When selling fabricated attachments with Lifting Eyes, there are three levels of Certification that Calibre Contracting Equipment can provide in relation to the SWL stamped on the Attachment, as follows;
1. Certification of Design of Lifting Eye welded to Plate.
NOTE - This is not certification of the Lifting Eye on the particular Attachment being sold to the Customer – and would not comply with the requirements for certification if the lifting eye is to be used as a “Crane”.
This level of Certification is verification that the design of Lifting Eye welded to Structure (Multi-Coupler, Actuator Tilt base) has been examined by a qualified engineer. The Engineer is verifying that all necessary calculations and analysis have been done on the Design of Lifting Eye onto the Plate it is welded to - and if the manufacture has been properly done in accordance with the design - then the Lifting Eye welded to the plate should be suitable for the stipulated SWL.
It should be noted that this is the level of “Certification” being provided by most suppliers in the market place.
2. Certification of Design of Lifting Eye and Attachment to Dipper Arm.
NOTE – This is not certification of the Lifting Eye on the particular Attachment being sold to the Customer – and would not comply with the requirements for certification if the lifting eye is to be used as a “Crane”.
This level of Certification is Verification that the design of the lifting Eye to the Structure (MultiCoupler, Actuator Tilt Base) and design of the Attachment Structure - itself, has been examined by a qualified engineer. The Engineer is verifying that all the necessary calculations and analysis have been done on the Design of the lifting Eye and the Attachment itself – as they connect to the Dipper Arm – and if the manufacturing has been done properly in accordance with the design of both the Lifting Eye and the Attachment - then the Lifting Eye and Attachment, as attached to the Dipper Arm should be suitable for the stipulated SWL.
This is Calibre’s standard level of Certification and a copy of this Certificate is available on request.
This is compliant to AS4772-2008 which is the relevant regulation governing Earthmoving Machinery compliance in Australia and New Zealand.
It should be noted that a very small few suppliers in the market place provide this level of “Certification”.
While it is not certification to a level under the Cranes regulations, it takes the customers attachment one step closer to proper certification should the customer later decide to get certification suitable for the Lifting Eye to be classified as a “Crane”. It should be noted that retro-certification is a very expensive process due to the analysis work that has to be done on the specific attachment, before an appropriate certificate can be issued.
3. Certification of Compliance for Specific Attachment.
This level of certification is the only level of certification that will enable the customer's attachment to be properly certified under "Crane Regulations".
This level of certification is done to quite a different level to the above two levels. The design is already approved. However for certification of the particular attachment, it is necessary for the engineer doing the certification to supervise the manufacture, welding and assembly process of the particular attachment.
Naturally, there is more time and expense involved in this process. Under Calibre’s manufacturing techniques, most of the extra expense and time is in making the attachment under supervision and in the engineers certification charges.
Provided the customer orders this level of compliance in advance, the extra cost is $600.00. It should be noted that retro certification after completion of manufacture is not really an economical proposition for customers.
None of the “Standard Certifications” of suppliers in the market place – that we have seen - provide certification to this level.
THE CUSTOMER SHOULD BE SATISFIED THAT THE LEVEL OF CERTIFICATION BEING PROVIDED MEETS THE CUSTOMER'S REQUIREMENTS FOR CERTIFICATION AT TIME OF ORDER.
