Abstract

The hydraulic jack to fell trees in a desired direction consists of two steel levers pivoted together at one end with a hydraulic jack coupled between the free ends. The two levers at rest are in line with each other but as the jack is operated the two ends of the levers are gradually forced apart. The device is inserted in a saw cut in the tree on the opposite side of the trunk to the direction in which it is required to fall. USE/ADVANTAGE - As the levers open in the cut, the tree is forced to tilt and eventually fall where desired.

Description

Die Erfindung betrifft einen Baumheber zum Erzwingen einer gewünschten Fallrichtung beim Fällen von Bäumen.The invention relates to a tree lifter for forcing one Desired direction of fall when felling trees.

Beim Fällen von Bäumen ist meist eine bestimmte Fallrichtung vorgegeben um zu vermeiden, daß benachbarte nicht zu fällende Bäume beschädigt werden, und um das Rücken beim Abtransport zu vereinfachen.When felling trees, there is usually a certain direction given to avoid that neighboring ones not to be felled Trees are damaged, and around the back during removal to simplify.

Es ist bekannt, daß zum Erzwingen der gewünschten Fallrichtung bei leichtem Stammholz Keile verwendet werden, die in den Sägeschnitt auf der zur Fallrichtung gegenüberliegenden Seite eingetrieben werden und den Baum anheben und zum Fallen bringen. Bei schwerem Stammholz werden ebenfalls Keile verwendet, die aber oft nicht die erwünschte Anhebekraft aufbringen. In solchen Fällen wird der Baum mit Hilfe einer Seilwinde oder eines Greifzuges in die gewünschte Fallrichtung umgezogen. It is known to force the desired direction of fall wedges that are used in the Saw cut on the side opposite to the direction of fall be driven in and raise the tree and fall bring. Wedges are also used for heavy logs, but they often do not have the desired lifting power. In such cases, the tree is lifted using a winch or a grab train moved in the desired direction of fall.  

Das Fällen mit Seilwinde oder Greifzug ist zeitaufwendig, da das Seil einige Meter über dem Boden am Stamm angebracht werden muß um die entsprechende Zugkraft zu erzielen. Das Fällen mit einer Seilwinde ist kostenintensiv auf Grund der Maschinenabschreibung.Felling with a cable winch or grab is time-consuming because the rope is attached to the trunk a few meters above the ground must be to achieve the appropriate traction. The Felling with a winch is expensive due to the Machine depreciation.

Der Erfindung liegt die Aufgabe zu Grunde das Fällen mit Hilfe von Greifzug oder Seilwinde zu umgehen.The invention is based on the task of felling To bypass gripping rope or winch.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This task is carried out in a generic facility solved by the characterizing features of claim 1.
