using the voltage file to detect the mobile freight elevator, it is necessary to connect the power supply, and then measure the voltage according to the circuit schematic diagram, and determine and analyze the fault point through the measured voltage value. When using the resistance file to check, you need to disconnect the power supply, and then measure through the circuit schematic diagram, and analyze the fault point according to the measured resistance value. On-site maintenance personnel should be available when inspecting the circuit to prevent unauthorized opening and closing of the switch when inspecting the circuit, which may cause a safety accident.
2. When using a universal meter to check the failure of the mobile elevator freight elevator, the resistance and voltage files can be used for detection. When checking with the short-circuit method, you can use the control principle diagram of the mobile lift freight elevator as the basis to short-circuit the possible faulty contacts, switches, etc. After the short-circuit, if the fault is eliminated, the fault is in this part. After narrowing the scope, check again to know where the fault is.
