Abstract
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.
