MATERIAL

 

In accordance with standards DIN 580:2010 and DIN 582:2010, the carbon steel used for the construction of lifting eye bolts and lifting eye nuts is aluminium killed steel C15E (EN 10084/98).

A2 (AISI 304) or A4 (AISI 316)  stainless steel is also used for the construction of lifting eye bolts and lifting eye nuts.  Other materials can be employed for special applications. 

 

SURFACE FINISHES

 

Non-machined lifting eye bolts and lifting eye nuts are usually supplied as semi-finished forged pieces (sand-blasted).

White zinc-plated lifting eye bolts and lifting eye nuts (minimum 8 microns) and hot-dip galvanised lifting eye bolts and lifting eye nuts (minimum 78 microns) are also ready for immediate delivery. 
Other surface treatments are available on request (yellow zinc-plating, dacromet, Delta Protekt, Delta Tone, Delta Seal, painting etc.).

 

EU DIRECTIVES ON LIFTING EYE BOLTS AND LIFTING EYE NUTS SAFETY

 

EU Directive EN 2006/42/CE defines lifting eye bolts and lifting eye nuts as lifting accessories.  This means that the manufacturer/importer must respect all requirements outlined by EU Directives relative to marketing lifting eye bolts and lifting eye nuts in the EU.  Compliance with all EU norms and specifications is guaranteed by the CE marking of the lifting eye bolts and lifting eye nuts. 

Note: Pursuant to the laws and regulations on safety on the workplace, the user is also obliged to ensure that lifting eye bolts and lifting eye nuts, given that they are considered lifting accessories, possess all the characteristics required for the purpose of CE marking and that they comply with the reference Tables before they are put into use. 

 

The EU Directive and the reference tables outline the mandatory requirements for the sale and use of lifting eye bolts and lifting eye nuts within the EU, specifically:

 

• Lifting eye bolts and lifting eye nuts must be supplied with certificate 3.1 EN 10204.

• Lifting eye bolts and lifting eye nuts must bear the CE marking in the prescribed format. 

• Lifting eye bolts and lifting eye nuts must be marked indelibly with the manufacturer’s brand. 

• The lot number must be marked indelibly on the part (Traceability in case of product fault).

• The straight lifting Working Load Limit (WLL) must be marked indelibly on the part, together with an arrow indicating the lifting direction relative to the specified working limit. 

• The steel grade employed by the manufacturer must be marked indelibly on the part.

• The threading size must be marked indelibly on the part. 

• Packaging must include instructions for use. 

 

furthermore

• The manufacturer/importer must carry out 2 tests on different lifting eye bolts and lifting eye nuts for each manufactured lot: 2 straight pull tests and 2 orthogonal pull tests.  The result of these tests must not be lower than 6 times the working load limit (WLL) marked on the lifting eye bolts and lifting eye nuts. 

• The manufacturer/importer must carry out the chemical analysis and the mechanical tests (or possess the relevant certification) on the type of steel used for each lot.  The chemical composition and the mechanical values of these tests must be in accordance with the provisions outlined by the reference standard. 

• The manufacturer/importer must be able to trace at all times all the buyers of a lot of lifting eye bolts and lifting eye nuts in the event that an anomaly in the material and/or in the mechanical processing is found.   To this end, the manufacturer/importer must state the lot number for each type of eye bolt and eye nut   sold on the delivery note or on the sales invoice.  

• The manufacturer/importer must issue certificate 3.1 EN 10204 (2.2 EN 10204 for previous version of the tables) for each lot.  Users who are not in possession of the certificate must request it from the dealer before using the lifting eye bolts and lifting eye nuts, or from the manufacturer/importer if the dealer is no longer traceable.  Said certificate must be provided free of charge, as it forms an integral part of the regulations and reference tables. 

 

Pursuant to the laws and the regulations on safety on the workplace, failure to comply with the above-mentioned requirements results in both the manufacturer/importer who has not observed the EC regulations and the reference standards and the user who has not ensured compliance with all requirements necessary for the use of the lifting eye bolts and lifting eye nuts being jointly liable under civil and criminal law.

 

 

Our company has been renowned for its excellence in the manufacturing of lifting eye bolts and lifting eye nuts and for its attention to the safe use of lifting eye bolts and lifting eye nuts since 1954. 

 

In order to meet our customers’ needs we provide free of charge a duplicate of certificate 3.1 EN 10204 for each lot of lifting eye bolts and lifting eye nuts, in accordance with standards DIN 580:2018 and DIN 582:2018.

If the lifting eye bolts and lifting eye nuts’ instructions for use have been lost, damaged or have become illegible, the same can be downloaded free of charge here.

 

Lifting eye bolts and lifting eye nuts which have not been manufactured/imported in compliance with EC directives and which do not possess the mandatory operating requirements are available on the market. As well as constituting the offence of unfair competition towards companies that manufacture and/or market lifting eye bolts and lifting eye nuts in accordance with the mandatory operating requirements, this also infringes the laws and regulations on safety on the workplace.

 

If you have been sold such illegal types of lifting eye bolts and lifting eye nuts or if you know of any business selling lifting eye bolts and lifting eye nuts which do not comply with the mandatory requirements, you report the name of the dealer anonymously by filling out an anonymous report here.

We will verify the reliability of your anonymous report and forward it, with the relative documentation, to the competent authorities. 

As well as helping the European economy, you could also prevent serious injury or the loss of a life.

We wholeheartedly thank you for your co-operation.
