By inspections I'm referring to operator checks.

Hello Brendon,I'm guessing you've taken a look at the Acop for cranes?
3.2 Routine Checking
Every controller of a crane shall ensure that:
(1) operators carry out appropriate checks to enable the crane to be operated
safely, according to the controller’s written procedures based on the
manufacturer’s instructions where available, and that the controller can
demonstrate that the checks have been carried out
(2) the controlled range feature, where fitted on radio-controlled cranes, is
tested at suitable intervals, and that at the beginning of each shift, or
where there is a change in the crane operator, the controlled range is
checked to ensure that it is in accordance with the limits specified for its
operation.

Yes - looked at the ACOP. Interested in the frequency :)

I would think these would be done each time an operator went to use the crane?

Thanks for your response. The checks I am referring to are documented checks rather than a pre-operational visual check.

If you can (i.e. they are still in business) I would be asking the manufacture for advice rather than an internet forum (although I assume your question is more to gauge what is normal than specific advice). If you can't contact the manufacture, then you may get some good advice regarding periodic maintenance and checks from someone at the Maintenance Engineering Society of NZ (https://mesnz.org.nz/).

rather than "documented checks" the better evidence would be to have a (working) Preventative Maintenance program and the proof being maintenance work records (e.g. work orders or POs) to inspect/identified, and carried out maintenance work as required.
(I am assuming that the gantry crane has a current certificate of inspection, and your question is regarding what is practical above the minimum statutory requirements)

The operator should do a daily check that looks at the condition of things like the changs (visabale wear etc) and any of the lifting gear as well as the remote. as for the ganty itself, i have always erred on the side of not having an operator check the ganrtry itself rather implamenting a regular maintainence and complaiance regime to capture any fulats there.

By the 2 fold approch you are giving ownership to th operators for the equiment and ensuring that they check it (just make sure it is not a tickbox!) and then the wrap around of the maintainence by a competant and qualified professional to by service the equipment and certify the lifting equipment use.

Hope this helps!

As per the Acop, what do the makers of the cranes that you are using recommend? You are responsible for developing the checks and frequency to suit your situation and providing the documentation.

You need to follow numerous duties under the PECPR Regs; as this is a legal requirement, I suggest you start here.
As far as 'required' inspections, you need to have a current certificate of inspection, commonly known as an M&I certificate. These are valid for 12 months.
Any other inspections are as you decide, such as frequency and content.
Go to the Crane Associations Shop - they have a Gantry Crane inspection book available to buy

I had a similar issue at my last workplace but I couldn't get management on board unfortunately but I did find a recommended schedule depending on hours of operation on the Monocrane website as follows:

I hope it helps.

send me your email address I have a few versions that may suit your sitaution

Hi Brendon
I also have gantry cranes in my workshops.
These are inspected every morning, by an apprentice
Maintained by Vermissimo on an annual basis
Inspected and recertified annually by SGS.

I have some samples of daily crane checklists if you want them.
