2.3 Crane Transfer Planning Tool
We have developed a planning tool that can be used to determine whether the conditions
are suitable for transfers to take place.
Using the Crane Transfer Planning Tool
There are four main sections that need to be completed
i. Risk Assessment
ii. Pre-Transfer Checklist
iii. Passenger Log
iv. Post Transfer Review
The Crane Transfer Planning Tool can be found on the flash drive contained in your user
pack, or alternatively you can download a copy from our website.
It is important that the conditions are assessed prior to every set of transfers as conditions
are never exactly the same.
It is recommended that a trial run is always conducted as this provides real time feedback
on the conditions.
The operator should always refer to general guidelines on crane transfers operations to assess
overall risks.
If there is ever any concern about the conditions or the safety of the operations
transfers should be stopped.
