An arborist block is provided that includes a front plate having a front plate inner surface, a back plate having a back plate inner surface, a sheave rotatably coupled to a sheave axle secured between the front plate and back plate and radially centered along a sheave rotational axis, and a plurality of sheave locks situated in sheave lock tracks and radially extendable into a plurality of lock receiving recesses in the sheave to prevent rotation of the sheave relative to the sheave axle.

A brush management system that includes a feller-buncher-cutter for cutting brush and moving cut material, and a chipper for receiving the b's rush material.

The invention relates to a marking device (10) for applying a marking on an object. The marking device comprises a striking arm (11), which is provided with a striking head (12) at its outer free end, and actuating means (30) for actuating the striking arm (11). The striking arm is movably connected to a base (7) through a link arrangement (30). The striking arm is pivotable about a pivot axis (V1) under the effect of the actuating means and the link arrangement from a resting position to a striking position so as to thereby allow the striking head to hit against an object in order to apply a marking on the object. The link arrangement is arranged to move the pivot axis of the striking arm outwards so that the distance between this pivot axis and the base increases when the striking arm is pivoted from the resting position to the striking position.

An arrangement and method for measuring a piece of timber in a wood handling machine, wherein the piece is grabbed by a cutting head arranged to a set of booms in the wood handling machine, and the dimensions of the piece are measured by at least one measuring device in the wood handling machine. A measuring signal field formed by one or more measuring beams is also directed to the piece of timber with a monitoring device utilizing contact-free measurement, and a point cloud to be stored is provided by the measuring signal field it produces. The parts to be identified are identified from this point cloud, and a quantity to be measured is defined and formed of the information content of the point cloud. The obtained result is directed to a measuring system in the wood handling machine for further utilization.

A log marking device (1) comprising a log marking tool (2) with a striking head (10) provided with adjustable marking members, and a setting unit (3) with setting members for setting the marking members in desired positions or states. The setting unit also comprises: a housing (30) with a seat (31) for receiving the striking head; actuators for controlling the movements of the setting members; andan electronic control unit for controlling the actuators. The striking head (10) is moveable into a setting position, in which the striking head is received in the seat (31) of the setting unit with each marking member in contact with the associated setting member so as to allow the setting unit (3) to set the positions or states of the marking members by operation of the actuators.

A method and system for timber harvesting and supply chain management are disclosed, focusing on supporting forestry and timber harvesting productivity and utilization monitoring the timber harvesting supply chain. The method involves obtaining performance data from timber handling machines and determining the volume of timber processed by analyzing machine paths, work operations, and the working area, coupled with regional timber volume data. The system generates worklogs, providing useful insights into timber handling activities, which can be used to direct further timber harvesting actions. The present invention offers improvements over existing methods by offering a tool for data driven decision-making, thus optimizing operational workflows and resource management.

The invention relates to a method for felling sawing using a forest machine. In the method, a felling head is used, which set near to the tree to be felled. In addition, sawing is performed on the tree using a saw device fitted to the felling head. Before sawing, the saw device is set to a selected level relative to the ground surface, which is recorded in the data system belonging to the forest machine. The invention also relates to a system for felling sawing using a forest machine.
