  • the ihvshfim is Partisulsrly characterized by a timber supporting frame surround- 6 ing the pruning device and mounted on the chassis.
  • FIG. 1 A first figure.
  • the present invention concerns a timber handling machine, consisting of a fetching jib tumable in the vertical and horizontal planes and mounted on a tractor or other transporting chassis, which jib has a grasping element for grabbing the felled tree, and furthermore of a pruning device provided with timber handling equipment, tumable in the vertical and horizontal planes and mounted on the transporting chassis.
  • Many types of timber handling machines of this kind are previously known, but they all have the circumstance in common that the elements performing various work phases have been dependent on each others operation. As a result, delays have been caused by the transfer of the piece of timber from one treatment phase to the other. In other words, the machine has not been able to operate at full capacity. Especially the handling of small trees has become expensive, per unit cubic volume of wood, with existing machines.
  • the aim of the present invention is to afford a timbe handling machine which eliminates the drawbacks mentioned above.
  • This invention is mainly characterized in that on the chassis belonging to the machine, on which the pruning unit provided with timber handling equipment has been mounted, there is, surrounding the said unit, a supporting frame or equivalent for the timber, upon which frame or equivalent the fetching jib may deposit a piece of timber which it has fetched from any direction, and from which the pruning unit may grab the piece of timber.
  • a timber handling machine has been provided with a timber supporting frame, upon which the fetching jib may at any time deposit the piece of timber which it has fetched and from which the pruning unit may, after having pruned the preceding tree, pick up another tree, the operation of the fetching jib is not restricted by the operation of the pruning unit. It is advantageous if the timber supporting frame consists of a ring-shaped support attached to the chassis by the aid The invention is described in greater detail in the following with reference to the embodiment shown in the attached drawings.
  • FIG. 1 shows a timber handling machine according to the invention, seen from above, and
  • FIG. 2 shows the same device in elevational view.
  • the timber handling device shown in the drawing comprises a movable chassis l, which may be a forestry tractor or any equivalent vehicle able to negotiate roadless terrain.
  • a fetching jib 2 which is tumable in the vertical and horizontal planes and can be shortened and 5 lengthened, and which belongs to prior art.
  • the timber supporting elements may be displaceable. It is advantageous if the timber supporting frame provided with timber suping it consists of an articulated jib, but it may also be of the telescopic type.
  • a grasping element 3 To the end of the fetching jib there has been articulatedly attached a grasping element 3, in itself belonging to prior art. It can be used to grab a tree that has been felled and to transport it into desired location.
  • the body 4 On the said chassis 1 there has been mounted the body 4, tumable about its vertical axis, of a pruning unit provided with timber handling equipment. To the body 4, the sleeve-like frame 5 has been articulatedly attached.
  • a ring-shaped support 12 encircling it on three sides, in such manner that is is located higher than the platform and outside it, in order that the pruning device may readily grab any the resting on the supporting frame.
  • the ring-shaped support 12 has been provided with timber support elements 13, which are positioned to lie on each others continuation and which have an M-shaped cross-section. Accordingly, there are formed in the timber supporting device V- shaped chutes l4 and 15, which are intended for one piece of timber each.
  • the pruning device may be furnished with automatics so that there is a selection station for each timber supporting element, whereby depressing the push-button of any desired selection station causes the pruning unit automatically to turn into proper position and to grab the tree with its grasping element.
  • the timber supporting frame may also be provided with timber support elements in such manner that the support elements are displaceable and can be locked in desired positions. It is also possible for the supporting elements to have chutes of other V shape.
  • the timber support elements may also be provided with small spikes, which prevent the timbers from falling down if it is necessary to move the timber handling machine over a short distance. It
