Abstract
An aerial device for operating on energized powerlines is disclosed. Embodiments of the current disclosure relate to a slew drive system for an aerial device. In some embodiments, the slew drive system provides leveling and jerk mitigation to an aerial platform of the aerial device. Various sensors may be disposed on an aerial device boom, on the slew drive, and on the aerial platform, for obtaining data indicative of a state of the aerial device. The data indicative of the state of the aerial device may be used to control the slew drive with various hydraulic valves and motors to level the aerial platform and mitigate/eliminate jerk. The systems and methods described herein provide a comfortable riding experience for aerial line workers in the aerial platform and maintain a level state of the aerial platform across a wide range of boom angles including at extreme ends of the boom assembly.
