Summarize the sensory inspection of electric hoist for lifting
The safety technical inspection of electric hoist machinery is largely carried out by inspectors by looking, listening, smelling, asking and touching. Sensory inspection accounts for more than 70% of the total items in the related hoisting electric hoist machinery inspection items. Through the senses, see, listen, smell, ask and touch the comprehensive and intuitive diagnosis of the electric hoist machinery to obtain the required information and data.
Look: Observe the important transmission parts, key points of the load-bearing structure, and the source of the failure phenomenon according to the mechanical structure characteristics of the lifting electric hoist through vision.
Listening: Through auditory analysis, whether the operating sound of each part of the lifting electric hoist mechanical chain hoist equipment is normal, judge the abnormal sound from the position, understand the cause of the disease, and find out the source of the disease.
Smell: distinguish the on-site smell of the moving parts of the lifting electric hoist through the sense of smell, and identify the location of overheating, abrasion and overburning of parts.
Question: Ask the driver and related personnel about the easy failure points, the failure process, and the type of failure during the operation of the electric hoist. Determine the safety technical status of the electric hoist.
Touch: Touch the operating parts of the electric hoist by hand, and judge the location and nature of the fault according to temperature changes and vibration conditions.
