Pits are not required.
(a) self-closing or manually operated horizontally sliding or swinging, single section
(b) self-closing or manually operated horizontally swinging, two section (Dutch type) with one section above the other and the lower section extending not less than 1070 mm (42 in.) above the floor, and arranged to be opened only when the car is in the landing zone and after the upper section has been opened, and to be closed by the closing of the upper section
(c) manually operated vertically sliding counterweighted single or multisection
(d) manually operated vertically sliding biparting counterbalanced
Manually operated doors shall be equipped with approved devices to close them automatically when released by the action of heat. Self-closing doors equipped with hold-open devices shall be equipped with fusible links that will release the door in case of excessive heat.
Landing doors shall be provided with mechanical locks arranged so that the car cannot leave the landing unless the door is closed. The lock or latch shall be arranged to ensure that the door is in a position to be locked when or before the car leaves the landing.
Hoistway landing openings equipped with horizontally sliding or swinging doors shall also be provided with vertically sliding semiautomatic gates, not less than 1070 mm (42 in.) high and of a design that will reject a ball 50 mm (2 in.) in diameter. Gates shall be constructed and guided to withstand a lateral force of 445 N (100 lbf) concentrated at the center of the gate without being deflected beyond the line of the landing sill, and a force of 1112 N (250 lbf) without forcing the gate from its guides or causing it to break or be permanently deformed.
(b) General Design Requirements. The lock shall hold the gate in the closed position by means of gravity or a restrained compression spring, or both.
(c) Closed Position. Hoistway gates provided with hoistway gate separate mechanical locks shall be considered to be in the closed position when the gate is within 10 mm (0.375 in.) of contact with the landing sill.
Cars shall be enclosed on the sides not used for entrance. The deflection of the enclosure shall be not more than 6 mm (0.25 in.) when subjected to a force of 334 N (75 lbf) applied perpendicularly to the car enclosure at any point. The enclosure shall be secured to the car platform or frame in such a manner that it cannot work loose or become displaced in ordinary service.
These requirements do not apply to sidewalk elevators.
Car frames and platforms shall be metal or sound seasoned wood designed with a factor of safety not less than 4 for metal and 6 for wood, based on the rated load uniformly distributed. Connections between frame members of the car frame and the platform shall be riveted, bolted, or welded.
Elevator cars on which an operator is permitted to ride shall have not more than one compartment.
Elevator cars on which persons are permitted to ride shall not be arranged to counterbalance each other.
(a) rated load in kilograms (pounds)
(b) the maximum number of passengers to be carried based on 68 kg (150 lb) per person (if a passenger elevator)
(c) suspension data required by 184.108.40.206
(a) the guide rails and their fastenings shall not deflect more than 6 mm (0.25 in.) under normal operation
(b) the guide rails and their fastenings shall withstand the application of the safety, where provided, when stopping the car with rated load or when stopping the counterweight
