74 Operator's manual ERCO X5000 CT LT PT2 FAST
EMERGENCY PROCEDURES
The lift has two emergency modes:
- MAIN LIFT MANUAL EMERGENCY
- BUILT-IN LIFT TABLE MANUAL EMERGENCY
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 cau-
tion: make sure that all persons are at a safe distance from the lift before proceeding.
Main lift manual emergency
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) move the control cabinet so that the hydraulic equipment is clearly visible;
4) press and hold down button
A on pneumatic solenoid valve YV6 so as to raise both
mechanical safeties;
5) if a mechanical safety device remains engaged, screw the handwheel C in the relevant
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 valve;
6) unscrew plug B1 of the hydraulic solenoid valve YV5. Turn anticlockwise the brass
pawl B2 of the solenoid valve;
7) operate alternatively the hydraulic solenoid valves YV3 and YV4 with the supplied
handwheel C, so that the misalignment between the two runways is never exces-
sive;
8) once the lift is completely lowered, release the pneumatic solenoid valve YV6 button
A;
then turn completely clockwise the brass pawl of the hydraulic solenoid valve YV5
and screw again its plug B1;
9) remove the handwheel C from valve YV3 or YV4.
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 7-8-9 of the procedure.
