SWL or WLL are calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.

## How do you calculate SWL?

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)

## How is crane capacity calculated?

Measuring the dimensions of this triangle will allow you to achieve an accurate crane load calculation.

- The standard calculation for maximum crane capacity is (r)(hC)/100.
- R = Radius between the ground and load.
- hC = Lifting height multiplied by the capacity.

## How much can a 50 ton crane lift?

Crawler Crane Information

It has a 50 ton (45.4 t) max lift capacity, 160 ft.

## How is SWL of D shackle calculated?

The formula used to find the Safe Working Load (SWL) of shackles is Diameter of shackle2 x 3. As determined by the vector diagram, the SWL in this example is 5.1 tons. Dividing 5.1 by 3 gives 1.7. … The proper size shackle will be the one just larger than 1.3″, in this case, the 1-3/8″ shackle.

## What is full form SWL?

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.

## Is WLL and SWL the same?

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’s the difference between SWL and WLL?

“WLL” stands for “working load limit” while “SWL” stands for “safe working load.” The main differences between safe working load from working load limit is that “SWL” is the older term. Today, SWL is not used anymore because it has been completely replaced by the term WLL.

## How much can a 40 ton crane lift?

Mobile Lifting Power & Distance

Hydraulic truck cranes vary in lifting power. It’s easy to tell how much a particular hydraulic truck crane can lift just by the name of it: A 40-ton crane can lift 40 tons (80,000 lb or 36,287 kg).

## How far can a 30 ton crane reach?

Hydraulic Truck Cranes

Hydraulic trucks range from 30 to 600 ton capacity and feature a hydraulic boom that can reach lengths up to 200 feet.

## What is the maximum weight a crane can lift?

So there is no one simple answer to the question, “how much weight can a crane lift?” On average, most cranes can lift loads between 10 and 60 tonnes. But some models can handle much more weight. Keep in mind that the capacity depends on the specific vehicle and the nature of the lift.

## How far can a 60 ton crane reach?

Truck Crane Information

Max Cap | 60 US Tons |
---|---|

Boom | 35-110 ft |

## What is the strongest crane in the world?

The Liebherr LTM 11200-9.1, built by the German company Liebherr Group, is the most powerful mobile crane ever built. It also has the longest telescopic boom in the world, which extends fully to 100 meters. It’s set on a double cab truck and can lift 1200 metric tons – that’s nearly 700 automobiles.

## How far can a 90 ton crane reach?

The Grove RT890 rough terrain crane has a capacity of 90 tons and a 5‑section full-power boom with a maximum length of 142 feet. With a MEGAFORM synchronized telescoping boom and an electronically controlled 275 Cummins diesel engine, the RT890 has the power and reach to conquer the most demanding jobs.
