САЖЕТАК / ABSTRACT:

Shackle is a device used for lifting heavy loads by cranes. They can be closed type – forged shackles or articulated shackles. The weight of the shackle is the load that the crane always has to lift, which reduces the load capacity and increases the required lifting power. In order to reduce the required lifting power and increase the carrying capacity, it is necessary that the dimensions of the shackle have the minimum required value at the prescribed safety degree. This paper analyses the stress state of shackle analytically and numerically using the finite element method (FEM). At the end of the paper, a comparison of the obtained results is given.
