Abstract
A hydraulic elevator system which utilizes a single hydraulic jack having a cylinder fixed below an elevator car, and a plunger. The elevator car is supported on the end of the plunger. The hydraulic jack extends upwardly and into the elevator car, reducing the space required below the car by the amount of the penetration of the hydraulic jack. The hydraulic jack is disposed adjacent to the front portion of the hatchway, enabling it to occupy an enclosed, concealed space in the elevator car, between its entranceway and its operational controls.
