Maximum capacity
The total hydraulic oil displacement for the version R755 is 287 lit/min
The total hydraulic oil displacement for the version R755 H is 417 lit/min
Main control valves
The main pump feeds the 3 hydraulically piloted control valves, the control valves are equipped
with a maximum pressure valve located at the inlet and with anti-shock and anti-cavitation
valves on all sections. The control valves control the boom cylinders, the rotation and the
motion functions.
Secondary control valve
1 electrically actuated control valve, that receives the oil from the secondary pump, controls
the under carriage functions.
Boom cylinders
All the boom cylinders are of double effect type and are equipped with end stroke shock
absorbers in both directions. The cylinders of the inner and outer boom can be equipped with
locking valves (Standard ISO 10567).
Under carriage cylinders
All the under carriage cylinders are of the double effect type and are equipped with locking
valves.
Operator's cab
The cabin is made out of steel and is installed on shock absorbers.
The cabin is safe against overturning and is verified with following standards:
•
ROPS structure following the ISO 3471 standards
•
FOPS structure of 1st level following ISO 3449 standards
The cabin can be tilted hydraulically for maintenance purposes.
The windows, in tempered and colored glass, are of big dimensions and permit full visibility on
the working area. The windows have the following openings:
•
Front window tilts inside (no external overhang).
•
Side opening window
The operator's seat can be adjusted and is constructed in order to minimize the vibrations. The
seat is equipped with safety belt and headrest
