![]() ![]() If welding directly onto horizontal plate then the plate must be specified as EMZ grade to prevent delamination of the plate under tensile load. It is good practure to extend the base of the padeye to pass it completely through the structural member which it is connected to. Welding All padeyes must be welded to the primary struture by use of full penetration welds. The thickness of the padeye at the hole shall not be less than 75% of the inside width of the joining shackle The correct design of padeye should be selected based on the particular load application. The diameter of the holes in the padeye shall match the shackle used, clearance between shackle pin and padeye hole shall not exceed 6% of the shackle pin diameter. > 10%) out of plane loading, it is recommended that the shackle pin diameter is not less than 94% of the padeye hole diameter. For strength purposes the difference in hole and pin diameter should be as small as possible, but shackle pin maximum diameter including tolerance should be considered in order to ensure that the pin will enter the hole. The padeye hole diameter should be carefully selected to fit the shackle pin diameter. The pad eye thickness at the hole shall not be less than 75% the inside width of a shackle suitable for the RSF of the padeye. These must be fitted as additional plates welded onto the padeye profile and not a single boss The outside radius of the padeye main plate shall be no less than the diameter of the pin hole.įor padeyes rated above 2000kg capacity cheek plates must be fitted to reduce the play in the shackle-padeye connection. The ring stiffeners are attached to the main plate to take on the radial and lateral forces and prevent excessive deformation of the CHS. The main plate is conducted with a pair of cheek plates to stiffen the pinned connection and to prevent the main plate from failing due to bearing stress. For a multi-point lift it is essential that the padeyes point directly to the lift point centre to prevent lateral bending moments on the padeyes,Ī pad eye consists of a main plate and occasional ring stiffeners. ![]() If required plated supports can be added to the symmetric design to increase the lateral stiffness of the padeye, useful when the padeye will be subjected to dynamic load angles. The geometry of the padeye must match the size of shackle to be used to ensure a rated connection between the equipment and the lifting set.įor straight lifting angles a symmetric padeye design should be used, for a multi-point lift as in a offshore container or frame then a nonsymmetric design can be used. ISO-containers are not suited for use offshore (for instance the top beam is only a thin L-beam.padeye-construction gives lack in continuity between toprail and corner post.Padeye attached later on an ISO-container: Padeyes are welded with fillet welds on the ouside of the frame n Padeye plate is not in the correct angle n 2 shackles are joined together Bad design: Padeyes Too large hole in padeye
