| Cable Diameter | Breaking Strength | Working Load Limit (5:1) Design Factor |
|---|---|---|
| 1/8″ | 2,000 lbs | 400 lbs |
| 3/16″ | 4,200 lbs | 840 lbs |
| 1/4″ | 7,000 lbs | 1,400 lbs |

How do you calculate wire rope capacity?
Formula: SWL (kg) = D2 (mm) For example: Diameter = 25 mm SWL (kg) = D2 (mm) SWL (kg) = D (mm) x D (mm) = 25 x 25 = 625 kg SWL (t) = 0.625 tonnes. The above equation can be reversed to calculate the diameter (D) in millimetres of fibre rope needed to lift a given load.
What is the breaking strength of 1/4 wire rope?
7000
7 x 19 Strand Cable
| 7×19 Strand | Size (in.) | Breaking Strength Galvanized Steel |
|---|---|---|
| 7/32″ | 5600 | |
| 1/4″ | 7000 | |
| 5/16″ | 9800 | |
| 3/8″ | 14400 |
How do you calculate work load of rope?
Once you know the diameter of the rope, you can apply it to the formula, which is SWL = D2 x 8. D represents the diameter of the rope in inches. If you’re working with a 1.5-inch diameter cable, for example, then the formula would be SWL = 1.52 x 8 or SWL = 2.25 x 8.
What is the strength of wire rope?
6×36 IWRC galvanised wire rope Tensile grade 1770N/MM2 Also offered in 1960 grade
| Size Diameter (mm ) | Appoximate Mass (Weight 100/Kgs) | Approximate SWL (FOS 5:1) |
|---|---|---|
| 9mm | 32.2 | 1.04 |
| 10mm | 39.8 | 1.28 |
| 11mm | 48.2 | 1.55 |
| 12mm | 57.3 | 1.85 |
What is breaking strength of rope?
The tensile strength is the load at which a new rope, tested under laboratory conditions, can be expected to break. Rope strength is the approximate average for new rope tested under ASTM test method D-6268. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 20%.
What is the tensile strength of a 1/4 inch steel cable?
Put me on the waiting list
| Cable Diameter | Breaking Strength | Working Load Limit (5:1) Design Factor |
|---|---|---|
| 1/8″ | 1,760 lbs | 352 lbs |
| 3/16″ | 3,700 lbs | 740 lbs |
| 1/4″ | 6,400 lbs | 1,280 lbs |
| 5/16″ | 9,000 lbs | 1,800 lbs |
What is the safe working load of wire rope?
Safe Working Load The way to determine the SWL is by squaring the diameter of the rope and multiplying it by 8 kgs. Thankfully, most wire rope distributors will present this calculation for you. The safe working load will change depending on the diameter of the wire rope and its weight per foot.
What is working load limit for rope?
Working load limit is always a fraction of tensile strength, allowing for a generous margin of safety. For wire ropes, it’s common for the working load limit to be set at 20% of tensile strength. However, you generally don’t have to be concerned about doing the math on your own.
How much weight can a rope hold?
New, unused Edelrid ropes of 10.5mm can be expected to support a weight of up to 28.4—28.9kN. Edelrid ropes that have undergone light glazing can typically withstand a force of 28-30kN. Finally, Edelrid ropes with nominal damage can withstand a force of up to 27kN.
How much weight can a cable wire hold?
Breaking strength is 4200 lbs and working load limit is 840 lbs. Cable weighs 0.065 pounds per foot and adheres to federal specification….Put me on the waiting list.
| Cable Diameter | Breaking Strength | Working Load Limit (5:1) Design Factor |
|---|---|---|
| 1/8″ | 2,000 lbs | 400 lbs |
| 3/16″ | 4,200 lbs | 840 lbs |
| 1/4″ | 7,000 lbs | 1,400 lbs |
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.
What does working load limit mean for rope?
Working load limit is defined as “the maximum load which should ever be applied to the product, even when the product is new and when the load is uniformly applied”. Working load limit is always a fraction of tensile strength, allowing for a generous margin of safety.
What is the formula for load?
Load weight = weight per volume * total volume.
What is the tensile strength of 1/4 steel cable?
Breaking strength: 6,400 lb. Weighs approximately 0.111 lb/per foot.
