  • Patent number: 11536007
    Abstract: A system for proactively controlling rimpull limit of a machine includes a hydraulic system having a lift cylinder to move an implement; a lift cylinder pressure sensor that senses a hydraulic pressure of the lift cylinder and responsively produces a lift cylinder pressure signal; and a controller in operable communication with the power train and the lift cylinder pressure sensor. The controller is configured to receive the lift cylinder pressure signal; determine the rimpull limit based at least in part upon the lift cylinder pressure signal; and adjust the torque of the power train to the rimpull limit.

  • Publication number: 20080234901
    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.

  • Publication number: 20080206034
    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.

  • Patent number: 6135175
    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.

  • Patent number: 5176485
    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.

  • Patent number: 4715771
    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.

  • Patent number: 4565486
    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.

  • Patent number: 4343515
    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.
