Design working period assessments (DWP)
Crane owners are frequently and incorrectly advised of the need to undertake 10-year and 25- year inspections, despite these inspections having been redundant for 5 years and thus not necessary.
The current requirements are that a DWP assessment be undertaken no later than 7 years of age to determine where the crane and hoist are within their design duty. A major inspection and major assessment are not required if the DWPs of the crane and hoist have been assessed as less than 100%.
The Design Working Period (DWP) represents the design duty of the crane and hoist. AS 2550.1-2011 refers to DWP as a "proven estimate of a safe operational life", so compliance with this requirement is strongly recommended.
Crane specification
The most important step in minimising cost over the life of the crane is adequate classification. Stanton's classification process ensures that your crane will last the expected duration whilst also minimising maintenance costs.
Our RFQ process sets the industry standard and provides a specification that captures all relevant requirements of the relevant Australian Standards (AS 1418.3-1997 and AS 1418.1-2002).
Fatigue assessment of crane structure / runway girder
For cranes that have surpassed their DWP and cannot be replaced due to grossly disproportionate cost to the business, our experienced team at Stanton can carry out a detailed fatigue analysis to determine the actual fatigue life of the crane, which is usually significantly greater than the nominal design life, hence certifying the crane for continued use for an extended period of time on the basis of the results obtained from the detailed fatigue analysis.
Our team of experienced engineers are also well equipped to carry out fatigue life assessment of crane runway girders along with assessment of adequacy of girder tie-backs and rail fasteners.
Periodic third-party inspection (PTPI)
Clause 7.3.4 of AS 2550.1-2011 requires that “Each crane shall undergo a periodic third-party inspection to provide independent advice on whether the level of maintenance and repairs are in accordance with
[AS 2550.1-2011]”.
Stanton have a team of qualified, highly competent and experienced personnel capable of carrying out PTPI inspections of cranes and providing independent feedback to crane owners regarding the crane's current condition and adequacy of maintenance. Stanton also incorporates an assessment of compliance. In addition, Stanton assesses all risk factors and on that basis determines the required frequencies of routine inspection and PTPIs for the crane.
Anti-derailment assessment and design
Whilst adequate anti-derailment has been required since 1960, it is rarely provided. Following a related fatality, this is an area that is now receiving significant attention. Anti-derailment forces are much larger than other lateral loads and design of anti-derailment is a highly specialised field.
Stanton has a team of experienced engineers who are industry leaders in this area and who can assess the adequacy of any existing anti-derailment provisions on cranes as well as design anti-derailment for cranes which do not have adequate anti-derailment.
Structural condition assessments
At Stanton, we provide in-depth structural examinations of ship-to-shore, rail mounted gantry (RMG) and rubber tired gantry (RTG) cranes. Our rope access methods enable cost-effective inspection of the largest ship-to-shore cranes without costly EWPs or large mobile cranes.
We also deliver structural intergrity inspections specfic to your needs for a wide range of plant including:
-
stacker reclaimers
-
bins
-
lifting devices
-
racking
-
industrial buildings
