  • Patent number: 9309098
    Abstract: A pallet fork includes a structural frame, a fork bar, a swing bar, and a pair of fork tines. The fork tines can be fixed or swinging through the removal of the swing bar. The swing bar can be conveniently stored onboard the pallet fork when it is inoperative. The structural frame is arranged for enhanced visibility by an operator to the fork tines to improve productivity and operator comfort.

  • Patent number: 8591145
    Abstract: A screed has an extendible frame portion that includes a catch engaging surface of an extension mounting system. The extendible frame portion is expandable along a lateral extension axis and pivotable about a pivot axis perpendicular to the lateral extension axis. A screed extension has a screed extension frame supporting a mounting catch of the extension mounting system. In a mounting configuration, the extendible frame portion is pivoted to a lowered mounting position, and the extendible frame portion is axially expanded to an extended mounting position in which the catch engaging surface and the mounting catch are vertically aligned. In a lifted configuration, the extendible frame portion is pivoted to a raised lifting position, the catch engaging surface and the mounting catch are in mating engagement, and the screed extension is supported on the extendible frame portion using the extension mounting system.

  • Patent number: 7882898
    Abstract: A quick coupler includes mounting structure for mounting the coupler to a machine, and for mounting the coupler to an implement. The mounting structure on the coupler includes wedge coupling surfaces and a tube. The mounting structure on the implement includes hooks for engaging the tube, and complementary wedge coupling surfaces. The wedge coupling surfaces wedge together during coupling to produce and tight fit and solid hold between the coupler and implement. The mounting structure is robust, and can accommodate future possible wear. The kinematic impact on the performance of the implement due to the use of the quick coupler is minimized.

  • Patent number: 5392864
    Abstract: Blade assemblies for use with compacting vehicles are normally designed to push the material in front of the blade and to control the height of the material passing thereunder for compaction by the compacting vehicle. With the blade raised to allow trash and/or soil to pass thereunder, the trash and/or soil passing thereunder may cause detrimental wear to the components under the compacting vehicle between the compacting mechanisms. In the subject arrangement, a blade assembly is provided and includes a blade pivotally connected to a frame. The blade has a working edge that permits, during use, level spreading of trash and/or soil when the blade is in a first operative position. When the blade assembly is raised and the blade is pivoted forwardly with respect to the frame, a first portion of the working edge controls the volume of trash and/or soil allowed to pass under the working edge between respective compacting mechanisms of a compacting vehicle.
