Disclosed is a system for managing identification information for a log. The system comprises an arrangement for determining an origin of the log, a computing device communicably coupled to the remote server arrangement and a communication interface that is operable to transmit the captured at least one subsequent image to the remote server arrangement. The arrangement for determining an origin of the log further comprises at least one imaging device coupled to a forest harvester, a Global Positioning System (GPS) receiver that is operatively coupled to the forest harvester and a data processor that is communicably coupled to a remote server arrangement and operable to process the captured at least one image and the determined felling location of the log to create the identification information for the log.

In the disclosed solution, a boom assembly (14) of a work machine (1) is controlled by tip control. In tip control, a control command is given to a tip of a boom assembly (14), converted into control commands for individual actuators of the boom assembly (14). In the disclosed solution, a variable related to a load and its position at the tip of the boom assembly (14) is defined, and the variable in question related to the load and its position at the tip of the boom assembly (14) is taken into account in the control command for the actuator.

A method for an operation of a forestry winch, which has a rope drum driven by a drive motor and on which a rope is wound up, and has a rope ejector roller for the rope driven by an additional drive motor, whereby the rope is guided from the rope drum to the rope ejector roller and is deflected on the rope ejector roller. The drive motor of the rope drum and the additional drive motor of the rope ejector roller are operated so that when the rope is unspooled from the rope drum, and when the rope is wound up onto the rope drum, a minimum rope pre-tension, in particular a constant minimum rope pre-tension, is generated in the segment of the rope between the rope drum and the rope ejector roller.

An apparatus for hoisting and forwarding of logs enables the forwarding of logs along an axis towards a processing area. The apparatus is adjustable in height either due to various configuration of ground or to various heights of processing area in various wood processing machines, and is comfortable both for each user as well as for manufacturers and distributors. The apparatus is also easy to transport to any desired locations by using a tractor. To this aim, supporting legs on the apparatus are telescopic and connected a bearing framework, with a movable part engaging the ground. Bearing members on a hoisting unit are telescopic and embedded in the bearing framework, with a displaceable part engaging the ground. The bearing framework may be provided on its side and faced away from the hoisting unit, as well as furnished with a coupling member for connecting the apparatus to a tractor.

The present invention relates to a system for remote and/or autonomous cutting at least a portion of a harvested ligno trunk, at least a portion of a ligno trunk to be harvested, at least a portion of a ligno trunk during harvesting or at least a portion of a ligno trunk during transporting, said system comprising: a remotely and/or autonomously controlled Unmanned Aerial Vehicle (100), UAV, means for cutting at least a portion of a ligno trunk attachable to said UAV, means for detecting at least a portion of a ligno, means for detecting at least one ligno parameter of at least a portion of a ligno and/or at least one growing condition of at least a portion of a ligno, a base station (120) for communication with said UAV, and means configured for selecting at least one cutting position on at least a portion of a ligno trunk depending on the at least one detected ligno parameter and/or the at least one detected growing condition of at least a portion of a ligno.

The invention relates to a system (10) for remote and/or autonomous transporting at least a portion of a tree, said system (10) comprising an unmanned aerial vehicle (100), UAV, comprising, at least one means (105) for holding said at least a portion of a tree, said system comprising at least one means for detecting said at least a portion of a tree to be transported, and means for detecting at least one of the group of tree parameters: diameter of a tree, length of a tree, tree species and/or the weight of a tree, a base station (120) for communication with said means configured for transporting said at least a portion of a tree and/or said UAV (100) and means configured for directing said remotely and/autonomously UAV (100) with said at least a portion of a tree to a final destination where said final destination is depending on said detected tree parameters.

An adapter method and system includes a first side deflector, a second side deflector, and a top deflector coupled to the first side deflector and the second side deflector. The system may further include an internal deflector coupled to the first, second, and top deflectors. A first leg is coupled to the first side deflector and a second leg is coupled to the second side deflector. The legs are adjustable between a first position and a second position. The first, second, and top deflector define an entrance region for channeling wood-based debris into the chute of a woodchipper. Each side deflector may include a coupling mechanism for attaching to a woodchipper. Each coupling mechanism has an aperture. Each leg may telescope within a respective side deflector.

A control system for controlling a tool of a machine includes at least one controller and detecting means. The detecting means includes at least one range finder device for at least partly detecting and positioning an object with regards to the tool in 3D space. An operation mode of the at least one controller depends at least in part on the object. A machine and a method for controlling a tool of the machine are also disclosed.

A condition of at least one structural part (11′, 11″) of a working machine (10) is determined by detecting (201) a force of a changing magnitude to a first structural part (11′) or a structural part connecting the first structural part (11′) to the second structural part (11″), determining (203) a change in the position of the first structural part with respect to the second structural part as a function of the force detected, and determining (205) the condition on the basis of the change in the position of the first structural part with respect to the second structural part as a function of the force detected. At least a slope of the change in the magnitude of the force is detected.
