Platform Leveling Cylinder

The platform leveling cylinder keeps the platform
level through the entire range of boom motion.
The platform is maintained level to the turntable.
The ECM at the ground controls compares the
difference in readings between the platform angle
sensor and the turntable level sensor. The ECM at
the ground controls sends a signal to the platform
controls to open or close the appropriate platform
level proportional valve on the platform manifold
to maintain a level platform. The platform leveling
cylinder is equipped with counterbalance valves to
prevent movement in the event of a hydraulic line
failure.
How to Remove the Platform

Note: When removing a hose assembly or fitting,
the O-ring on the fitting and/or hose end must be
replaced and then torqued to specification during
installation. Refer to Specifications, Hydraulic
Hose and Fitting Torque Specifications.
1 Extend the boom until the platform leveling
cylinder barrel-end pivot pin is accessible.
2 Raise the boom slightly and place blocks under
the platform.
3 Lower the boom until the platform is resting on
the blocks just enough to support the platform.
Note: Do not rest the entire weight of the boom on
the blocks.
