Differences Between WLL and SWL

Differences Between WLL and SWL

WLL and SWL are abbreviatons for Working Load Limit (WLL) and Safe Working Load (SWL). The main difference between the two terms is that SWL is the older term. Today, SWL isn't used anymore because the term is completely replaced with WLL and MRC.

What is MBL in lifting?

Other synonyms include Working Load Limit (WLL), which is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield, also known as the Minimum Breaking Load (MBL).

What is the difference between safe working load and breaking strength?

WLL refers to the maximum allowed weight that a particular piece of rigging can handle under normal conditions. ... WLL is 1/3 of the breaking strength rating, therefore a strap with a WLL of 6,000 pounds would have a breaking strength of 18,000 pounds.

What does WWL stand for in lifting?

WWL stands for Working Load Limit. The WLL is the maximum authorized load that can be borne when working with a device.

What is the meaning of SWL?

The Wikipedia definition of SWL is: Safe Working Load (SWL) sometimes stated as the Normal Working Load (NWL) is the mass or force that a piece of lifting equipment, lifting device or accessory can safely use to lift, suspend, or lower a mass without fear of breaking.

How is SWL calculated?

To calculate the SWL in kilograms of FSWR square the rope diameter (D) in millimetres (mm) and multiply by 8.

  1. Formula: SWL (kg) = D2(mm) x 8.
  2. Formula: D(mm) = √L(kg)

What is a 5 to 1 safety factor?

These slings are designed with a safety factor of 5:1. This means that 5 times as much force as the working load limit has to be applied to the sling before it potentially fails. This means the wire rope slings have a Breaking Strength of up to 180,000 lbs and the round synthetic slings can withhold up to 700,000 lbs.

How do you calculate load chart?

EXAMPLE: You need to lift a load of 15 tons (30,000 pounds) a distance of 25 feet. The distance is measured from the center pin of the crane to the center of the load. Once you determine the distance, look on that line for the largest capacity; that will indicate how many feet of boom must be extended.

What is safe working load of a rope?

There is a difference between the tensile strength of a rope and its safe working load. Tensile strength is the force required to break it, which can be determined by testing. ... This number is called the safe working load. The ratio between the working load and the rope's tensile strength is termed the safety margin.

What is a breaking load?

: stress or tension steadily applied and just sufficient to break or rupture.
