ABSTRACT:
An elevator lift system in which at least two connected hydraulic piston cylinder devices for controlling the vertical displacement of the lift platform above a lower level. One hydraulic cylinder includes a case connected to a second case and a piston slidably mounted within each case and movable in opposite directions. One of the hydraulic cylinders has a lift platform attached to its top end and the other hydraulic cylinder has its bottom end fixed to a base plate at a lower level. The hydraulic cylinders are connected to each other by the use of a housing which also encloses a control system which allows the rate of ascent or descent of both hydraulic cylinders to be equal. Multiple pairs of hydraulic cylinders are connectable to each other by way of a frame to reach additional heights and still allow the system to be lowered that the tops of all the cylinders are substantially flush. The frame includes another control system which allows the rate of ascent or descent of hydraulic cylinders of the pairs to be equal.
