						single buttons or switches, or both, in the car, and up-or-down direction
						buttons, or both, at the landings, by which predetermined landing stops may be
						set up or registered for an elevator or for a group of elevators. The stops set
						up by momentary actuation of the car buttons are made automatically in
						succession as the car reaches those landings, irrespective of its direction of
						travel or the sequence in which the buttons are actuated. The stops set up by
						the momentary actuation of the up-and-down buttons at the landing are made
						automatically by the first available car in the group approaching the landing
						in the corresponding direction, irrespective of the sequence in which the
						buttons are actuated. With this type of operation, the car can be started only

(B)
						Gurney Lift. A gurney lift is a hoisting and lowering mechanism, for use by a
						person(s) in a gurney, stretcher or similar device and an attendant(s) and
						possibly a support system. It consists of a platform with a minimal enclosure
						that moves through a fixed course either vertically or on an incline, and is
						used or fixed in a permanent location. The Division shall determine the
						specific lifts which are gurney lifts, for the purpose of these orders. This
						determination shall apply equally to all similar or identical lifts used in a
						similar manner.
(C) Platform
						(Wheelchair) Lift. A wheelchair lift is a hoisting and lowering mechanism for
						use by a person unable to use stairs. It consists of a platform with a minimal
						enclosure that moves through a fixed course either vertically or on an incline
						(which is often a stairway), and is used or fixed in a permanent location. The
						Division shall determine the specific lifts which are wheelchair lifts, for the
						purpose of these orders. This determination shall apply equally to all similar
						or identical lifts used in a similar or identical manner.
1. Inclined Platform (Wheelchair) Lift. An
						inclined wheelchair lift is a wheelchair lift designed to operate on an incline
						which is often a stairway.

						  device located at an elevator landing which when activated causes the elevator
						  car to stop at that floor.
Supply Piping. The piping for a hydraulic elevator
						  between the control valves and the driving member of the driving
						  machine.
Terminal Speed Limiting Device, Emergency. A device
						  which automatically reduces the speed as a car approaches a terminal landing,
						  independently of the functioning of the operating device, and the normal
						  terminal stopping device, if the latter fails to slow down the car as
						  intended.
Terminal Stopping Device, Emergency. A device which
						  automatically causes the power to be removed from the electric elevator driving
						  machine motor and brake, or from a hydraulic elevator machine, at a
						  predetermined distance from the terminal landing, and independently of the
						  functioning of the normal stopping device, the operating device and normal
						  terminal stopping device, if the normal terminal stopping device does not slow
						  down the car as intended.
Terminal Stopping Device, Final. A device which
						  automatically causes the power to be removed from an electric elevator or
						  dumbwaiter driving machine motor and brake, or from a hydraulic elevator or
						  dumbwaiter machine, independently of the functioning of the normal terminal
						  stopping device, the normal stopping device, the operating device, or any
						  emergency terminal stopping device, after the car has passed a terminal
						  landing.
Terminal Stopping Device, Machine Final. A final
						  terminal stopping device operated directly by the driving machine.
Terminal Stopping Device, Normal. A device or devices
						  used to slow down and stop an elevator or dumbwaiter car automatically at or
						  near a terminal landing independently of the functioning of the normal stopping
						  device or the operating device. The device includes the terminal stopping
						  switch, together with such terminal slow-down switches necessary to stop the
						  car at or near the terminal landing.
Threshold Comb, Moving Walk. The toothed portion of a
						  threshold plate designed to mesh with a grooved treadway surface.
Threshold Plate, Moving Walk. That portion of the
						  landing adjacent to the treadway consisting of one or more stationary or
						  slightly movable plates.
Transom. A panel or panels used to close a hoistway
						  enclosure opening above a hoistway entrance.
Travel or Rise. The vertical distance between the
						  bottom terminal landing and the top terminal landing of an elevator,
						  dumbwaiter, escalator, and inclined lift.
Traveling Cable. A cable made up of electric conductors
						  which provides electrical connection between an elevator or dumbwaiter car and
						  a fixed connection in the hoistway.
Treadway, Moving Walk. The passenger-carrying member of
						  a moving walk.
Truck-Zoning Device, Elevator. A device which will
						  permit the operator in the car to move a freight elevator within the truck zone
						  with the car door or gate and a hoistway door or gate open.
Truck Zone, Elevator. The limited distance above an
						  elevator landing within which the truck zoning device permits movement of the
						  elevator car.
Unlocking Zone. A zone extending from the landing floor
						  level to a point not less than 3 in. (76 mm) nor more than 18 in. (457 mm)
						  above or below the landing.
U-Groove. A shape of groove used on the drive sheave of
						  a double wrap traction machine, approximately a semicircle, with a radius
						  approximately equal to the diameter of the hoist rope.
Undercutting. A process of removing, by sawing or
						  scraping, part of the mica until it is below the surface of the copper of a
						  commutator.
Undercut U-Groove. A modified V-groove which has the
						  lower sides cut in the shape of a U.
Valley Break. A broken wire in a wire rope in which the
						  outside wire of a strand breaks in the immediate vicinity of the point where it
						  contacts a wire or wires of an adjacent strand, generally at a point not
						  visible when the wire rope is examined externally. One end of the broken wire
						  is long enough to reach from one valley to the next one and the other end of
						  the broken wire generally cannot be seen.Vane.
(1) A thin piece of metal attached to a
						  stationary structure in the hoistway to provide the actuating part of a
						  magnetically operated switch assembly mounted on the car. These switches are
						  used to perform several functions.
(2) A device mounted on a car door panel to
						  transmit door operating power to the hoistway door.
Volatile Memory. Memory lost when operating power is
							 removed.
V-Groove. One form of traction sheave groove which is
							 contoured in the shape of a straight-sided, flat bottom V.
Vision Panel. A small glass panel located in entrance
							 doors to permit the passengers or attendant to see when the car has reached the
							 landing. Waiting-Passenger Indicator. An indicator which shows at which
							 landings and for which direction elevator hall stop-or-signal calls have been
							 registered and are unanswered.
