1. A guided lift system for maneuvering a payload, comprising:
- a lift unit attached to the payload;
a first control tether attached to the lift unit;
a first control unit adjustably coupled to the first control tether, the first control unit fixed to a first position and operative to adjust a length of the first control tether between the first control unit and the lift unit;
a second control tether attached to the lift unit; and
a second control unit adjustably coupled to the second control tether, the second control unit fixed to a second position and operative to adjust a length of the second control tether between the second control unit and the lift unit such that coordinated length adjustments of the first control tether and the second control tether via the first control unit and the second control unit controls movement of the lift unit and payload between the first position and the second position.

Abstract
Systems and methods provide for a guided lift system utilized for maneuvering payloads. According to aspects of the disclosure, a guided lift system may include a lift unit attached to a payload, at least two control tethers attached to the lift unit, and at least two control units fixed in positions and capable of adjusting the lengths of the control tethers. Coordinated length adjustments of the control tethers pulls the lift unit and payload in a desired direction to a desired delivery location.

15. A guided lift system for maneuvering a payload, comprising:
-
a lift unit comprising a lift vehicle and a payload tether attached to the payload; a first control tether attached to the lift unit; a first motorized winch assembly coupled to the first control tether, the first motorized winch assembly fixed to a first position and operative to adjust a length of the first control tether between the first motorized winch assembly and the lift unit; a second control tether attached to the lift unit; a second motorized winch assembly adjustably coupled to the second control tether, the second motorized winch assembly fixed to a second position and operative to adjust a length of the second control tether between the second motorized winch assembly and the lift unit such that coordinated length adjustments of the first control tether and the second control tether via the first motorized winch assembly and the second motorized winch assembly controls movement of the lift unit and payload between the first position and the second position; and a controller communicatively coupled to the first motorized winch assembly and the second motorized winch assembly, the controller operative to coordinate length adjustments of the first control tether and the second control tether to move the lift unit and payload. - View Dependent Claims (16)

17. A method for maneuvering a payload, the method comprising:
-
lifting a payload attached to a lift unit comprising a lift vehicle and a payload tether; at a first control unit at a first position, lengthening a first control tether attached to the lift unit; and at a second control unit at a second position, shortening a second control tether at a rate corresponding to the lengthening of the first control tether to pull the lift unit to a destination location between the first position and the second position. - View Dependent Claims (18, 19, 20)
