  • Patent number: 4315652
    Abstract: A grapple skidder vehicle has a grapple assembly rotatably and pivotally mounted with respect to an outer boom point end portion of a boom extending from the vehicle. The grapple assembly is supported from a cylindrical rotator shaft which is mounted for rotation in a bushed bearing which extends integrally upwardly from a base plate which forms a part of the boom point portion of the boom. The vertical thrust of the weight and load on the grapple assembly is transmitted through the rotator shaft to a rotator shaft operator arm concentric with and encircling the bushed bearing and to a relatively soft wear plate situated between the base plate and a bottom disc-shape base portion of the rotator shaft operator arm. The grapple assembly is pivoted with respect to the boom by a linear hydraulic motor pivotally connected between an outer end portion of the rotator shaft operator arm and the boom.

  • Patent number: 4129223
    Abstract: A bundle carrier attachment for a fork lift truck has a longitudinally extending, rectangular horizontal upper framework which is supported on longitudinally extending parallel tines of the fork lift truck. A pair of vertical support legs extend downwardly, one from each end of one longitudinal edge of the horizontal framework, and a bundle carrier tine is rotatably mounted with respect to each of these vertical load support legs in vertically spaced relation generally below one of the fork lift truck tines. These bundle carrier tines are integral with rotatable bundle tine support shafts which extend up inside of vertical support legs to and through the upper horizontal framework of the attachment.
