to stop or to stop and reopen.
(B)
The operation of the closing means at any landing shall not close the hoistway
door at any other landing nor the car door or gate when the elevator is at any
other landing.
(C) For elevators
having more than one hoistway opening at any landing level, a separate closing
means shall be provided in the car for each car door or gate and its adjacent
hoistway door. Any closing means at a landing shall close only that hoistway
door and the car door or gate at the side where such means is located.
EXCEPTION TO SUBSECTION
3022(c)(2)(C):
A separate closing means need not be furnished in the
car for a horizontally sliding hoistway door and adjacent car door or gate
which conform to the requirements of section
3022(c).
(D) Sequence closing of a vertically sliding,
biparting hoistway door and adjacent car gate shall be provided where required
by section
3022(f).
(E) Vertically sliding biparting hoistway
doors shall be used only in conjunction with a vertically sliding car gate that
is closed by similar means.
(3) Power closing by momentary pressure or by
automatic means of horizontally sliding hoistway doors or car doors or gates
shall be permitted only for automatic or constant-pressure operation elevators.
The closing of the doors or gates shall be subject to the following:
(A) It shall conform to the requirements of
section
3022(d).
(B) A momentary pressure switch shall be
provided in the car, the operation of which shall cause the doors to stop or to
stop and reopen.
(4)
Power closing of vertically sliding, biparting hoistway doors by momentary
pressure or by automatic means shall be subject to the following:
(A) Only in conjunction with a vertically
sliding car door or gate that is closed by a similar means.
(B) A warning bell or other audible signal
shall be provided on the car which will start to sound at least 5 seconds
before the car door or gate starts to close and shall continue to sound until
the hoistway door is substantially closed.
EXCEPTION TO SUBSECTION
3022(b)(4)(B):
The 5-second time interval may be omitted when the
doors are closed by a switch in the car.
(C) Sequence closing of the hoistway door and
the adjacent car gate shall be provided and shall conform to the requirements
of section
3022(f).
(D) The car gate shall be equipped with a
reopening device conforming with the requirements of section
3022(e).
(E) A momentary-pressure type switch shall be
provided in the car and at each landing which, when operated, shall cause the
hoistway doors and the car gate to stop or to stop and reopen.
(F) The average closing speed shall not
exceed 1 fps (0.305 m/s) for each panel of a biparting, counterbalanced
hoistway door and shall not exceed 2 fps (0.62 m/s) for a vertically sliding,
counterweighted car gate.
(5)
Car doors shall be arranged to be
opened manually from inside the car in the event the power supply to the
elevator is disconnected.
(d) Kinetic Energy and Force Limitations for
Power Door Operators Used With Horizontally Sliding Hoistway Doors and
Horizontally Sliding Car Doors or Gates. Where a power-operated, horizontally
sliding hoistway door is closed by momentary pressure or by automatic means or
is closed simultaneously with another door from one continuous pressure means,
the closing mechanism shall be designed and installed to conform to the
following requirements:
(1) The kinetic energy
of the hoistway door and all parts rigidly connected thereto, computed for the
average closing speed, shall not exceed 7 ft-lbs (9.49 J) where a reopening
device for the power-operated car door or gate conforming to the requirements
of section
3022(e) is used,
and shall not exceed 2 ½ ft-lbf (3.39 J) where such door reopening
device is not used.
Where the hoistway door and the car door or gate are
closed in such a manner that stopping either one manually will stop both, the
sum of the hoistway and the car door weights, as well as all parts connected
rigidly thereto, shall be used to compute the kinetic energy.
The average closing speed shall be determined by timing
the closing door as follows:
(A) With
single-slide and two-speed doors, determine the time required for the leading
edge of the door to travel from a point 2 in. (51 mm) away from the open jamb
to a point 2 (51 mm) away from the opposite jamb.
(B) With center-opening or two-speed
center-opening doors, determine the time required for the leading edge of the
door to travel from a point 1 in. (25 mm) away from the open jamb to a point 1
in. (25 mm) from the center meeting point of the doors.
(2) The force necessary to prevent closing of
the hoistway door (or the car door or gate if self-closing or power-operated)
from rest shall be not more than 30 lbf (133 N). This force shall be measured
on the leading edge of the door with the door at any point between one-third
and two-thirds of its travel.
(3)
The weight of the doors and all parts rigidly connected thereto shall be
submitted to the Division of Occupational Safety and
Health.
(e) Reopening
Device for Power Operated Car Doors or Gates. Where required by section
3022(c)(4)(D) or
section
3022(d)(1), a
power-operated car door or gate shall be provided with a reopening device which
will function to stop and reopen a car door or gate and the adjacent hoistway
door in the event that the car door or gate is obstructed while closing.
For center-opening doors, the reopening device shall be
so designed and installed that the obstruction of either door panel, when
closing, will cause the reopening device to function.
(f) Sequence Operation for Power Operated
Hoistway Doors With Car Doors or Gates.
(1)
Sequence operation shall be provided under the following
conditions:
(A)
Sequence
opening and closing shall be provided for power-operated vertically sliding
biparting counterbalanced doors where used on passenger elevators in
conjunction with a power-operated vertically sliding car
gate.
(B)
Sequence
closing shall be provided for power-operated, vertically sliding biparting
hoistway doors and vertically sliding car gates which are closed by momentary
pressure or by a timing device.
(2)
The sequence operation of a
vertically sliding, biparting hoistway door and adjacent power-operated
vertically sliding car gate shall conform to the following:
(A)
In opening, the hoistway door
shall be opened at least
2/3 of its
travel before the car gate can start to open.
(B)
In closing, the car gate shall be
closed at least
2/3 of its
travel before the hoistway door can start to close.
