Definitions
Transfer Lift
A transfer is defined as one pickup and put down when passengers are on board, or when
the unit carries more than its tare weight.
Usage Category
This is defined by the number of transfer lifts per year. There are four different usage
categories from low to very high.
Critical Parts
These are the identified set of load bearing parts.
Competent Person
A competent person is a person who has appropriate practical and theoretical knowledge
and experience of the equipment. This will enable them to detect defects and weaknesses
and to assess their importance in relation to the safety and continued use of the equipment.
It is recommended that the competent person is sufficiently independent and impartial to
allow objective decisions to be made.
Non-Destructive Testing
Although not considered necessary, some operators choose to carry out non-destructive
testing prior to any re-installation of a critical part.
If this is done, then a dye penetrant test should be used, as any other tests may produce a
false positive.
