10 MOUNTING THE PLATFORM & FINALIZING THE MECHANICAL WORK
10.1 MOUNTING THE PLATFORM TO THE LIFT ARMS
•
Mount the electric controls at this stage [see chapter 11], or at
minimum connect the battery and earth cables of the liftgate to
an external battery. This will help with manipulating the hydraulic
cylinders. Then proceed with mounting the platform.
•
Grease the 4 articulation points on the lift arm and the 2
articulation points on the tilt cylinders prior to mounting the
platform and pins. [Figure 10.1]
•
Lift up the platform (by forklift, hoist, overhead gantry crane…)
and bring it into position above the lift arms (in either a horizontal
or vertical position). Align the platform hands with the articulation
holes of the lift arms, mount the pins, and fasten their locking bolts
[see Figure 10.2
– 10.4].
•
Tilt the platform open to a horizontal angle.
•
Continue to support the platform by means of a forklift, hoist, or
gantry crane so you can continue working in the action radius of
the platform in safety.
•
Connect the tilt cylinders to the platform hands [see Figure 10.4].
The piston rods can be moved with the help of the regular electric
controls; or manually [see Figure 10.5] by:
1. Using the manual emergency operation on the safety
valves of the cylinders
2. Unscrewing the flexible oil pipes beside it (in order to avoid
vacuum forces)
3. Then push and pull the piston rod by hand
WARNING
•
See the USER’S MANUAL to check on the correct procedures for
manipulating the safety valves.
•
If the electric controls are being used to move the cylinders, proceed with
care. The cylinders might contain air, and can therefore react with
unforeseen characteristics.
•
Secure the pins of all articulation points firmly by means of locking bolts
(supplied with the liftgate) and pressurize cylinders gently.
