Lift Tape Condition
In this section the images below will show two types of lift tape condition, one in which the wear is
minimal and therefore in an acceptable condition, whereas the other Lift Tape has a level of wear
which is unacceptable and requires a change during the current service.
Acceptable Condition
It can be seen there is a very small amount of
wear to the tape but nothing substantial that
requires an immediate Lift Tape replacement. It
is advised the Service Engineer informs the
Customer of the dangers of Lift Tape fraying
and that they keep an eye on the tapes
condition.
Unacceptable Condition
In the first image you can see a clear increase in
wear with additional fraying. This is the start of
the Lift Tape starting the fraying process which
will only increase each lift. If the Lift Tape is
discovered in this condition or worse, at any
point along the tape, the Lift Tape should be
replaced immediately.
The second image is an example of extreme
wear which is a condition the Lift Tape should
never be allowed to reach. This condition is
endangering the safety of the patient.
