How much weight can a wire rope hold?
The working load limit (WLL) on common 5/16 steel cable is only 2000 pounds. The minimum breaking strength is approximately 10K pounds. So in many cases a 10K winch can be supplied with a steel cable with a minimum breaking strength of 10K.
How do you calculate wire rope load capacity?
To calculate the SWL in kilograms of FSWR square the rope diameter (D) in millimetres (mm) and multiply by 8.
- Formula: SWL (kg) = D2(mm) x 8.
- Formula: D(mm) = √L(kg)
What does 6×19 wire rope mean?

What is the working load limit of rope?
WLL refers to the maximum allowed weight that a piece of rigging can handle under normal conditions. For instance, a winch strap with a WLL of 6,000 pounds should not be used to secure any load above that weight, as it exceeds what it is rated for.
How much weight can a 3/8 cable hold?

What does 6×19 IWRC mean?
To most wire rope users, 6×19 means 9×25 filler wire. It is a common rope in the 6×19 classification. A standard 6x26WS design provides the best rope for a wide range of applications. In general, we recommend the use of 6x26WS in any application where a 6x25FW is used.
Which is stronger, wire rope or chain?
Lower initial cost and lighter in weight than alloy chain slings
What are the types of wire rope?
– Regular Lay – The wires line up with the axis of the rope. – Lang Lay – The wires form an angle with the axis of the rope. The wire lay and strand lay around the core in the same direction. – Alternate Lay – The wire rope consists of alternating regular lay and lang lay strands—used mainly for special applications.
Is there a difference between wire rope and stranded wire?
Wire ropes are usually ⅜” in diameter or larger, while cables or cords are smaller. Though this little distinction exists in aircraft and marine cables, wire ropes and cables are synonymous in most other ways. A strand is made up of two or more wires twisted around a center wire. Each strand is made up of 7, 19, or 37 wires.
