  • Rotary support systems, associated control devices, and methods of operating the same
    Patent number: 10550993
    Abstract: Rotary support systems, associated control devices, and methods of operating the same. Rotary support systems include a mast configured to support an elevated device and a base that includes a rotary mechanism that rotatably couples the mast to the base. The rotary mechanism is configured to selectively rotate the mast. The mast has a cross-sectional profile that is non-circular. Rotary support systems additionally may include a controller configured to interface with an electric motor to rotate the mast with respect to the base. Controller implemented methods for operating a rotary support system include receiving an input command and, responsive to the receiving the input command, sending an output command to an electric motor to rotate the mast relative to the base.
