Abstract: The invention relates to a system and method for changing liners of a mill, the configuration of which allows the automated robotic manipulation of liners of mills for ore grinding in comminution processes. The configuration and operation of the system allows the task of manipulation to be improved, having a greater degree of freedom and/or flexibility in its movements, thereby providing a greater degree of certainty and efficiency to the method and thus optimising the time that the mill is halted for maintenance, and also preventing the risks to which maintenance staff may be exposed. The system comprises at least one support structure, at least one system for supplying and moving liners, at least one robotic manipulator system for manipulating the liners, at least one liner manipulation tool, at least one artificial vision system, and at least one control system.

Abstract: A robot gripper for grasping, transporting, and depositing goods in transit including a gripper base having a coupling device for attachment to a robot arm, a carrying device extending in the longitudinal direction of the gripper and having a carrying surface which carries the object in transit and extends substantially in the longitudinal and transverse directions of the gripper, and a displacement device disposed above the carrying device and serving to apply force to the object in transit in the longitudinal direction. The carrying device and the displacement device are capable of being moved relative to each other in the longitudinal direction. A holding device is provided on the displacement device, by means of which holding device a holding force can be generated in order to prevent an object in transit resting against the holding device from losing contact therewith.

Abstract: A method and system for controlling a vehicle comprises a torque detector for detecting a first torque level and a second torque level applied to at least one wheel of the vehicle. The first torque level is associated with a lower boom position of a boom and a second torque level is associated with an elevated boom position higher than the lower boom position. A first hydraulic cylinder is capable of raising a boom from the lower boom position to raise an available torque from the first torque level. A second hydraulic cylinder is adapted to upwardly rotate or curl a bucket associated with the vehicle when the detected second torque level meets or exceeds a second torque threshold, for example.

Abstract: A mobile computer structure having a rotatable screen is provided, which includes a main body, a rotating arm, and a panel. The rotating arm is pivotally disposed on the main body and is pivotally rotated between a first position and a second position. The panel has a display surface and a casing surface and is pivotally connected to the rotating arm. When the rotating arm pivotally rotates to the first position, the panel is attached to the main body with the display surface facing the main body, and when the rotating arm pivotally rotates to the second position, the panel is attached to the main body with the casing surface, thus making the display surface or the casing surface optionally face outside to achieve the purpose of protection or using.

Abstract: A tree harvester provided with a rotatable worktable assembly is disclosed herein. The tree harvester includes a movable frame, a worktable assembly rotatably mounted to the movable frame and an upper frame rotatably mounted to the worktable assembly. The upper frame is provided with an articulated boom that includes a feller/grapple head. The worktable assembly includes a tree delimbing mechanism, a tree cutting mechanism and a log stacker. The operation of the worktable is advantageously automated so that the operator can use the boom while the worktable is processing a tree. The position of the worktable between the movable frame and the upper frame makes the tree harvester more compact than conventional tree harvester, while the independent rotation of the worktable assembly and of the upper frame with respect to the movable frame increases the flexibility of operation of the tree harvester.

Abstract: A freight manipulator includes a mobile chassis positioned on a pair of guide tracks and have an articulated cantilever boom extending forwardly thereof. A tool carriage is mounted at the end of the boom and has a pair of freight engaging tools thereon for engaging freight articles. The boom is connected to a two-axis gimbals at the rear of the chassis which allows swinging of the boom about a vertical axis and tilting of the boom about a horizontal tilt axis to increase the positioning range of the freight engaging tools. A boom bearing assembly at the front of the chassis supports the boom on the chassis during movement thereof. A pair of swing cylinders are connected to the chassis and have a chain connecting the ends of their rams to the bearing assembly. The swing cylinders work in opposition to swing the boom. A pair of boom tilt cylinders are connected between the bearing assembly and the boom and operate in unison to tilt the boom.

Abstract: An apparatus determining relative positions of arm elements of a manipulator having at least two relatively moveable arm segments uses image analysis and a model of the manipulator to analyze an image of the two arms to determine the joint angles between adjacent arms.

Abstract: A variable geometry mounting arrangement for the boom assembly of a backhoe is disclosed which permits relatively great working depths without increasing the overall height of the backhoe assembly in its raised, transport position. The arrangement includes a bellcrank coupler assembly operatively interposed between a swing tower and boom assembly of a backhoe, with a gearing arrangement provided operatively connecting the boom and the swing tower. By this construction, the vertical disposition of the horizontal pivot axis of the boom is altered as the boom is pivoted. The bellcrank coupler asembly provides a central anchor for the hydraulic fluid boom actuator of the backhoe, and permits the actuator to work through a relatively large moment arm for enhanced performance, and further permits use of a relatively simpified box-section boom construction.

Abstract: A device for handling material is shown according to the teachings of the present invention in its preferred form as a mobile tree felling and handling device. In its preferred form, the device includes a mid-frame pivotally mounted to the device frame about a pivot axis which is perpendicular to the longitudinal axis of the device. The mid-frame is pivoted about the mid-frame axis in the preferred embodiment by first and second hydraulic rams which extend from the back of the mid-frame to the device frame. Further, the device in the preferred embodiment also includes a turntable pivotally mounted to the mid-frame about an axis which is generally parallel to the longitudinal axis of the device and which is generally midway between the sides of the mid-frame. The turntable is pivoted about the axis between the turntable and the mid-frame by trunion mounted cylinders mounted on opposite sides of the pivot axis which allow a very compact design while allowing a high degree of tilt.

Abstract: The invention relates to a device for rotating a body, such as the boom of a roadheader. The device comprises a pivotally mounted yoke having in it a slot in which is slidably mounted a member which is rotatably and eccentrically attached to the body, and a pair of opposed pivotally mounted rams each of which is rotatably attached to the yoke, the rams being operated out of phase such that they cause the yoke to pivot about its mounting, the pivotal movement being translated into a rotation of the body by movement of the member in the slot. Preferably the member is moved to and fro in the slot by means of a third ram mounted on the yoke.
