Practical Engineering offers
a 10 year crane inspection service.This
is completed in conjunction with a servicing workshop of the client’s choosing
or one recommended by Practical Engineering.
According to
Queensland Legislation (Mobile Crane Code of Practice, 2006) and the Australian
Standard (AS2550 & AS1418) a crane must be inspected by a professional
Engineer (defined in the legislation as an Engineer with CPEng, RPEQ or NPER,
with appropriate crane experience).
The Practical way…
How it happens:
Before the
service:a qualified Practical
Engineering visually inspects the crane for possible defects and areas for the
workshop staff to concentrate on.The Engineer
will check the maintenance logs and, if possible, contact the manufacturer for
a service recommendation list.
The
service:The Practical Engineer is
involved in inspecting the strip down, service and reconstruction of the crane.
After the
service:Once the crane has been
serviced and reconstructed, a second visual inspection is undertaken to ensure
correct reconstruction and servicing.A
load test is completed to examine the functionality, stability and that
everything is in safe, working order.
The
certificate:If all is completed and
tested to the Engineer’s satisfaction, the certified Engineer will then issue the
certificate.
Why Practical? The Practical
difference is we design lifting equipment which gives us expertise and
experience.We have qualified Engineers
who are recognized as fully competent under the legislation to perform these
inspections and issue certificates.
Certify custom lifting equipment – including lifting lugs and pad eyes
Advise testing, maintenance schedules and inspection periods
Provide guidance and design
What needs to be certified…
If the lug is used in a lifting, hoisting or a winching action – it must be certified.
If used in an application where its failure could result in serious injury or death, the lug needs to be certified.
If used in an application which could result in any injury – the situation needs to be at least checked by a qualified engineer.
If in doubt, seek guidance.
Applicable standards…
There are no Australian Standards specific to lifting lugs and pad eyes, however there are a number of standards that discuss the lug requirements and safety considerations.The following is provided as an indication of some of the applicable standards and not as a comprehensive list.
AS4991 Lifting Devices
AS1891Industrial Fall Arrest
AS1418 Cranes, Hoists and Winches (Crane Code)
AS4380 Cargo Restraint Systems
AS4744 Steel Shoring and Trench Lining Equipment
The specifics of the lug should be certified against AS3990 Mechanical Equipment – Steel Work and AS4100 Steel Structures.
What we need to know…
The material of the lug
Service – what does it do, expected load, frequency and duration of use (duty cycle), direction of load in relation to the mounting of the lug.
Basic dimensions of the lug.
The weld and quality of the weld.
Most importantly, the structure the lug is connected to.
Guidance…
Lifting lugs should be permanently marked with the applicable information
For lifting, hoisting or winching – either WLL (Working Load Limit) or SWL (Safe Working Load).
For lugs used for lashing – LC (Lashing Capacity)
It is good practice to assign a lug number to each lug – for the future identification of the lug (quality control measure).
The centre hole on a lifting lug should never be flame cut as if the lug needs to undergo NDT (Non Destructive Testing) the flame cut may leave flaws in the material.
In most instances, it is also a good idea to examine the structure the lug is connected to – as there is no use having a super strong lug attached to an unsuitable structure.
