　　Container spreader is a special spreader for container cranes. Due to the different sizes and weights of containers, their spreaders are different. They can be divided into integral (fixed type), replacement type, mother-child type, telescopic type, etc. The locking mechanism consists of a locking cylinder, connecting rod, crank, locking shaft head and other components. Insert the rotary lock shaft head into the elliptical hole at the corner of the box. After the driver receives the signal, rotate the rotary lock shaft head to lock the spreader and container.

　　Container spreaders are particularly prone to spreaders corrosion when used in marine or industrial pollution environments. Corrosion not only reduces the metal area of the wire rope, thereby reducing the fracture strength, but also causes roughness of the surface, which in turn leads to cracks, thereby accelerating fatigue. If the corrosion is serious, it will also cause the rope to be elastic.

　　1. External corrosion

　　The corrosion of the steel wire outside the crane can be observed with the naked eye. There are deep pits on the surface, and the steel wire should be scrapped when it is loose. 2. Internal corrosion

　　Internal corrosion is more difficult to detect than the external corrosion that is often accompanied by. But what can be confirmed is the following phenomenon:

　　1. Changes in the diameter of the wire rope. At the bends around the pulley, the diameter of the wire rope is usually reduced. However, for the stationary section of the wire rope, the diameter of the wire rope is often increased due to corrosion of the outer rope strand.

　　2. The gap between the outer rope strands of the wire rope is reduced, and the wire breakage between the outer rope strands is also often occur.

　　If there are corrosive marks inside, the wire rope should be inspected internally by the manager. If serious internal corrosion is found, the wire rope should be stopped immediately.

　　To sum up, if a serious corrosion is found in the assembly packing spreader can no longer be used! If you have any questions or needs, you can contact us directly, or leave your needs and contact information directly on the website, and we will contact you in time!
