ELASTIC LOAD SUSPENSION Russian patent published in 2008 - IPC B66C1/34 

FIELD: mechanical engineering; load lifting machinery.

SUBSTANCE: proposed suspension contains hollow cylindrical housing, elastic member, return spring and rod with load-gripping member getting out of limits of housing. elastic member is made in form of elastic cylindrical shells installed concentrically without contact, and pliable transfer link is placed in clearance between shells. Ends faces of shells are trimmed with elastic cover plate against which end face supports rest being aligned by ring projection in clearance between shells.
