13mm Wire Rope Swl

General purpose wire ropes.

13mm wire rope swl.

The wire rope has an equal lay construction warrington seale and achieves a superior breaking load to the 6x19 construction range. Rope diameter minimum breaking strength safe load weight in mm lb f kn lb f kn lb m ft kg m 1 4. Forsling swl depends on the length of the sling leg l and the headroom between the hook and the load h. As we all known.

Example for 12 mm dia wire rope. 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. The result is the safe working load in tons. Diameter in mm squared the weight in kg.

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. Swl wire rope dia 2 8 kgs. All diameters are measured in millimetres mm. Likewise the 1960 grade tensile ensures high breaking loads but a very good balance of strength and fatigue resistance for the longest.

Click here for. For wire rope fs is 6 for general purpose and 7 for heavy industry. 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. Then for bridge hitch.

All weight are calculated in kilograms kg. The term safe working load swl has been the cornerstone of engineering particularly with regard to load carrying equipment for many years. The wire rope is 1 2 inch in diameter. Compute the swl for the rope.

Charles missouri 63303 866 852 9714. A thumb rule formula is. 2086 exchange drive st. The safe working load is the mass that lifting equipment usually a wire cable can safely hold without fear of breaking.

The 6x36 construction provides an excellent balance of flexibility and durability. 6x36 is a flexible general engineering wire rope readily available in galvanised ungalvanised and marine grade stainless steel. Swl 12 12 8 1152kgs. Nobles stock 6x36 iwrc galvanised 1960 grade wire ropes for all general purpose applications.

To help demonstrate the breaking limit of wire rope the engineering toolbox have put together this handy table. The first step is to convert the 1 2 into decimal number by dividing the bottom number of the fraction into the top number of the fraction. 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.
