Essential aerial working platform diagnosis parameters

Aerial working platform is an advanced special aerial asistant equipment. In the course of working, personal safety of the aerial working platform operator has a direct relationship with the work status and stability of aerial working platform. So timely discharge and predict of failure of the aerial working platform is very important. Aerial working platform is a mechanical, electrical and hydraulic integrated system which the structure is complex. Besides, Aerial working platform diagnosis could not only be structural, but also parametric, so it is difficult to locate and eliminate faults by manual fault diagnosis methods. Therefore, the hydraulic system of self-propelled and folding-arm type aerial working platform’s working is taken as a case, to develop a condition monitoring and aerial working platform diagnosis system to monitor its state timely and diagnosing its possible faults.

1. It summarizes the history, the current situation and the mechanical equipments and determined the research by combining the characteristics of the hydraulic system of aerial working platform’s working devices;
2. In depth analysis the structural characteristics and operation principles of the aerial working platform and its working devices’ hydraulic systems, and obtains the common faults of the hydraulic system of the aerial working devices and the mechanism, laying the foundation for its fault diagnosis;
3. It determines the parameters needed to be monitored by analyzing the actual running status and working condition of the hydraulic system of the aerial working platforms’ working device and the hardware design.
