Huai'an Crane Rental Company Take you to understand the common sense of small crane hook maintenance!

During the transfer of crane accessories, especially in the case of poor road surface at the operation site, the relative friction between the wire rope and the hook will be greater, resulting in wear of the hook and wire rope. Since both ends of the steel wire rope are hung on the traction hooks on both sides, the steel wire rope is like a lute rope, which severely abrades the vertical dangerous section of the hook. In poor road conditions, such as the crane The hooks are particularly worn during field operation, and some need to replace a steel wire rope within a few months to lock the hooks.

This kind of wear of the hook is non working wear. The method to reduce and prevent such abrasion is to take a steel wire rope with a length of about 4.2m and fix both ends with rope clamps. In this way, the contact between the wire rope and the hook is changed from one to three, which increases the contact area between the wire rope and the hook, reduces the friction and wear between the two, solves the problem that one wire rope is easy to scratch into the hook surface, extends the service life of the hook and rigging, and also extends the service life of the hook locking wire rope. Take a 400mm long steel pipe with a diameter of 25.4mm and place it on the steel wire rope.

On the crane Equipment displacement During the operation of, because the wire rope has no direct contact with the hook surface, the sleeve plays a role in protecting the hook. Other materials such as thick rubber hose, high pressure hose and steel wire mesh can also be used for casing.
