  • Conductive shoe assembly for trolley or the like
    Patent number: 4221282
    Abstract: An assembly for attaching a conductive shoe to a trolley or like vehicle, wherein a pair of elastic rods function to bias the conductive shoe into gliding, electrical contact with a conducting rail in spite of changing distances therebetween, with the elastic rods also providing electrical insulation between the conductive shoe and the trolley, effectively reducing the overall weight of the shoe.

  • Travelling cable support system
    Patent number: 4093047
    Abstract: A travelling cable support system for cranes, in which a cable is fixedly secured between successive sleds, is discussed. The sleds are connected together by resilient tension elements which stretch elastically on acceleration and subsequently give up their stored potential energy as kinetic energy. Non-elastic traction cords are also provided in conjunction with the cable and elastic elements for limiting the extension of the elastic elements.
