Deformation inspection of the upper hook of the hand zipper chain hoist

There is not much difference between the upper and lower hooks of a 1-ton zipper chain hoist, except for the different hook shafts. Most hoists use A-type or X-type hooks. The high-quality hand zipper chain hoist hook in Kemei can be distinguished from ordinary ones in terms of workmanship, design details, and accessories. When we install and use it, the direction of force or weight may affect the performance of the hand chain hoist hook, and incorrect use can easily cause deformation or wear.

If there is slight deformation of the hook, it is generally difficult to detect it with the naked eye, and it is necessary to measure and observe whether the width inside the hook has changed. But some deformations may not necessarily be an increase in width, they can be changes in various angles, so we can detect wear by measuring distance, but not necessarily deformation. To solve this problem, there are three protruding points on one side of the hook of the Komei manual hoist, which can be used to determine whether it is deformed. Normally, it is in a straight line. At the same time, good hooks generally do not deform or wear, and the entire hook has been widened to a certain extent. The cast steel locking plate is embedded, which is more sturdy and safe than ordinary hooks, and the hook is not easy to fall off.

The upper and lower hooks, including some key components inside the gourd, have high strength, but common problems cannot be ignored. Correct operating procedures are the main method to avoid deformation or wear.
