Abstract
A multi-axial mast positioning system includes a frame having two opposed vertical sections, an axle coupled to the frame and rotatable around a first axis passing through the opposed vertical sections of the frame, and a mast coupled to the axle and rotatable about a second axis aligned with and perpendicular to the first axis. Level sensors measure the orientation of the mast along the first and second axes.
Claims7
A multi-axial mast positioning system comprising:
- a frame having first and second opposed vertical sections;
- an axle having a first and second end, the first end rotatably coupled to the first vertical section of the frame;
- a first rotary actuator coupled between the second vertical section of the frame and the axle so as to rotate the axle;
- a mast having a plurality of telescoping sections extendable from a base section along a longitudinal axis thereof;
- a second rotary actuator attached between the base section of the mast and the axle, the second rotary actuator attached to the base section at an intermediate position along the length of the base section and at a single point along the axle at a position essentially midway between the first and second vertical sections of the frame so as to tilt the mast about a tilt axis aligned perpendicular to the longitudinal axis of the mast.
