Mast top rear leg pin for Favelle Favco

The mast top rear leg pin M305-0073-0300 serves as a structural connection point within the tower mast assembly of Favelle Favco cranes. It functions by securing the upper mast sections to the rear support legs, establishing the necessary pivot or fixed connection required for the stability of the crane structure. By maintaining the alignment of the tower sections, this pin facilitates the safe transfer of forces throughout the mast during lifting operations.

This component features a diameter of 85 mm and is engineered specifically for integration into the mast systems of Favelle Favco tower cranes. It is designed to maintain the verticality and structural integrity of the mast assembly under the operational loads typical of high-rise construction and large infrastructure projects. Regular inspection of the pin is necessary to ensure it remains free from deformation or fatigue, as it is a critical element in the overall load-bearing path of the crane tower.

In tower crane assemblies, pins of this type act as the primary mechanical fasteners that link structural steel members. They are subjected to significant shear forces and must be precisely sized to fit the corresponding mast leg lugs to prevent movement or play within the connection, which is vital for the operational safety of the crane.
