Specialize electric wire rope hoist is a mechanical device for lifting heavy objects vertically. Generally speaking, the electric hoist with a large rated lifting tonnage has a large body size, and vice versa. In addition to judging the rated lifting capacity of the electric hoist from the two aspects of the body shape and the nameplate information of the electric hoist, we can also judge from the hook parts of the electric hoist.
The hook of the specialize electric wire rope hoist is forged from carbon structural steel, suspended on the single-row thrust ball bearing in the beam, and connected with the pulley through the beam and the hook shell. Some hooks are marked with numbers such as 3t or 5t, which is enough to explain the carrying capacity of the hook. We can use this as a reference to judge the actual carrying capacity of the electric hoist.
At the same time, we can also judge the tonnage of the specialize electric wire rope hoist according to the appearance of the hook. Specifically, the hook device of an electric hoist with a tonnage of 5 tons or less is a single pulley type, while the hook device of an electric hoist with a tonnage of 10 tons or more is a double pulley type.
The tonnage of the specialize electric wire rope hoist is different, and the structure and size of each component are also different.
