Topic: Safety Operation Regulations of Electric Chain Hoist
Electric chain hoists are often used on monorail cranes, cantilever cranes and manual single beam cranes. Because of their simple structure, convenient manufacturing and maintenance, good interchangeability, and easy operation, they are widely used in engineering. If its safety devices are incomplete and improperly used, it will cause casualties. Therefore, the electric hoist operator must strictly abide by the following operating regulations in addition to training and operating with a certificate according to regulations:
01. Before starting, check carefully whether the equipment's mechanical, electrical, wire rope, hook, stopper, etc. are in good condition and reliable.
02. Do not lift overloaded, do not hold hands between the rope and the object when lifting, and prevent the top from hitting the top when the hanging object rises.
03. When lifting objects, you must comply with the safety operating rules of hook lifters. The strapping should be firm, and the sharp corner of the object should be protected by padding.
04. Use the electrical switch of the towing line to start, the insulation must be good, press the button correctly, and pay attention to the standing position during operation.
05. When the monorail electric hoist is turning on the track or approaching the end of the track, it must run at a reduced speed.
06. Any electric hoist with an operating room must be operated by a dedicated person, and it is strictly forbidden to follow the relevant safety operation regulations of the operator.
07. When the electric chain hoist is not working, it is forbidden to hang heavy objects in the air to prevent the parts from deforming.
08. The electric hoist should have enough lubricating oil and keep it clean.
09. Disc brakes should be adjusted with springs so that the objects can be easily suspended, and the brake hoist should not exceed 80mm under heavy load.
10. Before use, static load and dynamic load test should be carried out.
11. Check whether there is grease on the brake pads of the brake, and all contacts must not be lubricated or flattened with a file.
12. It is strictly prohibited to use it with overload, and it is not allowed to tilt or use it as a drag tool.
13. When operating, the operator should pay attention to and promptly eliminate the abnormal situation of the steel wire rope falling off the groove on the reel or winding two layers.
In addition to the above, there are many noteworthy details. As the so-called details determine success or failure, I hope everyone will pay more attention to the details and stop using them immediately if they find abnormalities. The use of electric hoists must establish a sense of crisis, strictly abide by operating regulations, pay attention to details, and pay attention to maintenance.
