  • Electro-hydraulic auxiliary mode control
    Patent number: 8621855
    Abstract: A work machine (10) comprises an auxiliary electro-hydraulic circuit (22) adapted to operate a hydraulic actuator (16) of an auxiliary tool (12) when the auxiliary tool (12) is attached to the work machine. The auxiliary electro-hydraulic circuit (22) is electrically controlled by a controller unit (24) in a proportional mode or a continuous mode.

  • Apparatus for Grinding Workpieces
    Publication number: 20090093197
    Abstract: An apparatus for grinding a planar work piece which is conveyed along a transport path defined by at least partly driven supporting rollers and pressure rollers, contains a revolving grinding element which extends into the transport path and which contacts the work piece circumferentially on its way along the transport path. A pressure device is provided which applies an elastic pressure force to the revolving grinding element in the direction of the work piece in such a way that the revolving grinding element is set flexibly against the planar work piece in such a way as to follow the contour of the latter.

  • Multiple mode operational system for work vehicle braking
    Publication number: 20060095186
    Abstract: A work vehicle includes a multiple mode operational system having a work system such as a linkage and associated hydraulic cylinders of a backhoe, a braking system and a multiple mode control system. The multiple mode control system includes a central controller, a mode toggle switch and a work system control device such as an electromechanical joystick. The central controller is capable of entering at least a first operational mode and a second operational mode. In the first operational mode, the central controller manipulates the work system based on signals received from the work system control device. In the second operational mode, the central controller controls the braking system based on signals received from the work system control device.
