- Major accidents of mobile cranes are mostly due to
- 1. Before the operation, the tank level window should be used to determine if the hydraulic oil has been fully filled in accordance with the regulations. When refueling, be sure to go through
- One is sensory inspection; the other is using test instruments and meters to measure and control the equipment.
1 Sensory inspection A large part of the safety technical inspection of lifting machinery is performed by inspectors by looking, listening, sniffing, asking, and touching. "Hoisting machinery inspection regulations" (2002) No. 296 of the lifting machinery inspection projects accounted for more than 70% of the total project is sensory inspection. Obtain the required information and data through a comprehensive visual diagnosis of the lifting machinery through sensory seeing, hearing, smelling, asking, and touching.
Look: Observe the important transmission parts, the main points of the load-bearing structure, and the sources of failure phenomena by visually according to the structural characteristics of the lifting machine.
Hearing: Analyze whether the operating sound of various parts of the lifting equipment is normal through hearing, judge the abnormal sound from the part, understand the cause, and find out the source.
Smell: Distinguish the odor of the moving parts of the crane machinery by smell, and identify the location of overheating, wear and overheating of the parts.
Question: Ask the driver and related personnel during the crane operation process, which is prone to failure points, failure process and category. Determine the safety technical status of the crane.
Touch: By touching the running parts of the crane by hand, judge the location and nature of the fault according to temperature changes and vibrations.
2 Inspection of testing instruments According to the development trends of domestic and foreign lifting machinery, modern application of state monitoring and fault diagnosis technology has been widely promoted in the design and use of lifting machinery. In the operating state of the lifting machinery, use monitoring diagnostic instruments and expert monitoring systems to carry out inspection (supervision) of the lifting machinery, grasp the technical status of the crane at any time, predict the symptoms and reasons of the failure of the whole machine or system, and eliminate the accident from the bud status.
