CAP: Autolevelling system for platforms
CAP control unit realizes the basket autolevelling function for an aerial platform.
According to the current regulations, basket inclination must not exceed 5° compared to the horizontal plane during the working mode; therefore all platforms should have systems to level the basket, manually or automatically.
CAP control unit detects deflections from horizontal plane and provides the outputs (on/off or proportional) to control the directional valve solenoids for basket levelling, in order to keep tilt into +/-5° range.
CAP control unit also provides one safety output (PL-d) to control a block valve, necessary to mantain the platform inclination under +/-10° maximum, in case of breakage of the main system.
