  • Pulling or lifting apparatus with jaws, acting on flat-profiled flexible straps
    Patent number: 5655754
    Abstract: A pulling or lifting apparatus for a flat, flexible strap connected to a load operates with two pairs of reciprocating jaws. The pairs of jaws have flat gripping surfaces corresponding to the flat faces of the flexible flat-profiled strap. Two guide members are disposed along each of the two broad faces of the strap and follow its longitudinal direction in order to prevent the strap from moving to form a fold or loop between the two pairs of jaws when these approach one another.
