The main components of wire rope electric hoists include reducers, running mechanisms, drum devices, hook devices, couplings, flexible cable current feeders, limiters, etc. Wire rope electric hoists are one of the commonly used lifting devices in factories, mines, ports, warehouses, freight yards, stores, etc., and are essential machinery for improving labor efficiency and working conditions.
Electric wire rope hoists are often used in overhead cranes, jib cranes, and single-girder cranes. Due to their simple structure, convenient manufacturing and maintenance, good interchangeability, and easy operation, they are widely used in factories. If their safety devices are incomplete or are used improperly, it can cause casualties. Therefore, in addition to being trained and holding certificates as required, operators of electric hoists must strictly abide by the following operating regulations:
1. Before starting, carefully check whether the mechanical, electrical, wire rope, hook, and limiters of the equipment are in good condition and reliable.
2. Do not lift loads beyond the rated capacity. When lifting, hands must not be placed between the rope and the object. When the lifted object is rising, be careful not to hit the top.
3. When lifting objects, the safety operation regulations for hooking and lifting workers must be followed. The objects should be securely fastened, and protective pads should be placed at sharp corners and notches of the objects.
4. When using the drag line electrical switch to start, the insulation must be good. Press the button correctly and pay attention to the standing position during operation.
5. When the monorail electric hoist is approaching the end of the track or turning at the track bend, it must run at a reduced speed.
6. Wire Rope electric hoists with operating rooms must be operated by designated personnel and must strictly follow the relevant safety operation regulations for crane operators.
1. Overloading or the weight of the object is unknown, such as lifting buried objects with unclear weight or pulling force, and slanting lifting and pulling.
2. There are defects or damages in the structure or components that affect safe operation, such as failure of the brake or safety device, damage to the anti-loosening device of the hook nut, and damage to the steel wire rope reaching the scrapping standard.
3. The object is not securely bound or hung and may slide, and there is no padding between the sharp corners of the object and the steel wire rope.
4. There are people or floating objects on the lifted object.
5. The work site is dim, and the site, the lifted object, and the command signals cannot be seen clearly.
All in all, the wire rope electric hoist are very popular in the lifting machine market. Besides it, we also produce and export electric chain hoist, electric winch and pneumatic winch,etc, Any needs, please contact us at any time!
