10.3 Manual release
•
Required standard
It is essential that the manual release for the lift is in sound condition. The manual release procedure should be
both displayed clearly within the upper floor controller and in the customers user guide. Follow these instructions
ensuring that the system works smoothly and that power is removed from the lift.
•
Required action
If the release system is not working correctly and any immediate remedial work cannot be complete, inform the
customer and supervisor on future work required and that the lift should be taken out of service.
10.4 Rope connections and wear/stretch
•
Required standard
All rope connections must be checked, counterweight, sling and overspeed governor. These connections MUST be
of quality nature and secured with a double nut and split pin. Also check rope grips are tight, with the saddle
section sitting against the working side of the rope.
Any springs used must have no damage present and be even in compression. Check there is no twisting present in
ropes and that any steel work supporting a rope connection must be clear of damage or stress.
Determination when the ropes should have to be discarded must be either,
- According to DIN 15 020, 6 broken wires within a length of 6 x d (36mm overspeed governor and
30mm suspension ropes)
-
As specified by supplier, with a reduction of 6% (0.36mm overspeed governor and 0.3mm suspension
ropes)
Rope plate should be clearly visible at the rope connection point on the sling pick up beam (
Figure 1 - Rope data
plate
).

Finally, check for rope stretch. The ultimate limit switch should operate before the counterweight comes into
contact with the pit buffer.

Required action
If there are any nuts, rope grips or split pins absent replace if possible and make note on log card. Clear any light
corrosion on terminations. If any spring, eyebolts etc… are damaged make note of manufacture and part number
and inform supervisor and customer on required remedial work.
If any ropes are not to the required standard, terminals are pulling through steel work or connections have
excessive corrosion the customer and supervisor must be informed that the lift will need to be taken out of service
immediately.
