Machine roomless hydraulic elevator system

摘要

A hydraulic elevator system does not include a machine room but does include an access panel that allows at least a control valve and controller to be accessible from outside of the hoistway while the control valve and controller remain in the hoistway. An exemplary elevator system includes a hoistway. An elevator car is supported within the hoistway. The hydraulic cylinder is associated with the elevator car for selectively moving the elevator car. A reservoir is within the hoistway. The reservoir is configured to contain fluid for selectively causing extension of the cylinder. A control valve within the hoistway controls communication of the fluid between the reservoir and the cylinder. A controller within the hoistway controls movement of the elevator car. An access panel is on one side of the hoistway for selectively closing and opening into the hoistway near the control value and the controller. The opening provides access to at least the control valve and the controller from outside of the hoistway.

1. An elevator system, comprising:
a hoistway; an elevator car supported within the hoistway; a hydraulic cylinder associated with the elevator car for selectively moving the elevator car; a reservoir within the hoistway, the reservoir being configured to contain fluid for selectively causing extension of the cylinder; a control valve within the hoistway, the control valve controlling communication of the fluid between the reservoir and the cylinder; a controller within the hoistway for controlling movement of the elevator car; an access panel on one side of the hoistway for selectively closing an opening into the hoistway near the control valve and the controller, the opening providing access to at least the control valve and the controller from outside of the hoistway wherein the control valve and controller remain in the hoistway while being accessed through the access panel.
