Wire rope sling WJT series

steel

In the form, grommet sling was spliced by the wire rope with the characters of class b or ab, fiber core, nominal tensile strength 1670MPa. Depending on the different working place, we should chose the rope with different surface treated, including galvanized wire rope with lubrication, galavnized wire rope without lubrication and un-galvanized, total three choices. Choose different capacity wire rope to splice the grommet sling, it's breaking load is different. Shall calculate the sling's breaking strength according to the steel wire rope construction. Min Breaking load of grommet sling is 5 times of that working load. Accroding to the requirements of the industry, other safety factors also can be applied. The safety factory of the following operation can be executed with the strandar GB/T30587-2014, such as the load weihght is accurate calculated or meassured, hoist operation is to be monitored and controlled and dynamic coefficient are limited. The same, when the diameter is 60 mm or less than, take the safety factor of 5, the diameter from 60 to 150 mm take the safety of (6.31-0.022D), when the diameter is greater than 150mm, safety factor should not be less than 3. Special for limited space lifting, the shortest sling circumference should be 50 times of sling diameter.
