  • Support Arm for a Work Machine
    Publication number: 20090223093
    Abstract: A support arm for a work machine is to be created whose design follows the component stresses to be expected to a high degree, which has the lowest possible intrinsic mass, and which can be manufactured with a minimum of effort. This is accomplished in that the support arm consists of at least one wall that has at least one plate-shaped element, which has at least one planar cut-out adapted to the component stresses expected, whereby at least one cut-out is closed off by a thin-walled cover element opposite the plate-shaped element.
