Abstract

The invention concerns a system for the processing and transport of forestry material by means of terrain-going vehicles (1A, 1B) such as forestry machines and where the material, after harvesting, is intended to be transported from the felling site (5) to consumers. In order to achieve improved efficiency, the system includes a vehicle combination consisting of; a) a first vehicle (1A) that can be driven and that is equipped with a driver's cabin (15) and supports a harvester unit (3) at a free end of a crane arm (2) that can, through operation of the crane, carry out harvesting within a practical working area (17) within a defined working sector, b) a second vehicle (1B) without a driver's cabin (15) that supports a timber-receiving unit (11) at a crane arm (10), and which second vehicle is provided with a load compartment (12) for the transport of tree trunks, c) coupling means (14) with which the second vehicle (1B) can be coupled to the first vehicle (1A), d) a loading system that, through it being arranged to reach into the practical working area, allows the timber-receiving unit (11) to receive and carry timber in a retaining manner directly from the harvester unit (3), and to displace timber to a position in and above the load compartment (12).

Abstract

The invention concerns a mobile load compartment (3) for logs from young forest during thinning and intended to be coupled in a jointed manner behind a harvester of the type that demonstrates a front assembly (1A) and a rear assembly (1 B) that are united through a joint (8) in a manner that allows pivoting and where the rear assembly is equipped with a driver's cabin (2) and the front assembly with a crane (10) that can be rotated around a vertical axis (Z1 ) and, supporting a harvester unit (20), can be used for the gripping and handling of logs, a loading arrangement arranged at the said mobile compartment and including a timber receiver (26) in order to receive the said logs and support them in a retaining manner. In order to obtain a higher degree of exploitation, a loading arrangement is arranged to receive a log directly from the harvester unit (20) and to retain it, and - independently of the motion of the harvester unit - to carry out displacement using the crane (10) of a delivered log to a position in and above the said mobile load compartment (3), whereby the loading arrangement is arranged to receive a log from a position within the working area (25) of the harvester unit in front of or at the side of the front assembly (1 A) of the harvester.
