Abstract
A lift systemmay comprise two sets of two pistons with each set of pistons attached to an upper cross barand a lower cross barwith the lower cross bar having distal ends comprising distal insertion areaswith the distal insertion areas passing through a first voiddefined within a wheelie barand the distal insertion areasreaching further to move a wedge barTo lift a patient from a lowered position, a piston moves a lower cross barwhich in turn moves a wedge barinto a wedgecausing the lower cross bar to break out of plane with a top barThe use of two wheelie gearsensures that the lift remains horizontal even if piston forces are not uniform.
