A vehicle (2) comprising a working equipment (4) equipped with a movable loading arrangement (5) comprising a first attachment member (7), said vehicle further comprises a sensor system (6) configured to capture environmental data reflecting the environment around the vehicle and to determine, based on said data, image data (8) representing an area at least partly surrounding the vehicle (2). The sensor system (6) is configured to detect and track positions of the first attachment member (7) and a mating second attachment member (9) of the object (20) to load in said image data representation, and, the detected and tracked positions of the first and second attachment members (7, 9) are used to generate a first set of operation instructions for the loading arrangement (5) of the working equipment that decreases the distance between said first and second attachment members such that said attachment members (7, 9) come into position to engage to each other. The control unit 16 is configured to verify that said attachment members (7, 9) are engaged based on the detected and tracked positions from the sensor system (6), and in response to verifying that said attachment members (7, 9) are engaged, enable activation of an object loading mode in which the control system generates a second set of operation instructions for the working equipment to move the loading arrangement (5) so that the object to load is loaded on the vehicle.

A trailer adapted to haul one or more reels for carrying conveyor belts is disclosed. The trailer includes a loading means to lift the reel on the deck of the trailer. The loading means includes two articulated arms located each side of the trailer, each articulated arm comprising a first elongate member and a second elongate member pivotally mounted to the first elongate member. The first elongate members are movable relative to the trailer between a retracted position and a rearwardly extended position. The second elongate members are pivotable between a horizontal position and an upright position wherein the second elongate members are orthogonal to the first elongate members. A hoist is disposed between the second elongate members and is operable to lift the reel from the support surface to an effective height greater than an effective height of the deck. Jacks are also provided to stabilise the loading means.

A mobile working machine comprising: a chassis (5); stabilizer legs (10) connected to the chassis; a hydraulic crane (20) carried by the chassis and comprising a crane boom (25) articulately connected to a rotatable column (22) and a lifting cylinder (26) for pivoting this crane boom; and an electronic control device configured to establish a maximum allowed working pressure for the lifting cylinder while taking into account the contribution to the stability of the mobile working machine against tipping from each stabilizer leg (10) that is in an active supporting position. The electronic control device prevents a manoeuvring of a stabilizer leg away from the active supporting position if the working pressure of the lifting cylinder is higher than a threshold value corresponding to the value of the maximum allowed working pressure for the lifting cylinder that would ensue in case the stabilizer leg is made to leave the active supporting position.

This invention relates to off-road work machines and to unloading an off-road work machine and particularly to an arrangement and a method for controlling the unloading of a forestry machine. It is characteristic of a method according to the invention for controlling unloading of a forestry machine (10), in which the forestry machine (10) comprises a load space (11) for a timber load (22), a boom structure (12) and a wood-handling tool (16) attached to said boom structure, that the method comprises the steps of: defining and noting down (43), (44) the location (20) of the timber pile, calculating and noting down the location of the edge of the timber pile, picking (45) a timber bundle from the timber load (22) by the wood-handling tool (16), calculating (46) the distance of the end justified on a load screen (13) of the edge of said timber bundle from the wood-handling tool (16), calculating an unloading location for said timber bundle in the defined location (20) of the timber pile, and controlling and unloading (47) said timber bundle into the timber pile in the said calculated unloading location such that one edge of the timber pile becomes even and straight.

A crane arranged to be mounted to a vehicle and including a crane controller. The crane controller includes a machine learning algorithm, including a neural network trained to calculate a movements of a crane components based on a received trajectory instruction. A supervisory controller is provided arranged to evaluate the calculated movements by comparing an accuracy measure to a predefined safety margin. The accuracy measure is defined by the difference between a crane tip position resulting from the calculated movements when moved from a current position, and a position of the crane tip calculated by the supervisory controller, based on the received trajectory instruction and on positions of individual joints of said crane boom system, when moved from the current position, and to generate an overruling operating instruction for a system of actuators, in response to the accuracy measure being larger than the predefined safety margin.

A forestry machine includes a ground propulsion apparatus, a chassis supported by the ground propulsion apparatus, a cab, an engine and a work implement. The chassis includes a front chassis portion and a rear chassis portion. The front chassis portion includes an upper portion and a lower portion. The rear chassis portion has a wood basket supported thereon. The cab is rotatably supported on the front chassis portion by a rotatable connection about a cab rotation axis to be selectively rotated 360 degrees. The engine is integrated into the front chassis portion. At least a part of the engine is disposed below an upper most surface of the upper portion. The work implement is movably attached to the cab. The work implement includes a boom movably attached to the cab, an arm movably attached to the boom, and a work tool attached to the arm.
