Swl wire rope dia 2 8 kgs.
13mm wire rope swl.
As we all known.
Forsling swl depends on the length of the sling leg l and the headroom between the hook and the load h.
Nobles stock 6x36 iwrc galvanised 1960 grade wire ropes for all general purpose applications.
The 6x36 construction provides an excellent balance of flexibility and durability.
The wire rope has an equal lay construction warrington seale and achieves a superior breaking load to the 6x19 construction range.
Wire rope and chain are the important part of the hoist which are closely bound up with the safe work load now let s talk about how to calculate the swl of ropes and chains.
6x36 is a flexible general engineering wire rope readily available in galvanised ungalvanised and marine grade stainless steel.
The wire rope is 1 2 inch in diameter.

Diameter in mm squared the weight in kg.
The term safe working load swl has been the cornerstone of engineering particularly with regard to load carrying equipment for many years.
All diameters are measured in millimetres mm.
The safe working load is the mass that lifting equipment usually a wire cable can safely hold without fear of breaking.
It was generally considered to be the minimum breaking load of a component divided by an appropriate factor of safety giving a safe load that could be lifted or be carried.
Then for bridge hitch.

All weight are calculated in kilograms kg.
The formula for computing the swl of a wire rope is the diameter of the rope squared multiplied by 8 d x d x 8 swl in tons.
To help demonstrate the breaking limit of wire rope the engineering toolbox have put together this handy table.
They have also offered an example of the strength of 3 8 wire rope that has a safe working load of 10 9 kn.
The result is the safe working load in tons.
Likewise the 1960 grade tensile ensures high breaking loads but a very good balance of strength and fatigue resistance for the longest.
To calculate the swl you ll need to know the diameter of the rope in inches and apply it to the formula swl d x d x 8.
