(a) Construction of Hoistways and Hoistway Enclosures.
(1) Hoistways of hand elevators shall be enclosed as required for power-driven elevators in Section 3010(a).
(2) The strength of the hoistway enclosure shall be as required in Section 3010(b).
(3) The construction at the bottom of the hoistway shall comply with Section 3010(c).
(b) Machine Rooms and Machinery Spaces.
(1) Hand elevator machines may be located inside the hoistway enclosure at the top or bottom intervening enclosures or platforms. Machines of hand sidewalk elevators having a travel of not more than one story are not required to be enclosed.
(2) The access to machine rooms and machinery spaces shall comply with Section 3011(c) except that vertical ladders with handgrips may be used for access from building floors where the difference in level exceeds 3 feet.
(3) Permanent electric lighting shall be provided in all machine rooms or machinery spaces.
(c) Machinery and Sheave Beams, Supports, and Foundations.
The machinery and sheave beams, supports, and foundations shall comply with the requirements of Section 3015.
(d) Pits. A pit shall be provided at the bottom of every hand elevator hoistway. These pits shall extend the entire area of the hoistway and shall be of sufficient depth so that there will be not less than 12 inches clearance between the bottom of the pit and the underside of the elevator when the elevator is landed on the fully compressed buffers or bumpers. The pit shall be not less than 30 inches deep.
(e) Bottom and Top Clearances and Runby for Cars and Counterweights.
(1) The top car clearance shall be not less than the sum of the following:
(A) The bottom counterweight runby, if any.
(B) The stroke of the counterweight buffer where buffers are used.
(C) 12 inches.
(2) The top counterweight clearance shall be not less than the sum of the following:
(A) The bottom car runby, if any.
(B) The stroke of the car buffers where buffers are used.
(C) 6 inches.
(3) The top car clearance shall be not less than 18 inches with the platform level with the top landing.
(4) Bumpers or buffers shall be provided under all hand-powered elevators.
(f) Hoistway Clearance. The horizontal clearance between the car and the hoistway or the car and the counterweights shall comply with Section 3018 except that shear plates described in Section 3018(g) need not be provided when the car will not travel in the up direction with 150 pounds on the platform and the brake released.
(g) Protection of Spaces below Hoistways. The requirements of Section 3019 shall apply.
(h) Protection of Hoistway Landing Openings.
(1) Hoistway landing openings shall be provided with vertically sliding semi-automatic or full automatic gates not less than 66 inches high of a design that will reject a ball 2 inches in diameter. Gates shall be so constructed and guided as to withstand a lateral force of 100 pounds concentrated at the center of the gate without being deflected beyond the line of the landing sill, and a force of 250 pounds without forcing the gate from its guides or breaking the gate.
EXCEPTION: Where architectural conditions or necessary access to the operating rope preclude the use of 66 inch high gates, the following conditions are permitted.
1. A top landing full automatic gate may be not less than 41 nor more than 43 inches high.
2. A lowest landing full automatic gate not less than 41 nor more than 43 inches high may be used if it disappears into the pit.
3. Semi-automatic gates not less than 41 nor more than 43 inches high may be used at any landing.
(2) Where any gate less than 66 inches high is used at any landing other than the top landing, telltale chains or ropes not less than 4 feet long nor more than 5 inches apart shall be hung from the lower edge of the car platform adjacent to such gates.
(3) Slots in gates required for access to the operating rope or the brake rope or such slots in the hoistway enclosure shall not exceed 5 inches in width.
EXCEPTION: Elevators installed before June 5, 1947.
(4) Full automatic gates shall be provided with mechanical locks that prevent the gate from being opened unless the opening device is operated by the elevator car. Semi-automatic gates shall be provided with mechanical locks to prevent the gate from being opened unless the elevator car is within the landing zone.
