  • Patent number: 4492402
    Abstract: A special purpose grab adapted specifically for on-site employment in clamping and up-ending relatively narrow width reels of coiled strip material for the turning thereof from either an axis vertical-to-horizontal configuration, or visa versa.
    Type: Grant
    Filed: March 28, 1983
    Date of Patent: January 8, 1985
    Assignee: Bradley Lifting, Corp.
    Inventor: Harvey Bradley
  • Patent number: 4262952
    Abstract: A lifting tong link arm-to-tong arm toggle lock comprised of a rack and pinion sub-assembly member operably interposed to work angularly across one of the two symmetrical pivotally assembled scissor-acting upper link arm-to-lower tong arm junctures of a simple tong grab toggle structure, wherein the pinion wheel thereof is further provided with a ratchet wheel axially affixed thereto whereby the cooperatively activated release or engagement of a solenoid operated pawl with the ratchet tooth structure thereof respectively enables either opening of the tong for a grappling load engagement thereby or locking of the extended load suspending lifting tong structure when a load is grappled for movement thus providing a positive mechanical capability to prevent either an accidental or unintentional operator release of the load upon a load support surface after grapple displaced transport of a load from one location to another intermediate of and prior to accomplishing a final placement positioning deposit thereof.
    Type: Grant
    Filed: December 26, 1979
    Date of Patent: April 21, 1981
    Assignee: Bradley Lifting Corp.
    Inventor: Harvey Bradley
  • Patent number: 4253696
    Abstract: A motorized lever-action vertical axis coil grab manipulated in suspended disposition from an overhead crane by a single operator from a remote control location for clampably engaging for lifting and displacement from one location to another upright standing wrapped metal material coils of various size and dimension, with initial grab engagement of any particular coil to be moved by a motor-driven compressive clamping of the coil overply wall thickness to remove therefrom any wrap slack sponginess preparatory to tong latch release of the grab lever-acting self-gripping force translating tong linkage assembly such that no extension of the tong linkage assembly thereof will be wasted in taking up coil wrap slack but rather be substantially translated as increasing clamp compression on the coil wall thickness in a gripping force transmission sufficient to lift the coil without the convoluted laminate wrap structure thereof slipping apart upon coil elevation for movement, wherein the grab hereof further embodies
