The present invention relates to an articulated tracked vehicle comprising a front and a rear vehicle unit connected by means of a rigid load-carrying frame. The load-carrying frame is pivotally attached to the front vehicle unit about a substantially vertical front steering link and pivotally attached to the rear vehicle unit about a substantially vertical rear steering link. The vehicle further comprises control means arranged to steer the front vehicle unit relative to the load-carrying frame about the front vertical steering link and to steer the rear vehicle unit relative to the load-carrying frame about the rear vertical steering link, wherein the control means is arranged such that the front and rear vehicle units are individually steerable relative to the load-carrying frame about their respective vertical steering links.

A pressure compensated load sense hydraulic system and method is disclosed where a first pressure compensated valve controls flow between a pump and a first function based on a highest function load; and a second pressure compensated valve controls flow between the pump and a second function based on the highest function load. First and second operator controls activate the first and second functions, respectively. When the first function is stalled and the second function is activated, the controller closes the first valve to remove the first function load from the load sense circuit and prevent flow to or from the first function. The controller can determine the first function is stalled when a timer exceeds an initialization period. When the controller closes the first valve, it can cycle the first valve between a shutoff period where the valve is closed, and a refresh period where the valve is opened.

A load control device includes a camera to capture information of objects of load handled by a load handling device to forward such information to a computer, which compares load data derived therefrom with reference data in a data source and emits a signal to an output device in the case of a certain conflict between the data.

A grapple tip includes an outer volume having a working end with a rounded surface. The grapple tip may further include a mounting end, a right side, a left side, a bottom surface, and a top surface. The top surface features a grooved recess that may help the device pick up, hold on to, and transport heavy items such as lumber or construction implements across significant distances. In addition, the grapple tip may also have a raised projection extending from the mounting end to ensure a secure and correct mounting on a damaged grapple assembly claw. The grapple tip is useful for upgrading or replacing existing tips that may have become damaged or worn.

A folding assembly for an actuation lever is disclosed. The folding assembly includes a first shaft and a second shaft pivotally coupled to the first shaft. The second shaft includes a first engagement structure and a second engagement structure spaced apart from the first engagement structure. The folding assembly further includes a sleeve slidably disposed around the first shaft and the second shaft. The sleeve comprises a mating structure adapted to engage with the first engagement structure or the second engagement structure. The sleeve is adapted to cover a portion of the first shaft and a first portion of the second shaft, when the mating structure is engaged with the second engagement structure. Further, the sleeve is adapted to cover a second portion of the second shaft such that the sleeve releases the first shaft, when the mating structure is engaged with the first engagement structure.

A system (100) comprising a boom tip attachment bracket (108) on a boom (102) of a working machine, the boom (102) having an actuator (104) attached thereto and one or more flexible lines (106), a processing head attachment bracket (110) for rigidly attaching a processing head (112) to the boom (102) of the working machine, the processing head attachment bracket (110) having a line connection point (114) for connecting the one or more flexible lines (106), and an internal line passage (116) for passage of the one or more flexible lines (106) from the boom (102) to the line connection point (114). The boom tip attachment bracket comprises (108) a first rigid frame (118) having at least two plates (120a, 120b) spaced from each other by a first spacing distance (122) so as to comprise at least a portion of the internal line passage (116), and a pair of first coupling points (124a, 124b) opposed across the first spacing distance (122), for rotatably coupling the rigid frame (118) to the processing head (112) along a first rotation axis (126a). The processing head attachment bracket comprises a second rigid frame (128) having at least two plates (130a, 130b) spaced from each other by a second spacing distance (132) so as to comprise at least a portion of the internal line passage (116); and a pair of second coupling points (134a, 134b), opposed across the second spacing distance (132), and rotatably coupled with the pair of first coupling points (124a, 124b) along the first rotation axis (126a). The processing head attachment bracket (110) is coupled to the actuator (104) by a torque assembly (136) for translating actuation of the actuator (104) into a rotation of the processing head attachment bracket (110) about the first rotation axis (126a), and the internal line passage (116) passes through at least the first rotation axis (126a).

A crane with a crane control, wherein the crane control includes rises a coordinate control system with a plurality of nodes defined in the crane, a three-axis coordinate system including x, y and z axes that intersect each other in orthogonal main planes in the space, a node information processing module, a route establishment module and an operation processing module, wherein the node information processing module is configured to collect and store node information in an initial state of the crane, and the route establishment module is configured, based on a control command indicated by a crane operator, to establish an effective operation path for each node to a route in which the operation module is used, in an actual route, for displacing a crane tip included in the crane from a current starting or initial coordinate position in the initial state to a desired target coordinate position in the space.

A control system for moving an end effector of a work machine may include sensors for determining current orientations of components of a boom assembly connected to the work machine. A controller may be configured to receive, via an input interface, signals corresponding to a velocity input command for a desired movement of the end effector. The controller may determine, based upon the velocity input command and signals from the sensors, at least one target velocity for one or more actuators for the boom assembly. Commanding the actuators to move with the at least one target velocity may cause the end effector to move with an aggregate velocity corresponding to the desired movement of the end effector, as indicated by the velocity input command.

A method of and arrangement for monitoring the collection of plant material includes the following steps and apparatus for executing these steps, respectively: collecting plant location and attribute data with respect to plant material, before and/or during and/or after harvesting the plant material, providing the plant location and attribute data on a collecting vehicle adapted to collect the harvested plant material, moving the collecting vehicle to the harvested plant material based on the plant location data, collecting the harvested plant material, sensing attribute data of the harvested plant material before and/or during and/or after the collecting, and comparing the sensed attribute data with the plant attribute data and generating an output dependent on the result of the comparison.
