1250T double lifting hook

For the same 50 tons, the crane hook is much bigger than the crane hook.

One. Look at hook body strength calculation method (part comes from the textbook hoisting machinery design class, I think the textbook is the problem that most clearly) hook body strength calculation, the strength of the hook hook body if calculation using the methods of eccentric straight beam bending, the error is bigger, the multi-purpose curved beam bending theory calculation (as to whether the micronization straight beam can be in what specific cases relatively accurate account of curved beam, and the curved beam theory is really fantastic to be outside the scope of ability).

This calculation method is based on the principle that the maximum stress does not exceed the yield limit of the material (which is related to the calculation method, and the criterion).

It is different from general mechanical parts such as shafts and gears. Once the maximum stress exceeds the yield limit, permanent deformation will occur.

(the main difference in load bearing structure on the bearing stress and rigidity calculation theory judgment limits) for lifting hook, geometry size slightly change and no impact (rigid influence degree is not high), consider the ultimate bearing capacity of plastic deformation method is more reasonable.
