2.26.1 Operation and Operating Devices
22.214.171.124 Additional Operating Devices for Elevators Equipped to Carry One-Piece Loads Greater Than Their Rated Load
(-a) on the top of the car
(-b) atthe inspection and test panel when required by 126.96.36.199.2(h)
(-a) in the car
(-b) in a machinery space outside the hoistway
(-c) in a machine room
(-d) in a control space outside the hoistway
(-e) in a control room
(-f) in the pit in accordance with 188.8.131.52
(-g) at a working platform in accordance with 184.108.40.206
(1) be manually operated
(2) be labeled "INSPECTION"
(3) have two positions, labeled "INSPECTION" or "INSP" and "NORMAL" or "NORM"
(4) when in the "INSPECTION" position
(-1) through a contact that is positively opened mechanically; their opening shall not depend solely on springs
(c) Inspection operating devices shall be
(1) the continuous-pressure type
(2) labeled "UP" and "DOWN," respectively
(d) Inspection operation shall conform to the following:
(1) The speed of the car shall not exceed 0.75 m/s (150 ft/min).
For elevators with static control, a means independent from the normal means to control the speed shall be provided to limit the inspection speed to a maximum of 0.75 m/s (150 ft/min), should the normal means to control this speed (mechanical, electrical, or solid-state devices) fail to do so.
The car speed-sensing device used for the means to limit the speed of the car while on inspection operation shall be permitted to be either a separate car speed-sensing device from that of the normal speed control system or the same car speed-sensing device, provided that a separate means is used to continuously verify the proper operation of this speed-sensing device. Where the same car speed-sensing device is used, the detection of a failure of this car speed-sensing device while on inspection operation shall cause the power to be removed from the driving-machine motor and brake.
The car speed-sensing device(s) and, where required, the verification means described above shall conform to the following:
(-a) A common actuating means (e.g., a driving-machine shaft or brake drum) shall be permitted, provided that it is not dependent on any of the following connection types, unless the connection is continuously monitored:
(-2) friction (except for interference fits)
(-3) a flexible coupling where positive engagement is not assured between coupling halves
Where monitoring is required, the monitoring shall detect a failure that prevents conformance with this requirement while on inspection operation and shall cause the electric power to be removed from the elevator driving-machine motor and brake.
(-b) A common member (e.g., tape, target, or wire) that is sensed by both speed-sensing devices shall be permitted, provided that
(-1) the member is monitored such that when its presence is not detected while on inspection operation, this shall cause the electric power to be removed from the elevator driving-machine motor and brake
(-2) the common member is securely mounted in such a manner that horizontal movement of the car shall not affect the operation of the sensors
(-c) A common mounting means shall be permitted.
(3) Fully closed doors shall be permitted to be held in the closed position with power applied.
(b) The transfer switch [see 220.127.116.11.1(b)] shall be located on the car top and shall be designed to prevent accidental transfer from the "INSPECTION" position to the "NORMAL" position.
(d) The inspection operating devices shall become effective only when the "ENABLE" device is activated.
(1) the "ENABLE" device [see [c)] and a stop switch, in addition to the stop switch required in (a), are included in the portable unit
(2) the flexible cord is permanently attached so that the portable unit cannot be detached from the car top
(f) Separate additional devices of the continuous-pressure type shall be permitted to be provided on the car top to make power door opening and closing and automatic car leveling operative from the top of the car for testing purposes.
(g) When on top-of-car inspection operation, a separate additional device shall be permitted to render ineffective the top final terminal stopping device, and the buffer switch for gas spring-return counterweight oil buffers, in conformance with the requirements of 18.104.22.168, 22.214.171.124, 126.96.36.199.1(a), and 188.8.131.52, and it shall allow the car to be moved to a position in conformance with the requirements of 184.108.40.206 and 220.127.116.11.3(c).
(a) shall be located in the car.
(b) shall be key-operated or placed behind a locked cover. Keys to operate or access the switch shall be Group 1 Security (see Section 8.1).
(c) shall be rendered ineffective if top-of-car inspection operation is activated.
(d) when in the "INSPECTION" position, shall not enable hoistway access switch(es). A third switch position labeled "ACCESS ENABLE" shall be permitted to enable the hoistway access switches (see 18.104.22.168.1).
22.214.171.124.4 Machinery Space Outside the Hoistway, Machine Room, Control Space Outside the Hoistway, Control Room, Pit, Landing, and Working Platform Inspection Operations
(a) The transfer switch [see 126.96.36.199.1(b)] shall be
(3) located in the machinery space outside the hoistway, in a machine room, in a control space outside the hoistway, or in a control room, as applicable
(4) located at a working platform where required by 188.8.131.52 (Working Platform Inspection Operation)
(5) rendered ineffective if top-of-car inspection operation, in-car inspection operation, or hoistway access operation is activated, or when a car door or hoistway door bypass switch is in the "BYPASS" position
(b) Only one mode of the inspection operation as described in (a)(1) through (a)(4) shall be permitted to be operative at any time. If more than one inspection operation transfer switch, as permitted in (a)(1) through (a)(4), is in the "INSPECTION" position, the controls shall prevent operation of the car from any location as described in (a)(1) through (a)(4).
(c) Pit inspection operation, where provided, shall also conform to 184.108.40.206.2(c) and 220.127.116.11.2(d). When the pit transfer switch is in the "INSPECTION" position, the controls shall prevent operation of the car when any inspection transfer switch, other than that in the pit, is in the "INSPECTION" position, or when hoistway access operation is enabled.
(d) Where inspection operation from a working platform is provided and the working platform transfer switch is in the "INSPECTION" position, the controls shall prevent operation of the car when any other inspection transfer switch, other than that at the working platform, is in the "INSPECTION" position, or when hoistway access operation is enabled.
(b) the inspection and test panel (see 27.6.5)
The switches shall prepare the control system so that, only when top-of-car or in-car inspection operation is activated, the car shall be permitted to be moved with the door closed detection means or door locked detection means bypassed. The switches shall conform to 18.104.22.168.1 through 22.214.171.124.8.
(a) have contacts that are positively opened mechanically; their opening shall not be solely dependent on springs
