The TSR series is a lifting ring manufactured by Codipro. It enables the hook parallel movement from the supporting face of the ring at 90°.
The ring features a triple connection for lining up with the sling. There are two methods of tightening, which can be through an open-ended spanner, or with an Allen key. The models have a standard load capacity of 0.3 to 22 t, and 650 to 50 000 lbs.
TSR has class steel more than 8, and a 4 or 5 safety factor in compliance with the proposed WLL.
