A device for securing logs from harvested timber to a transport vehicle, or logging truck, using log wrappers. The log wrapper securement device can be located in the inspection cavity of a forestry grapple. The forestry grapple is attached to a log loader. The log wrapper securement device includes a base plate sized and shaped to replace the inspection plate covering the inspection cavity. The base plate includes a slot sized and shaped to receive a portion of a chain end link or other chain links of the log wrapper, which can be inserted manually. The loader operator can remotely control the actuator to secure the chain link and release it, once the log wrapper is positioned over the other side of the logging truck. The log wrapper securement device can potentially reduce injuries and save lives.

Provided is a holding apparatus capable of holding a holding object with sufficient holding force from either of the outside and the inside. The holding apparatus includes a holding-apparatus body, a first and second arms, an opening and closing mechanism, a driving device, and a first and second holding elements. The opening and closing mechanism interconnects each of the first and second arms and the holding apparatus main bodies so as to allow the first and second arms to be moved in the opening and closing direction while kept in the holding posture. The first and second holding elements is pivotably connected to the arm lower region, having respective inner contact surfaces opposed to each other in the opening and closing direction and respective outer contact surfaces facing the opposite side.

The invention relates to an agricultural device for semi-automatic movement of a holding tool, for holding an object, between two positions, said two positions being at different heights. The device comprises said holding tool for holding the object, load sensing means for determining if the holding tool holds an object, driving means (9) for moving the holding tool up and down, a control unit for controlling the driving means, and a user interface for user input to the control unit. The device can be used in two modes of operations, wherein the holding tool in a first mode of operation is freely movably, and in a second mode of operation is semi-automatically movable between a plurality of determined positions (URP, UPP, LRP, LPP) depending on if the holding tool is holding an object or not, and which command is given to the user interface. The invention further relates to an agricultural vehicle comprising such an agricultural device, a method for an agricultural device, for such semi-automatic movement, and software for obtaining information related to driving means, said software being adapted to perform the method according to the invention.

A holding device for use with a telescopically extensible crane boom (57) in order to keep a load handling tool (4) in a given parking position in relation to the crane boom. The holding device (1) comprises: an attachment (10) to be fixed to an end of a telescopic crane boom section of the crane boom; a tool holder (15), which is detachably mountable to the attachment (10) and configured for engagement with the tool in order to support it against the crane boom and keep it in the parking position, the tool holder being provided with a sliding member (28), through which the tool holder is configured to slidably rest against an external surface on the crane boom; and a locking mechanism (16) for locking the tool holder and the attachment to each other when the tool holder is mounted to the attachment.

The invention relates to a linking device for coupling working equipment, such as a head for harvesting trees, to the end of a crane boom on a working machine, said end comprising crane ears, wherein the linking device comprises a linking device body that supports a first rotation shaft defining a first rotation axis and a second rotation shaft defining a second rotation axis that runs substantially transverse to the first rotation axis, wherein the linking device is intended to be suspended by the first rotation shaft between the crane ears for free rotation of the linking device around the first rotation axis on the crane boom, wherein the linking device comprises first braking means for braking the rotational movement of the linking device around the first rotation axis, wherein the first braking means are arranged to move at least one of the crane ears towards the other to clamp the linking device body between the crane ears.

A crawler type crane having a base carrier unit having a control unit associated therewith and an upper portion assembly having a boom portion coupled at end to the base carrier unit and to a jib portion at an opposed end. The boom portion includes one or more selected boom sections that are articulatable relative to each other. The crane also includes a multi-function attachment unit that is coupled to the jib portion and has a grappling unit for grasping a work piece and a saw attachment unit for cutting the workpiece. The crane can also include a first fluid regulating device coupled to the jib portion for regulating a fluid to the jib portion and to the multi-function attachment unit and a second fluid regulating device coupled to the boom portion for regulating a fluid to the winch element and to the multi-function attachment unit.

The invention concerns an arrangement for the guidance of flexible lines that run from a crane arm (3) through its end section (2) to a tool (4), that is suspended at the crane arm through a link arrangement (5) and a frame that is a component of a rotator (6) for rotation around a vertical first axis (A) and in a cardan manner around second (B) and third (C) horizontal axes, For the discrete and protected passage of hoses, it comprises a first holder (35) in an opening (3A) of the end section (2), a second holder (38) in a central region of the rotator (6), a first hose package (1A-1D) that extends between the said first (35) and second holders (38), a penetration (26) in a central region of the rotator (6) and permitting hydraulic fluid to pass through the rotator (6) and onwards to a lower part (18) of the same at least one of the said second (B) and third (C) horizontal axes comprises an “open joint”.
