July 2016 Project:

Evaluation of 360 Degree Sling Adapter
Evaluation of 360 Degree Sling Adapter

Our firm was tasked to design a 360 degree swivel adapter for use with an existing spreader beam that our firm designed many years ago. The required suspended load was significant: 180 tons. The adapter also had to be capable of swiveling 360 degrees and swinging up to 30 degrees to allow for unsymmetric loading.


Using both hand calculations prescribed by ASME BTH-1 and finite element analysis software, our engineering team designed a sling adapter that satisfied the strength requirements for the maximum load desired by the client, and was capable of both swiveling and swinging.
