User Manual FROG-9
Rev 05 Page14
Note 1: It is emphasised that users must not rely on these recommendations alone. Persons best placed to judge
the risk of specific transfers are the onsite personnel that have experience of the local conditions and
equipment to be used. All factors must be evaluated together in their pre-transfer risk assessment.
Note 2:
Crews must conduct dry runs without passengers if there are any concerns about conditions to help assess
risk of transfer.
Table 2: Other Operating Parameters
Parameter Recommendation
Wind Speed 30 knot (normal) / 40 knot (subject to assessment*).
* Feedback from the field indicates that all FROG models are very stable during high
winds and are considered suitable for operation in 30 knot winds. Transfers in 30 to
40 k
not winds are also considered to be acceptable, subject to RML’s
recommendation that operators must first perform the necessary risk assessments
and that trial transfers (without passengers) are used to confirm that controlled
lifting is possible, prior to the transfer of personnel.
Visibility Crane Operator should have a clear view of the pickup and set down
areas.
