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.
