§ 14-16-109. Operation and control.

A.

Operating devices accessible for hoistway. Power elevators operated by ropes, cables, rods or any other devices which are accessible from the outside of the hoistway shall either:

1.

Have these operating devices made inaccessible from the outside of the hoistway; or

2.

Be equipped with all automatic operation equipment and operating device safeguards required by subsection (I)(2) of this section.

B.

Wheel or lever operating devices. Wheel or lever operating devices shall be provided with up and down position indicators on the operating device.

C.

Hand-rope cable sheave guard. Sheaves for hand-rope cables shall be equipped with guards to prevent the ropes from leaving the sheaves or the hand-rope cable tension shall be automatically maintained.

Overhead tension weights for hand-ropes shall be secured by cables or chains fastened to the weights and to a suitable anchorage. Hand-rope cables shall be kept smooth, clean, free of oil or grease and without projecting wires.

D.

Car switch operating device. All operating devices of car switch operating elevators shall automatically return to the stop position when pressure is released.

E.

More than one operating system. Elevators equipped with more than one operating system shall have the operating systems interlocked to allow the use of only one operating system at a time.

Exception: automatic operation elevators.

F.

Emergency stop switch. Electro-hydraulic and electric elevators which have an elevator machine provided with an electrically released brake shall be provided with an emergency stop switch in the car and this switch should be of a type in which the contacts are mechanically opened and not solely spring opened.

Exceptions:

1.

Automatic operation elevators equipped with a stop button so marked, in the car;

2.

Sidewalk or platform elevators.

G.

Defective contacts. Contacts which are badly pitted, burned, cracked or broken or which indicate a condition leading to possible fusing together of the contacts shall be renewed.

H.

Circuit breaker connected to fire alarm system. No circuit breaker operated automatically by a fire alarm system shall interrupt the operating circuit of a passenger elevator.

I.

Automatic operation elevator. Automatic operation elevators shall conform with the following:

1.

If the car has started for a given landing, no impulse can be given to send the car in the reverse direction.

2.

The car cannot be started by the operating devices unless the car door or gate is closed and is equipped with a contact as provided in section 14-16-98(A) and all hoistway doors or gates are closed and are equipped with either interlocks or with contacts and car operated mechanical locks and as required by either section 14-16-79(D) or (E) or section 14-16-86(A).

Exception: floating platform construction may be used on passenger elevators to permit the car to be operated from the landing buttons with the car gate open and no passenger in the car, under the following conditions:

a.

The entire side of the hoistway opposite a car opening, including the doors, sills, lintels and spandrels shall be substantially flush (within tolerance of one-quarter inch).

b.

The operation of the car from the car buttons shall be prevented unless the platform is depressed and the car gate is closed.

c.

A weight of 30 pounds placed anywhere in the form shall cause it to function.

d.

The platform shall be so constructed that there is no pocket or recess to catch refuse or dirt under the platform or no horizontal opening at the car sides where refuse or dirt may block the car platform in its depressed position.

e.

The entire platform area within the car and the car threshold shall float.

f.

There are no handrails in the car.

g.

Hoistway door interlocks are provided as required by section 14-16-82(A)(2).

J.

C.P.P.B. operation. Continuous-pressure operation shall not be used for elevators unless they are provided with all safety devices required for automatic operation.

K.

Overload circuit breaker. If an overload circuit breaker is used for a direct-current elevator the opening of the motor circuit and the opening of the brake circuit shall occur simultaneously.

L.

Centering rope on rope or rod operating device. Each power elevator operated by a hand rope or rod operating device shall be provided with a centering rope which will insure the operating mechanism being placed in the stop position when it is desired to stop the car, and the car shall be equipped with an operating rope car lock arranged to engage (at all landings) stop buttons on the operating rope or rod. The centering rope shall be so located as to be available to the operator for the full travel of the car.

Exceptions:

1.

Electric elevators equipped with electrically released brakes and emergency stop switches in the car;

2.

Electric elevators equipped with electrically released brakes and hoistway door or gate interlocks or electric contacts or with car door or gate electric contacts;

3.

Sidewalk elevators.

M.

Sequence relay. Electric elevators equipped with electric brakes and operated by hand cables, levers or wheel operating devices, shall, if provided with car emergency switches, car door or gate electric contacts or hoistway door or gate interlocks or electric contacts, have the operating and control circuits so arranged that in the case of failure of power or the opening of the car or hoistway door or gate interlock or contact circuits of the opening of the car emergency switch while the car is running, it will be necessary to return the operating device to the off position before the car can again be started.
