An overhead-line using system includes: a plurality of supports; a main rope supported by the supports and configured such that both ends of the main rope are fixed; a work rope movably supported by the main rope; a winding device configured to wind up the work rope; a moving device movably supported by the main rope and connected to the work rope, the moving device being movable in the air when the work rope is wound up by the winding device; and a power generator configured to move along with movement of the work rope. The power generator generates electric power by moving relative to the main rope.

The present invention relates to a grapple carriage for uphill, downhill and horizontal cabling of lumber and long goods. The carriage determines its absolute and relative position in space by means of a learning run or measuring run. During this run, a topographic ground profile and/or altitude profile is produced, and the position of the trees or long goods to be transported is analyzed. A central open-loop and/or closed-loop control unit processes all the machine status information which has been recorded and/or transmitted by the winch or yarder.

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.

A utility work device includes a main body section supported by a support and a working section supported by the main body section to perform a work on an object. The main body section is movable in a horizontal direction and a perpendicular direction.

The invention relates to a cable robot for creating a structure or manipulating a workpiece, comprising a working head which is suspended on a support structure having at least three support columns by a system of cables having at least three control cables, wherein cable winches are provided for adjusting the control cables relative to the support structure and/or relative to the working head, and they can be actuated by an electronic control device for moving the working head, wherein the support columns of the support structure are luffingly and/or telescopically arranged on a revolving stage, which has a ballast weight for absorbing a tilting moment introduced into the respective support column by the system of cables and which is arranged on an undercarriage such that it can rotate about an upright revolving stage axis, said undercarriage having a chassis and being configured such that it can move with the revolving stage and the downwardly luffing and/or retracted support column.
