Emergency Procedures - Corghi ERCO X4300 Serie Betriebsanleitung

EMErGENCY prOCEDUrES

The lift has two emergency modes:
- MAIN LIFT MANUAL EMERGENCY
- BUILT-IN LIFT TABLE MANUAL EMERGENCY ----- for version with LT only
These two modes are intended for handling emergency situations which may arise due
to malfunction, incorrect loading, power failure, etc..
The purpose is to enable the operator to retract the runways of the lift in order to allow
for removal of the vehicle.
Emergency procedures may be executed by the user, but we recommend contacting our
technical service department to clear up any uncertainties first.
Emergency procedures are potentially hazardous and must be executed with extreme
caution: make sure that all persons are at a safe distance from the lift before proceeding.
To lower the main lift in the event of a power failure, proceed as follows:
1) turn off the master switch;
2) open the control unit door;
3) press and hold button A on pneumatic solenoid valve YV6 to raise both mechanical
safety devices;
4) if a mechanical safety device remains engaged, tighten the handwheel C (located on
the right hand side of the base block) on solenoid valve YV3 (for the RH runway) or
YV4 (for the LH runway). (see figure17).
Operate the manual pump pM so as to raise the lift sufficiently to disengage the safety
pawl.
If the other mechanical safety device is hooked too, repeat the same operation by
screwing the handwheel C in the other solenoid valv;
5) unscrew cap B1 of the hydraulic solenoid valve YV5. Turn anticlockwise the brass
adjuster screw B2 of the solenoid valve;
6) operate alternatively the hydraulic solenoid valves YV3 and YV12 with the supplied
handwheel C, so that the misalignment between the two runways is never excessive;
7) once the lift is completely lowered, release the pneumatic solenoid valve YV6 button
A; then turn the adjuster screw B2 of the hydraulic solenoid valve YV5 fully clockwise
and re-tighten the cap B1 covering the screw;
8) Remove the handwheel C from valve YV3 or YV12 and return to its original position.
WARNING
Never leave a manual emergency operation on hold as the lift could slowly misalign.
Stop or cancel the manual emergency operation, if necessary.
Always carry out points 6-7-8 of the procedure.
