aprox 10 tonnes
a multiplier of 5
because when we r applying a certain load the deflection also increasing..))
Load halved means the power is halved.Voltage being (assumed) constant, the current is halved. P (Load in Watts)= V x I Hence P/2= V x I/2

To calculate the safe working load of a ship's bollard, you need the working stress and the force applied. These two will help you compute the safe working load.
the safe working load is the load the stand can support safely without failure. It Is called safe because it can generally stand up to five times the safe load but one should not intentionally exceed the safe load. Safe load is also called working load or rated load
The SWL stands for - Safe Working Load
SWL means Safe Working Load
The safe working load can be calculated using the 6 x 19 &. 6 x 36 classification.
The initials SWL mean Safe Working Load
Every six months
S.W.L on a vehicle workshop hoist stands for Safe Working Load
Working Load Limit used for replacing Safe Working LoadBoth of these two terminologies are used for industry as load limit terminology when evaluating the maximum force allowable during lifting or holding. Because of numerous environmental factors, manufacturers no longer find the term "Safe Working Load" accurately descriptive for maximum rated loads in equipment standards.Manufacturers all over the globe are concerned with effectively assigning load limits to avoid "plastic deformation" or stress effects during continued use of rigging equipment. These limits do not infer safety because so many factors can affect equipment with use in various environmental heat, cold and wet extremes over time.
To convert breaking strain to safe working load you must establish a safety factor (SF). Assume SF of 10. If a line has a breaking strain of 1 tonne then you should only suspend or load the line to a strain of 100Kg (1000Kg/10) A common SF for normal use is 6. If human loads are in use then SF 10 is more common.
subtract the tare weight from gross weight, this is your net weight, after you multiply the weight the chain can support and how many chain you are using if this result is biger or same than the net weight then this is go na be your safe working load .
There are several ways to calculate working load limit. One of these includes Minimum Breaking Load (MBL) divided by Working Load Limit (WLL) equals Working Load Limit (WLL).
