Did you know that the crane lifting attachment that you have been using for the last 10 years possibly does not conform to the latest Australian Standard for Lifting Devices.
In 2004 Standards Australia released their design criteria for Lifting Devices under a new standard AS4991. The design criteria within this standard expects that your lifting attachment can withstand a “proof load” of 2 times the unit’s working load limit (WLL) up to a load capacity of 10 tonne.
Therefore if you are designing and manufacturing a crane bin to lift product onto a high rise building site, that is rated to 2000Kgs WLL, then the unit must be tested to 4000Kgs.
The unit MUST have been engineered, designed and drawn and then manufactured by tradesman that can perform welding tasks to AS1554.1sp, and finally “proof loaded” as the last test for it’s capacity rating.
If these steps have not been done, then there is a fair chance that your lifting device will not conform and you could run the risk that the unit fails and injures someone in the process, or worse still you could end up with a death onsite.
Bremco is proud to say that we follow the above steps when designing and manufacturing your crane lifting attachment or device, including our specialised crane lifting cages, and although it may cost a little bit more upfront – you can be assured that the unit will meet all the requirements of Australian Standard AS4991 (Lifting Devices).
Please discuss your design requirements with the team at Bremco next time you are looking at that new crane lifting device.
