A transportation system capable of preventing or minimizing limitation of a transportable range in a three-dimensional space is provided. A transportation system for transporting a transportation object in a three-dimensional space includes a container configured to be suspended by a vertical wire, a container support unit configured to support the container with the vertical wire interposed therebetween, at least three support columns, a vertical actuator configured to wind and unwind the vertical wire, a horizontal actuator configured to wind and unwind a horizontal wire stretched between the support column and the container support unit, and a control apparatus configured to control the vertical actuator to thereby control a vertical movement of the container, and control the horizontal actuator to thereby control a horizontal movement of the container.

The lifting device includes a first drum around which a wire is wound, a first motor that rotates the first drum, a second drum around which the wire fed from the first drum is wound, and a second motor that rotates the second drum. The first motor is driven to rotate the first drum so as to lift the wire, and the second motor is driven to rotate the second drum to lift the wire fed from the first drum.

A collection method using a collection system including a lifting device that is configured to wind up an overhead line supported by a support post, a suspension device that is connected to the overhead line and is movable in the air as the lifting device winds the overhead line, and a grip device suspended from the suspension device includes a step of gripping a tree by the grip device at two points, a step of cutting the gripped tree, a step of tilting the cut tree such that a longitudinal direction of the tree is along a horizontal direction, and a step of conveying the tree gripped by the grip device as the lifting device winds the overhead line.

An aerial navigation system comprises upright members mounted with anchor points at a substantially same height. Each anchor point is provided with an electric motor. A carrier device is coupled to the electric motors at corresponding ones of the anchor points using a set of first wires. The carrier device is operably moved by the electric motors in a horizontal plane co-planar with the anchor points. Further, a robotic device is suspended from the carrier device using a second wire. The robotic device is moveable within a volume defined between a ground surface, the plurality of upright members and the horizontal plane by at least one other electric motor mounted on the carrier device. Furthermore, a navigation control system synchronises operations of electric motors at the anchor points and the carrier device for moving the robotic device from a current location to a target location within the volume.

A load transport system having a load carrier and at least one load receiving device which for receiving the load is fastened to the load carrier, and at least three positioning cables and at least three suspension devices, each suspension device has at least one positioning cable winch for winding and unwinding one of the positioning cables. The load carrier is suspended from the suspension devices by the positioning cables. The load carrier and the load receiving device fastened thereto are relocatable by activating the positioning cable winches, and the load carrier has at least one multi-cable suspension to which at least two of the positioning cables are connected via cable connectors. Each of the cable connectors is mounted on the multi-cable suspension to be pivotable about at least two pivot axes aligned to be mutually orthogonal, and all pivot axes of the cable connectors intersect in a common intersection point of this multi-cable suspension.

A skyline log conveying system having a skyline for extending between two elevated supports, one at or above a landing at which logs are deposited and another at a lower position at least as low as an area from which logs are to be moved. A carriage is rollably mounted to the skyline. A grapple is suspended from the carriage, the grapple having closed and opened positions for grasping and releasing logs. A hydraulic pump is mounted to the carriage. A rotatable member is driven by the skyline with the rolling of the carriage on the skyline for driving the hydraulic pump to generate hydraulic pressure. At least one accumulator is in hydraulic communication with the hydraulic pump, the at least one accumulator capable of storing pressure when hydraulic pressure is transmitted to it by the hydraulic pump. A hydraulic ram is hydraulically interconnected with the at least one accumulator and mounted to the grapple to selectively close the grapple to facilitate the grasping of logs.

The disclosure is directed at a robotic platform for use in large workspaces. The disclosure includes a moving platform that is controlled by a set of cable actuators via a set of cables. The cables are also connected to at least one of a counterbalancing and/or a counterweight system to reduce the impact of forces being experienced on the moving platform on the set of cable actuators. In one embodiment, at least two of the set of cable actuators are connected with a single closed cable loop.
