The GRADUP range has been espacially developed by CODIPRO. GRADUP lifting rings offer improved WLL and have a special anti-corrosion coating.
From the unit to the large series, from the standard to the specific, CODIPRO manufactures and sells a complete range of swivel lifting rings for different sectors: the mold industry, handling, transport, logistics, the naval industry, offshore, lifting, aeronautics, wind energy, etc.
Fixed eye bolts are intended for straight lifting: at a maximum angle of 45° to the pulling direction. They are strictly prohibited for perpendicular lifting.
Why 45° maximum?
Swivel lifting rings are specially designed for turning loads. CODIPRO rings can be used in any kind of lifting situation whether there is an angle or for a straight lift, and/or for all types of anchoring.
The design of CODIPRO swivel rings allows pulling from any angle and to rotate safely under load. Painted in orange (RAL 2002), the color is a sign for safety. The laser engravings of the CODIPRO rings state:
CODIPRO offers swivel lifting rings with two safety factors: 4 and 5.
In Europe, it is customary to use the safety factor 4. It is this safety factor that is specified in the EN 1677-1 standard. For the sake of clarity and transparency, CODIPRO approved all its GRADUP rings to a 4 factor to allow the trained operator to use it under these conditions.
True to its values, CODIPRO has however always favored the factor 5 because it remains the best guarantee of quality and safety. Therefore, CODIPRO’s GRADUP rings are engraved with the WLL of the safety factor 5. In addition to enhanced safety, our lifting rings can thus be used on every continent with no restrictions.
The double swivel ring DSR has been especially designed to guarantee liftings under load. Its double articulation allows it to line up perfectly with the sling.More information

Why is it important to check the tightening torque when assembling CODIPRO lifting rings?
16/03/2022 : The tightening torque is the force that must be applied to a screw to assemble two pieces together. The pieces are hold together due to a principle of adhesion
