In recent years, viaducts and high-rise buildings continue to emerge, and there are more and more high-altitude operations. The demand for high-altitude vehicles is also increasing. High-altitude vehicles belong to construction machinery vehicles, and the malfunctions of high-altitude vehicles are high-risk failures. What are the common breakdowns of cars and how can they be avoided and eliminated? The following Chinese car network Xiaobian brings you the common troubleshooting methods for aerial work vehicles. Common fault 1 : From the pressure gauge to see the pressure of the institutions is very low, can not get into the leg, the amplitude of the boom page can not get up, turntable does not move, There may be several reasons 1. The relief valve opening pressure is too low. 2. The oil level in the tank is too low or the suction pipe is clogged. 3. Excessive collusion or leakage of the pressure and return lines so that large amounts of oil flow back into the tank without taking part in the work 4. The pump has been damaged or leaked too much. Method of exclusion: 1. Adjust relief valve opening pressure 2. Add new oil or check suction tube 3. Check the oil circuit, especially various valve locks, motors, etc. 4. Inspect the oil pump for maintenance or new ones. Common Fault 2 : Oil Leak in Hydraulic System the reason: Loose joint 1 2 The seal is damaged 3 pipe edge cracking or welded joints oil sand eyes Method of exclusion: 1 tightening 2 new 3 repair or renew Common fault 3 : Throttle control valve is not working the reason: 1 The wire rope is stuck in the system 2 spring damage 3 trips due to loose ropes 4 lack of lubricant Remedy: 1 maintenance 2 new 3 adjustment stroke; fastening 4 Lubricate each P bit Common fault 4 Pressure gauge oil does not indicate or pressure does not rise the reason: 1 The oil level of the tank is too low or the suction pipe is blocked 2 relief valve adjustment pressure is too low 3 The edge of the pipe before the oil pump inlet is not sealed 4 oil pump damage or serious leakage due to wear inside 5 Pressure pipeline or return pipeline collusion or leakage is too large 6 pressure gauge is damaged Method of exclusion: 1 Refuel and remove foreign matter 2 Adjust pressure as required 3 Exclude from leaks 4 overhaul or renew 5 or repair or change 6 or repair or change Common fault 5 　　 Severe noise in the oil circuit the reason: 1 There is air in the pipeline 2 component failure 3 pipe edge components are not tight 4 reversal too fast 5 oil temperature is too low 6 oil shortage 7 pipeline blockage Method of exclusion: 1 The agencies repeatedly performed many actions to eliminate internal gas and to inspect the oil pump. 2 repair or change 3 fastening plus pipe card 4 Slow operation 5 no-load operation heating 6 oiling 7 clearing Common fault 6 　　 Oil temperature overheating the reason: 1 Internal leakage is too large 2 high pressure 3 long working hours and high ambient temperature (summer) Method of exclusion: 1 maintenance components 2 adjust the pressure 3 stop and rest and then work after cooling. The above is a common breakdown of high-altitude trucks and their causes and remedies. Occasionally, some small faults may lead to catastrophes. If we find that there are even a few small problems with the aerial vehicles, we should promptly resolve them.
