Cranes typically are designed with a FoS (Factor of Safety) of 5x the MBL (Minimum Breaking Load). So if the weakest part of the structure failed (e.g. in tension, compression or shear) at e.g. 100kN (10 metric tons), then the swl would be 10t / 5 = 2 tons
it is 0.5mm per meter span of the crane girder

1.1~ 1.3 * Load of winches Depend on Angel of boom in Max load
You will need a footing to support a moment of 21,000 ft.lbs.Moment = Arm x ForceMoment = 1000 lbs. x 14 ft. = 21,000 ft.lbs.
Crane rocking clearance refers to how much space is available for a crane to move. A specific amount of space is needed to use a crane safely.
TO CALCULATE THE SWL OF LIFTING WIRE ROPE THE FORMULAE CAN BE USED- 8*D2 WHERE 'D' IS THE DIAMETER OF WIRE ROPE IN 'mm' THIS WILL GIVE THE APPROX SWL (SAFE WORKING LOAD CAPACITY)
If SLI is in operating condition then sLI itself will indicates that whether load is in safe mode. But if SLI is not working then one must be considered 40 % factor of safety of crane SWL and in SLI working condition it will be considered 20 % of its SWL.
The safe working load (SWL) for a 3000-ton crane can vary based on several factors, including the crane's design, configuration, and the conditions under which it is operated. Generally, cranes are rated with a safety factor that typically ranges from 5:1 to 10:1, depending on industry standards and regulations. Therefore, for a 3000-ton crane, the SWL would likely be lower than its maximum capacity, determined by the manufacturer’s specifications and safety guidelines. Always consult the crane's load chart and operational manuals for precise SWL information.
Yeah! (D X 8), where, D= Diameter!
The SWL stands for - Safe Working Load
SWL tons, or Safe Working Load tons, refers to the maximum load that a piece of equipment, such as a crane or lifting device, can safely handle without risk of failure. This measurement ensures that operators do not exceed the limits, promoting safety in lifting operations. It's crucial for preventing accidents and ensuring the longevity of the equipment. Always refer to the manufacturer's guidelines for specific SWL ratings.
SWL means Safe Working Load

how i will calculate eot crane long travel wheel
calculate radius of crane: The radius is always measured from the centre of rotation and is the radius measured after the boom deflects forward when under load.
