Master link assembly is made of alloy steel by forging (welding) and treated with a special heat treatment process. It has the characteristics of small volume, light weight, and high strength. Usage and operation: The ultimate working load and scope of application of the primary and secondary rings are the basis for testing and use of the lifting ring, and overloading is strictly prohibited.

A combined lifting ring consisting of two or more sub rings of a main ring. The main ring is fully forged, and the sub ring is welded. The material is 20 chromium manganese titanium, with a specification of 1-100 tons and a safety factor of 4-5 times.

Master link assembly mainly used as a connection tool in lifting operations. Mainly used for assembling slings, sub-rings connected with double buckles and chain connections, assembled into synthetic rigging, used for lifting heavy objects and equipment, etc. It can be used in machinery, metallurgy, electricity, railway, water conservancy, ports, docks, papermaking Chemical industry.

Operating Guide for G80 hook series

G80 product plays a very important role in rigging and lifting industry which including eye hooks, clevis hooks, self-locking hooks, swivel hooks, sling hooks, eye slip hook with safety latch slip hooks, and so on.

For cranes, the hook is a very important device, and it is directly related to the lifting. Let's take a look at how to use the G80 hook correctly:

(1) G80 hooks cannot be cast, and trapped castings are prone to quality defects and cannot guarantee the mechanical properties of the materials;

(2) The general G80 hook is forged from a single piece of steel. The surface should be smooth. There must be no defects such as cracks, nicks, cracks, and sharp corners. Not allowed to wear or crack.

The hook is repaired and repaired. The hooks after repair welding will become brittle. The accident caused the fracture after breaking;

(3) Weld hooks and steel hooks cannot be used. Because the G80 hook is subjected to a large impact load when the brake is applied. Therefore, the strength cannot be used too high. Made of materials with low impact toughness.

(4) Use the rope buckle hook to hang the rope buckle to the bottom of the hook. Use the G80 hook to hook the loop of the component. G80 hooks can't be hard or twisted. In order to prevent the hook from being deformed or straightened, the member is detached.
