Major inspections are required under the following circumstances. Our view is that a load test can be a valuable tool to mitigate risk and should be completed if practicable. Show results 1 – 10 of Test travel and traverse motions at full speed to ensure load is controlled. What are the critical elements of a major inspection? For example, Defects found during the pre-operational inspection shall be recorded in the logbook and reported to a responsible person.
Should the crane owner inspect or maintain the crane at a frequency interval greater than recommended by the manufacturer or the competent person, then a thorough risk assessment of the rationale and control processes shall be conducted, implemented and audited to ensure compliance.
Mounting bolts secure Hoist emergency brake, if fitted- condition pads or shoe, adjustment and operation to ensure brake engages promptly. The frequency of inspections is subject to variances in the extent of usage of the crane s and engineering judgement. Rails- minimal say 3 -5 mm maximum burring of rails heads, rails clips are in place and tight, snug blocks in place. Generally, in the first 6 years of the runway life there should be no problems.
Structure Bridge girder box construction- connection between top flange and web, especially in the middle quarter of the span- cracking. What are the critical elements of inspections? Hooks- rotate freely, no evidence of cutting or wear in bight of hook, no evidence of cracking in the hook body to shank under nut. Crane runways and monorails by Standards Association of Australia.
This is the default dialog which is useful for displaying information. An interpretation of this is that the company or employer must ensure that they have taken all reasonable steps to make sure that personnel who are performing work on overhead cranes have been adequately trained. Gearboxes- gearbox has oil and condition of oil- recommended periodic oil samples are taken to test for presence of wear particles for gears. Requirements for cranes subject to arduous working conditions by Standards Association of Australia.
The safety factor ranges between 1.
Cross travel cross beam lower flanges for damage or cracking and connections to end carriages. To apply the calculations described in AS The only method of duty estimation that does not require DWP to be reduced by a factor of safety is using an automatic data recording system.
The key objective of the Major Inspection is to assess the viability of upgrading the crane to the requirements of the Australian Standards. If the limit has failed and a collision should occur, significant damage to the crane structure would result.
Summary Load testing is a critical tool in ensuring crane safety.
While the rated capacity is held by the main hoist. These provide real-time data via a modem so equipment owners can log in and see exactly how their equipment is operating. A comprehensive range of new designed and manufactured products as well as reconditioned products are available to bring your old crane s up to modern standards of safety, reliability and operational performance.
Certification for continued safe use will therefore be subject to the crane conforming to the current Australian Standards.

The only method of duty estimation that does not require DWP to be reduced by ad factor of safety is achieved by using a recognised type of recording system such as Konecranes Control Pro. The requirements for checking whether critical dimensions remain within specified or acceptable tolerances should be established. Self-erecting tower cranes by Standards Australia.
It can be reasonably concluded that the minimum frequency aw service on any crane, hoist or winch in service, is quarterly. Iceage incorporate this strategy right from the start to save on ax costs of initial inspections. Inspections Pre-operational Inspection This is a visual inspection and functional test that should be carried out by a competent crane operator prior to each shift during which the crane is to be used.
Initial inspection frequency should not be greater than 2 years.
An assessment can be made on the actual duty being performed and then compare that to recommended maintenance inspection frequencies given in AS When completing a Major Inspection AS For crane railways and monorails, according to AS Loading and unloading 1. Test electrical system for voltage drop during simultaneous operation of the main hoist and travel under full load and acceleration.
Standards New Zealand 1. New provisions are introduced to this assessment. Data logging records containing state of loading, duration of operation and number of load cycles can be used to determine a more accurate inspection interval and avoid excessive effort spend on crane inspection.
Special inspection requirements for such areas should be specified by the designer, e. Section 9 of AS A continuous working record e.
Electrical Hoist limits, working and top limits. Routine Inspection and Maintenance Includes visual inspection of most components of the crane, functional tests of all motions and lubrication of all moving parts. Design and construction of workboxes 25550.1 Standards Association of Australia. Emergency functions- ensure operable. SA approved codes of practice In later life, the frequency may reduce to 12 or 6 months. The standard goes on to give an example of what a typical inspection and testing certificate may look like.
This will be based on the accumulated data and inspection records. For elements subject to excessive wear or corrosion, a schedule for their planned timely restoration or replacement should be established based on measured rates of deterioration.
