  • Patent number: 4035010
    Abstract: The present invention discloses a device for gripping and lifting large-sized T-shaped structural members (to be referred to as the "T structural member" for brevity in this specification) each consisting of a face plate and a web plate. The T structural member gripping and lifting device comprises a beam adapted to be suspended from a crane or the like, a plurality of trolleys movably mounted on the beam and remotely controlled so as to adjust the spacing therebetween, a gripping unit suspended from each trolley and remotely controllable so as to grip or release the face plate of a T structural member, and a remote control unit for controlling the trolleys and the gripping units whereby the T structural member may be automatically gripped, lifted and released. Handling efficiency may be considerably increased to such an extent hitherto unattainable by any conventional devices, and the safeguarded operations may be ensured.
