Abstract
Disclosed is an improved hydraulic lift system comprising a cylinder housing preferably in the shape of a regular polygon which applies compressive force to a cylinder within the cylinder housing. This cylinder is preferably made from extruded plastic. Within the cylinder is a three ringed piston to which is attached a piston rod. The piston rod is adapted for connection to a horizontal cantilevered arm assembly. The improved lift permits cantilevered transport from specially designed handicapped chairs and stretchers for access to and egress from a pool or spa.
