In addition to being used as auxiliary lifting equipment, wire ropes can also be combined with hooks, connecting rings and other parts to form wire slings, and the combination form is very flexible. There are single-limb rigging and multi-limb rigging, and can be combined into limbs according to the lifting point. Rigging. When in use, only the connecting ring needs to be hung on the lifting tool, and some heavy objects that are inconvenient for a single chain can be hoisted. Its combination is to use its own soft characteristics, passing through the hook or connecting ring and then fixing the joint. Although the fixing place is very strong, it is also the most vulnerable place.
The steel wire rope acts as a link between the upper and lower parts, connecting heavy objects and lifting equipment, and will be in a tensioned state when loaded, which is very prone to fatigue damage, and as long as it is a metal rope, it has a certain degree of ductility. The rope is used for a long time. Cracks will appear on the surface and inside. Coupled with the extrusion deformation of the joint and the wear during use, it is extremely easy to break after the crack propagates.
The joint of the wire rope is the most vulnerable place, but as long as it is well maintained and checked regularly, the service life can be prolonged, and the replacement of the wire rope is very simple. If there is a problem, it can be replaced in time.
