Yes, it is possible to add an engraving on CODIPRO lifting rings. However, this engraving must not create confusion with the CODIPRO regulatory markings.

CODIPRO uses laser or micro-percussion to engrave its rings. The depth of the engraving can weaken the ring. It is therefore necessary to be careful.

Personalized engraving is possible on our rings in addition to our individual engraving. However, it is necessary to check the available space according to the number of characters and the ring model.

No, adding a washer between the base and the load to be lifted is not allowed. The thickness of the washer increases the lever arm of the ring (at 90°). It is recommended to use a ring with a shorter axis or with a spacer approved and mounted on the ring by CODIPRO.

The standard nuts delivered by CODIPRO are certified 2H nuts.

The rings can be delivered with nut and washer. However, it is necessary to make a request. The screws and bolts supplied by CODIPRO are galvanized and certified.

Yes. However, these conditions must be met:

• The markings must always be visible
• The paint must not interfere with the proper rotation of the ring or its tipping
• The ring must not be dismantled
• The ring must not be thermally stripped (e. g. hydrogen release) before painting

Some paints are patented. CODIPRO is not responsible for the use of this type of paint.

Yes, CODIPRO offers different types of surface treatment (white zinc plating, nickel plating, black oxidation, phosphating, …). Please contact CODIPRO for more information.

No, the standard nuts offered and sold by CODIPRO are not self-locking nuts. A self-locking nut has a height of less than 1x D and is not compatible with a standard CODIPRO ring.

YES, under the following link, you can consult some examples of specific rings that have been realized LINK. CODIPRO has the possibility to design swivel lifting rings adapted to your products or to your specifications. These rings are then tested in an approved and certified laboratory.

YES. CODIPRO can manage specific projects from A to Z thanks to its engineering department: the 3D modeling of a ring based on the customer’s product drawings, the global management of the specifications and the elaboration of customized solutions.

Yes. CODIPRO offers its EXPERTS, but also users, different trainings according to their needs. The training programs, given by experienced staff in lifting techniques, are available in 6 languages.

For further information, please contact Sébastien DEBLIRE (Training Manager).

All the components of the standard CODIPRO rings have a surface treatment more or less resistant to corrosion.

A centering is a “shoulder” machined on the flange of the base, allowing to reinforce the threaded axle during a shearing stress. The centering must imperatively be placed in a “counterbore” machined to the tolerances recommended in the part to be handled to validate its use.

In addition to the standard thread types (ISO METRIC and UNC “American”) CODIPRO manufactures rings with all types of threads (BSW, GAZ, Round, Trapezoidal…). Conical threads, not allowed for lifting, are not offered.

Yes, our rings have been approved to meet the lashing standards. The standard lifting rings will be engraved with a double inscription showing the WLL and the LC (Lashing Capacity) in daN.

The spacer is an intermediate element between the part to be handled and the lifting ring. It allows the ring to be offset from the load in order to avoid contact with a disturbing element around the thread. Discover the spacer in video by clicking here.

The double centering system allows to fix the lifting ring through a smooth hole (bore) in order to avoid a significant “shaft-bore” play. This also prevents damage to the thread and sometimes avoids oversizing the ring.

Yes. On request, it is possible to offer longer axles than the standard lengths.

Yes. Upon request and specifying the color code, it is possible to offer a different color shackle.

No, but they can be on request.
