How to calculate load Bearing capacity
How to calculate load Bearing capacity
(OP)
Hi,
I have a pump to be lifted which has no lugs to fit a hook. The pump weight is 1.4 tons. I have a hoist capacity 2 tons.
In order to lift the pump in absence of lug on the pump, pump flange is fitted with two Iron angles ( the pump size is rectangle so one angle each side is bolted to pump flange so that pump is lifted without any imbalance) bolted to the flange by two holes.
The angle is 4 inch X 4 inch and length is 2 feet and thkness is 0.5 inch.
Can any one tell if this is safe? could any one give a sample calculation please
Thanks

RE: How to calculate load Bearing capacity
As to whether the pump flange is adequate for lifting the pump like that, that would be a question for the manufacturer.
From your description, it sounds like you'd have some prying action going on at the flange face, and using a flat plate or something instead of angles would help if that were an issue.

I would start there rather than gerry-rigging something with the strong possibility of damaging the mounting holes of the flange brackets. Just a thought.
