Does a Crane's Safe Working Load Change with Different Lifting Conditions?

Please find attached the crane accident video for reference.

Question About Crane's Safe Working Load (SWL) Capacity

My question is: does the Safe Working Load (SWL) capacity of the crane decrease or remain the same when lifting any load, as shown in the video? Are there any factors, such as differences in levels, that could reduce the crane's capacity?

Kindly clarify my doubts.

Thank you.

Regards,

I am not talking about CG and other components. I am talking about level differences. In this video, the crane was positioned at a higher level, and we placed the material at a below-normal level.

Dear Amol,

Understanding Load Dynamics in Crane Operations

It is mere common sense to know about the increasing gravitational force as the load is being lowered, which needs to be taken into consideration in calculating the lift. Again, as the drop increases, there is a tendency for the load to dangle, causing a slight increase in the load weight. Wind load also increases in this condition.

If you watch closely, you can note that as the load is being lowered, the boom is extended, causing the crane to topple, which is the immediate cause of this accident. It does not matter whether the load is level with the crane or below the crane's level. You can be assured that as the load is being lowered, there is always an increase in load weight, which is negligible compared to other factors. This will never result in an accident, as other factors like the factor of safety are considered in a lift plan.
