These security rings are specially designed for turning charges.
They are able to solve all hoisting situation, whether with a skew or axial lifting, and /or stowing.
- Their design allows use in allows direction and lateral fixing.
- These rings have to be screwed following the tightening torque specified by the manufacturer.
- Rings with low overhand would be preferable.

Preferably use rings whose axes are inseparable from the equipment, in order to avoid replacing the axis by an inadequate one.
Fixed lifting rings:
Traditional DIN 580 rings are meant for linear tractions in the direction of the fixing bolt. They are forbidden for tractions perpendicular to the direction of the fixing bolt.
Why?
- They can easily unscrew when handling and move in the direction of traction.
- They can possibly twist or break (increased risk if the ring was already bent in opposite direction, that’s why bended rings have to be removed.).
- Loss of at least 75% of their effectiveness as soon as the traction is no longer linear.
When using fixed rings, preference will be given to rings:
-
With the following engravings (to meet prevailing standards):
- Manufacturing batch
- Blacksmith reference
- Type of material
- Diameter
- Supplied with a certificate of conformity (specifying the material analysis)
