A system for the processing and transport of forestry material such as tree trunks by means of vehicles (1A, 1B) such as forestry machines that can be driven in terrain and where the material after harvesting, which includes the felling and cross-cutting of trees standing on roots, is intended to be transported without intermediate steps from the felling site to a central storage area at which the forestry material is intended to be delivered into a timber store located in connection with a road for its onwards transport with, for example, lorries to consumers, wherein the system includes a vehicle combination consisting of: a) a first vehicle that can be driven and that is equipped with a driver's cabin and that supports a harvester unit at a free end of a first crane arm that is arranged to be displaceable, which harvester unit can, through manoeuvring of the first crane arm, carry out harvesting within a practical working area of a defined working sector during the felling of trees, b) a second vehicle that demonstrates a lack of a driver's cabin and that supports a timber-receiving unit at the free end of a second crane arm that is arranged to be displaceable, which timber-receiving unit is intended for the reception and management of tree trunks, and which second vehicle furthermore supports a load compartment for the transport of tree trunks, c) coupling means with which the second vehicle can be coupled to the first vehicle, d) a loading system including the second crane arm and the timber-receiving unit, which allows, through the second crane arm being arranged such that it reaches into the practical working area, the timber-receiving unit to receive and carry in a retaining manner timber directly from the working area of the harvester unit and, independently of the movement of the harvester unit, carry out by the second crane arm the displacement of timber, which is transferred from the harvester unit within the practical working area, to a position in and above the load compartment. a) a first vehicle that can be driven and that is equipped with a driver's cabin and that supports a harvester unit at a free end of a first crane arm that is arranged to be displaceable, which harvester unit can, through manoeuvring of the first crane arm, carry out harvesting within a practical working area of a defined working sector during the felling of trees, b) a second vehicle that demonstrates a lack of a driver's cabin and that supports a timber-receiving unit at the free end of a second crane arm that is arranged to be displaceable, which timber-receiving unit is intended for the reception and management of tree trunks, and which second vehicle furthermore supports a load compartment for the transport of tree trunks, c) coupling means with which the second vehicle can be coupled to the first vehicle, d) a loading system including the second crane arm and the timber-receiving unit, which allows, through the second crane arm being arranged such that it reaches into the practical working area, the timber-receiving unit to receive and carry in a retaining manner timber directly from the working area of the harvester unit and, independently of the movement of the harvester unit, carry out by the second crane arm the displacement of timber, which is transferred from the harvester unit within the practical working area, to a position in and above the load compartment.
