If the air gap within the brake requires adjusting, this can be adjusted until it is acceptable. If for any reason the
brake cannot be brought up to a suitable standard the customer and supervisor must be informed on lift shut down.
13.2 Thorough clean
•
Required standard
Within the thorough clean it gives the engineer both a perfect chance to give everything within the lift a visual
inspection and also visually bring the lift up to the required standard.
14 5 YEAR MAINTENANCE CHECKS
14.1 Gearbox/motor detailed check
•
Required standard
In addition to the standard annual check a 5 year may be required. This will involve checking the backlash and
thrust of the motor. For this check the load must be removed from the motor by following these steps.
- Place packer beneath counterweight.
- Bring cabin to top floor using test control. Activate slow speed on nearing the top as counterweight will
come to rest on packer.
- Access the rear wall of cabin (
4.5 COP and rear wall removed, pg 5
)
- Using block and tackle, connect from the lifting bar to the sling and take the tension off the ropes.
- Use secondary safety brackets to fix sling back to shaft.
- Remove motor coupling from motor shaft.
- ENSURE LOAD IS TAKEN ON BLOCK AND TACKLE AND SAFETY BRACKETS.
With the load removed a standard check on the backlash and thrust.
•
Required action
If the thrust or backlash falls out of the required standard then a new motor/gearbox must be ordered and the
customer and supervisor must be informed that the lift should be taken out of service.
14.2 Earth bonding, insulation and electrical visual
•
Required standard
Ensure lift is first isolated and then check that metalwork enclosing live components, lift framework, lift carriage and
cabin metalwork is earth bonded to the main earthing terminal by earth protective conductors and of a value not
greater than
0.5 Ω .
Power circuits (select 500v test on meter). Turn off landing control station RCD. Test insulation to earth from both
the L & N terminals on the RCD ‘supply’ side.
Value should be greater than 5M Ω ?
Power circuits (select 500V test on meter). Turn off carriage mains isolation switch & unplug PL26 from the trailer
PCB. Test insulation to earth from both L & N terminals on the disconnected plug.
Value should be greater than
5M Ω ?
Check to see if RCD is present and operational and observe if the mains and control circuit voltage are within the
required tolerance (Mains 240
± 14.5V, control circuit 27 ± 3Vdc).
