Methods for troubleshooting construction elevator circuit faults.

When we carry out high-altitude operations, we often use construction elevators. However, encountering a short circuit in the circuit during use is a very headache, especially in the hot summer and when the working circuit is heated for a long time, it is easy to cause a short circuit in the circuit. This can easily cause the motor or electrical box of the construction elevator to burn out, causing it to be paralyzed and unusable. Therefore, it is crucial to do a good job of checking the circuit of the construction elevator. So, what are the methods to eliminate the fault of the construction elevator circuit?
1. Check for aging, exposure, or damage to the construction elevator circuit.
2. When using voltage range to detect construction elevators, it is necessary to connect the power supply, and then measure the voltage according to the circuit schematic. The fault point is determined and analyzed based on the measured voltage value.
3. After connecting the power supply, check whether the indicator light of the construction lifting mechanical and electrical box is working, and eliminate the short circuit between the power sources. At this time, a large short circuit current will be generated, burning the fuse melt. This situation is more obvious, so it can be detected and eliminated when analyzing the circuit.
4. When checking with a resistance level, it is necessary to disconnect the power supply and measure it through the circuit schematic. Based on the measured resistance value, the fault point can be analyzed.
5. Conduct no-load and load tests on the construction elevator to check if the relay can open and close freely. When the contacts are bonded, the switch will not release continuously. When this short circuit occurs, it will not generate a large current and the fuse will not be damaged.
6. When using a universal meter to check for faults in hydraulic construction elevators, resistance, and voltage levels can be used for detection.
When we use the short circuit method to check the circuit faults of the construction elevator, we can use the control schematic diagram of the construction elevator as a basis to short-circuit the possible faulty contacts, switches, etc. After short-circuiting, if the fault is eliminated, it indicates that the fault is in this part. After narrowing the scope, we can check again to know where the fault point is.
Construction elevators are intelligent lifting, loading and unloading, and handling mechanical equipment. The scissor-type mechanical system ensures high reliability of the lifting platform, and the construction lifting mechanism of the electric lifting platform is operated by a hydraulic press driver. The spacious work platform and high load-bearing capacity make the working range at heights higher, and more people are suitable for other jobs. This ensures safer mechanical equipment and higher efficiency in high-altitude operations.
Actual operation of construction elevators.
When using construction elevators, each person only needs to connect to the switch power supply, and the hydraulic press and home appliance system software does not need to be adjusted. Due to the testing and adjustment of the lifting platform before leaving the factory, all performance indicators meet the design requirements; Before using the construction elevator, check the hydraulic press, household appliance system software, and other positions., Ensure that there is no multi-directional leakage or exposure before use; When using the lifting platform, the four supporting feet should be firmly supported on a solid road surface (based on the road surface where the walking wheels are about to leave). Wooden pillows can be used if necessary; 4. The electric hydraulic lifting platform can perform multiple operations before being loaded; 5. The center of gravity of the platform payload should be located as much as possible in the management center of the platform; When using a manual pump, tighten the return valve knob clockwise, press the handle to maintain the neutral position, and press the handle to lift the platform.
