FITTING ACTIVE HYDRO-PNEUMATIC SUSPENSIONS FOR PANORAMIC
PROCEDURE
The active hydro-pneumatic suspension system ensures better comfort for the operator in the cab while driving a medium-high
speed and at the same time improves machine road-holding while also protecting the mechanical structures and the load
carried against blows caused by road bumps and travel over irregular ground.
It is also advised to use these suspensions for transporting loads over irregular ground since the active system is designed to
adapt to the weight carried (from 0 to MAX) without affecting ground clearance .
When loading-unloading materials on flattish and firm ground (e.g. asphalted depots), it is advisable to deactivate the active
hydro-pneumatic suspension system to ensure better working precision.
OPERATING INSTRUCTIONS
The system envisages two user modes - MANUAL and AUTO - selected using
selector switch "S". (Fig. 1)
in MANUAL mode, it is possible to perform commands involving the crossways
tilt corrector.
Movement is obtained by pressing buttons "P1" and "P2" and halts automatically
when these buttons are released. The command must only be given with the
machine at a standstill. (Fig.2)
P1 = anticlockwise chassis levelling
P2 = clockwise chassis levelling
IMPORTANT! In MANUAL mode, if the machine boom is raised
beyond the locking device intervention limit, operation of the crossways tilt
correcter is prevented.
In AUTO mode, the suspension effect as such is obtained, ensuring maximum
driving comfort during trips with and without loads.
By turning the selector switch "S" into position AUTO, the machine presets for
this operation; if all safety conditions are respected, a led comes ON, the
suspension is activated and jacks "M" slide out by approx. 40mm. (Fig.3)
In AUTO mode, the suspension activates itself only if:
-
the machine boom is not raised beyond the lock device intervention limit
- crossways chassis movement is in the central position (indicator light 56
OFF).
If these safety conditions are not upheld, the led does not come ON and the
suspension is not activated. In the event of system faults, contact Merlo
Technical Assistance service.
WARNING!!
If, when turning selector switch "S" into the AUTO position, the jacks do not slide out or slide out incorrectly, contact
Merlo Technical Assistance Service.
When the machine is fitted with active suspensions on the front axle (EAS), it is not possible to perform crossways
levelling operations at full load but exclusively with a maximum weight of 3000Kg.
If absolutely necessary, it is possible to perform crossways machine levelling with loads greater than 3000 kg by
performing complete movement in advance of the part opposite to jack "M" which is to be lifted.
Make sure that machine is correctly levelled before attempting any lifting operations.
Pay careful attention when activating/deactivating the suspension system since the machine is raised/lowered by
about 40mm.
Load handling on uneven surfaces is permitted by using frame levelling device to level the machine chassis to the
proper position. Check correct levelling using the spirit level in the cab.
PERIODICAL SAFETY CONTROLS
Check the calibration of the hydro-pneumatic accumulators every 1000 hours.
This operation must be carried out by Merlo Technical Assistance Service.
