  • Hydraulic elevator system
    Patent number: 8640829
    Abstract: The hydraulic elevator system has several configurations, each incorporating the hydraulic motor and pump at the lower end of the hydraulic ram and cylinder assembly. A first embodiment utilizes a wet pump and motor assembly at the lower end of the cylinder, with the volume between the cylinder and casing providing a hydraulic reservoir. A second embodiment provides a dry pump and motor installed at the lower end of the cylinder below the surrounding casing and hydraulic reservoir. A third embodiment attaches the pump and motor to the lower end of the hydraulic ram, with the pump and motor traveling up and down with the ram during operation. Further systems facilitating the installation and removal of the hydraulic cylinder and attached components for maintenance are also provided.
