Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) Types of doors and gates permitted.
(1) Where both a hoistway door and a car door or gate are opened and/or closed by power, the hoistway door and the car door or gate shall:
(A) Both be of the horizontally sliding type or
(B) Both be of the vertically sliding type.
(b) Power Opening.
(1) Power opening of a car door or gate shall be subjected to the following:
(A) Power opening shall occur only when the car is at rest at the landing or is leveling except that on elevators with static control, power shall not be applied to open car doors until the car is within 12 in. (305 mm) of the landing.
(B) Collapsible-type car gates shall not be power opened to a distance exceeding 1/3 the clear gate opening, and in no case more than 10 inches.
(C)
Existing power-operated, collapsible car gates shall be provided with a means to prevent shear.
(2) Power opening of a hoistway door shall conform to the following:
(A) Power opening shall occur only at that landing where the car is stopping, is leveling, or is at rest; and shall start only when the car is within the landing zone or is within 30 in. (762 mm) above or 30 in. (762 mm) below the landing where an automatic car leveling device is provided, except that on static control elevators, opening shall not begin until the car is within 12 in. (305 mm) of the landing.
(B) Power opening may be initiated automatically through control circuits provided that when stopping under normal operating conditions, the car shall be at rest or substantially level with the landings before the hoistway door is in the fully open position.
(C) Sequence opening of a vertically sliding, biparting hoistway door and adjacent car gate shall be provided where required by section 3022(e)(1).
(c) Power Closing.
(1)
Where a car door or gate is closed by power, or is of the automatically released, self-closing type and faces a manually operated or self-closing hoistway door, the closing of the car door or gate shall not be initiated unless the hoistway door is in the closed position.
EXCEPTION TO SUBSECTION 3022(c)(1):
Where a car door or gate is closed by power through continuous pressure of a door closing switch, or of the car operating device, and where the release of the closing switch or operating device will cause the car door or gate to stop or to stop and reopen.
(A) The closing mechanism shall be so designed that the force necessary to prevent closing of a horizontally sliding door or gate from the rest shall be not more than 30 lbf (133 N).
(2) Horizontally sliding or vertically sliding biparting hoistway doors may be closed by continuous pressure means subject to the following:
(A) The release of the closing means shall cause the hoistway door and a power-operated or power-closed car door or gate 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 1/2 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.
