Lifting sling.

Since 1955 the first synthetic fiber sling in the United States successfully applied to lifting the industrial field, it is widely used in ships, metallurgy, machinery, mining, petroleum, chemical, electrical, electronic, port, transport, military and other fields. Especially synthetic fiber lifting belt of portability, convenient maintenance and good chemical resistance, and has the advantages of light weight, high strength, are not easy to damage the lifting surfaces and other outstanding features, Ken Kam Limited it is more and more affected by the use of personnel of all ages and in many ways to gradually replace the steel wire rope rigging.

Lifting sling classification

Synthetic fiber sling by type, mainly divided into flat tape and round sling categories.

Flat tape is mainly composed of nylon fiber ( polyamide fiber ), polyester fiber ( polyester synthetic fiber ) and polypropylene (PP synthetic fiber). They have different characteristics, and can be suitable for different occasions, but different material tape absolutely can not mix.

Round sling material mainly polyester synthetic fiber ( polyester ), the outer layer of polyester tubes as a protective layer, and the inner core with a continuous 100% polyester core yarn as under hoisting load.

Lifting sling inspection

1 to detect each type, each kind of structure or material changes the first pieces of tape in the working load limit, and breaking test, test data obtained should reach 6 times the safety coefficient ( the customer special requirement except).

2 pairs of straps visually or manual checks, including measurement of main dimensions.

Sharp edge

When lifting objects with sharp edge, sharp edge to harness the devastating cuts, for the protection of tape from the cut, a protective lining on tape and was hanging between.

Ultraviolet rays

Exposure to continuous UV rays can damage synthetic sling intensity;

1, recommend these methods to avoid or arc welding by ultraviolet light effects:

When not in use,chitin lose weight the tape storage in ventilation, cool and dry place;

According to the tape using weekly to harness check once or repeatedly.

2, to UV damage degree of visual method:

Sling sling materials color fading; hardening; in the sling often contact load parts of the surface wear.

3, test

With the manufacturer, to continuous exposure to ultraviolet light harness test test.
