Wire rope hoists are a type of equipment required for small cranes. They can be installed separately on I-beams or on different types of cranes. It has the advantages of being light and easy to operate. This article introduces the main points and precautions for the safety inspection of wire rope hoists in daily use.
First, daily safety inspection points
1. Always check the anchor bolts to ensure that it does not loosen.
2. Check the box of the reducer. The key point is that the heating temperature at the bearing cannot exceed the standard value. If the temperature is 40 ° C, check the bearing for damage, lack of grease, and whether it is stuck.
3. Check the lubrication area. When the wire rope hoist is used in the initial stage, the frequency of changing the lubricating oil is once every quarter, and then it can be adjusted to half a year or once a year according to the actual situation. The amount of oil in the lubricating oil should be moderate and there should be no leakage.
4. The shaft and gear can be judged to be damaged by listening to the gear meshing sound. Under normal circumstances, the sound should be even and brisk. If there is high noise and abnormal impact, you need to check the box.
5. When checking the shaft of the gearbox, you can use magnetic or ultrasonic waves. If there is any problem, you should deal with it in time.
6. The outer casing of the electric hoist may not be deformed or cracked.
Second, the use of wire rope hoist precautions
1. When selecting the gourd, first determine the tonnage according to the actual load size, and then select the corresponding gourd.
2. Fix the hoist firmly with the wire rope of the specified model and specification.
3. In operation, the wire rope that meets the requirements must be used; in operation, the wire rope should be kept clean, and some impurities and oil can not be allowed to enter the machine, which will affect the normal use of the machine.
4. The machine does not need to be lubricated during the process of use.
5, can not use any lengthened handle, otherwise it will cause other handles to jam, affecting the normal use of the machine.
6. If there are special circumstances, the hoist should be used in other equipment lifting. The lifting weight of the hoist cannot be calculated according to the standard lifting weight, and should be reduced to one-third of the rated lifting weight.
