Description

The invention is based on the subject matter defined in the preamble of claim 1.

• • unbeabsichtigte Abwärts- und Rutschbewegungen sowie
• • Geräte-Abkippungen auszuschließen,
• • eine gefährdungsfreie und sichere Arbeitstätigkeit des Bedieners zu gewährleisten,
• • einen waldbodenschonenden Bewegungsablauf durch eine entsprechende Komponenten-Ausbildung und Geräte-Arbeitsweise sicherzustellen, sowie
• • einen rationellen Arbeitsablauf, der möglichst nur einen Bediener erfordert, zu ermöglichen.

The use of forestry vehicles and other mobile equipment for thinning in mountain and slope forests with different steep forest soils requires a specific training and structure of these tools to

• • unintentional downward and slipping movements as well
• • exclude device tilting,
• • to ensure a safe and safe operation of the operator,
• • To ensure a forest floor-friendly motion sequence through appropriate component training and device operation, as well
• • To enable a rational workflow that requires only one operator if possible.

In order to meet these requirements in whole or in part, the known state of the art is characterized by a wide range of different types of mobile work equipment used in forestry companies and forest farmers in mountain and hillside forests. A number of innovative product design variants are also the subject of invention applications. By way of example, this prior art will be described and evaluated with the patent and utility model documents mentioned below.

The inventive features named in the claims are therefore based on the problem of innovatively designing a mobile working device for slope forest thinnings in such a way that the named disadvantages are avoided in the future. As a result, all the required functional components for a forest-friendly thinning already felled and on the Forest soil near and distant trees and branches rationally debugged, separated in round logs and fed directly to a collection point below, complex innovatively and inventively trained and arranged.

This complex problem is solved by the patent claim 1 as follows:
The chassis of the mobile implement is equipped with four, hydraulically operated by an all-wheel drive and by separate wheel joints, moving drive wheels, which are small, wide and designed with a pronounced Umfangsprofofilierung. By means of a pivotally mounted about a ball joint and supported by hydraulic support cylinders asynchronously, at different heights to the chassis and pivoted in a horizontal position carrier plate is a continuously pivotable about a vertical axis crane column equipped with a tree trunk gripper articulated timber transport crane, vertical held, positioned.

At the valley-side facing front side of the chassis are on a U-shaped, open discharge chute, on the directionally flexible juxtaposed channel-individual elements, rested, separate and machined round logs, slipping down the valley, derived. In addition, the claims 2 to 4 include inventive embodiments, the

The invention is illustrated application-related to an embodiment in the figures simplified and explained in more detail in the following part of the description. Shown in

1 a view of the mobile implement in a hillside forest with steeply rising forest floor and

2 a side view after 1 as a plan view of the in-work position mobile implement

From the operator 5 , who always stays at a safe distance next to the mobile implement, this motorized mobile implement is radio-controlled in a steep and sloping hillside of a mountain forest in the intended working position, positioned and locked. For that are the four drive wheels 1.1 on the chassis 1 of the working device with all-wheel drive 1.2 and wheel joints 1.3 fitted. The drive wheels 1.1 are small in size, wide and formed with a pronounced circumferential profiling. The chassis 1 is, directed on the mountain side, with a winch 1.4 equipped over which the implement is anchored by means of locking ropes on mountainous standing forest trees or stumps. During felling, picking up and taking away fallen fell trees and branches by pulling rope device 4 from rope loop 4.3 , from pulling rope 4.1 and winch 4.2 on vertical crane column 3.1 consisting, as well as nearby trees by means of the vertical crane column 3.1 swiveling multi-articulated timber transport crane 3 and tree trunk claw 3.5 the implement is stationary and stationary.

This avoids tipping and overturning hazards caused by driving and joint movements in the slope forest, as well as forest floor tipping and damage. This is also due to the constant vertical positioning of the timber transport crane 3 over its vertical crane column 3.1 , by means of a ball joint 3.3 opposite the support frame 2 of the chassis 1 Tilted into a constant horizontal position and from support cylinders 3.4 supported support plate 3.2 additionally guaranteed. Thus, a significantly higher device safety compared to many alternative products of the prior art can be achieved. Opposite arranged and functioning are the functional assembly movements of Zugseilvorrichtung 4 and the timber transport crane 3 ,

On the chassis 1 is between the drive wheels 1.1 arranged, the delimbing and Rundholzbearbeitungsgerät 2.1 and the feeding device for on the downhill end side of the support frame 2 attached discharge chute 2.2 grown and grown. The discharge channel 2.2 consists of a, due to the distance storage to the storage area at the foot of the mountain or hillside forest arranged collection number number of gutter-individual elements 2.3 , The strained and separated roundwoods 3.6 then automatically slide by gravity to this collection point down. For the not shown in the figures central hydraulic pressure oil supply of all functional components is on the chassis 1 a hydraulic pump and the hydraulic tank 1.5 arranged. These as well as the movement and steering of the drive wheels 1.1 are dependent on the situation by the operator 5 , cable or radio remote controlled, actuated.
