  • Linkage assembly restraint
    Patent number: 7056079
    Abstract: Work machines having linkages may need to have the linkage assembly locked in a predetermined position to prevent damage to an implement attached to the work machine, to prevent tipping of the work machine, to operate the implement, or other reasons. Locking the linkage assembly, however, can create significant loads on the linkage assembly. The disclosed method and apparatus is for a work machine that comprises a chassis, at least one linkage assembly attached to the work machine, at least one restraint having a first-end portion and a second-end portion, the second-end portion being attached to the chassis and the first-end portion being attached to the linkage assembly, the restraint transferring a load from the linkage assembly to the chassis.
