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.
• Painted in red, they remind security (product of at least class 8).

The engravings state:

• The EC reference if compliant to EC directives;
• The class;
• The manufacturer brand and the blacksmith’ mark, when forged;
• The batch n°;
• The diameter;
• The maximum CMU/WLL.

The delivery will be completed by:

• The recommendations for use;
• The certificate of conformity

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)
