Mobile hydraulic lift some failures are inevitable in the use of time, but the most important is the emergence of mobile hydraulic lifts how virtual power should be solved? What matters in the end the investigation which exist? In the investigation of the hydraulic lift electrical system failure process, often encountered in the line appears to be turning back to the platform, but the situation is not working properly, for less experienced maintenance personnel, the investigation of this failure very difficult. In fact, this situation is because most virtual electrical power generated by the system interferes with the judgment of failure. The so-called virtual power that is idling and the phenomenon of loss of pressure occurs after loading the measurement voltage is normal. Based on our experience in the maintenance virtual power generation it is mostly caused by poor contact line. Mobile hydraulic lift will be more popular, become the exclusive vehicle.
