Abstract: An elevator car speed governor is mounted on the top of the car assembly, and measures car speed by contacting a fixed element in the hoistway. The fixed element can be a taut cable extending from the top of the hoistway to the pit, or one of the car guide rails, for example. The governor has a centrifugally operated connection with emergency brakes on the car. When overspeed is detected, the connection is actuated to cause the brakes to engage the guide rails and stop the car. The governor can operate at relatively low overspeed rates, and can be used on elevator systems which do not have an overhead machine room, such as hydraulic and linear induction motor elevators.

Abstract: An hydraulic elevator (10) is powered by a pair of jacks (45) disposed adjacent to opposite sides of the platform (40) of the elevator car at medial locations thereon for enhanced compactness of the elevator and generally symmetric, nonbending support of the car.

Abstract: An elevator cab is constructed of thin, somewhat semirigid skeleton. Panels, made of expanded core plastic, or honeycomb paper, are attached to the skeleton, thereby forming a very light and rigid cab. These panels are attached by means of releasable hook-like fasteners, thus permitting selective removal of the panels from the skeleton. Due to strategic location of the fasteners on the skeleton, the panels, when attached to the skeleton, create a rigid cab.
