ASME ASME Elevators and Escalators A17.1 3

Question 1

Which ASME A17.1 requirement defines the maximum stopping distance for an escalator's emergency stop?

Accepted Answer

Dependent on speed: 12 in at 90 fpm, 18 in at 120 fpm

Answer

ASME A17.1 specifies that escalator stopping distance must not exceed 12 inches at 90 fpm or 18 inches at 120 fpm rated speed.

Question 2

Under ASME A17.1, what is the maximum angle of inclination permitted for a standard escalator?

Accepted Answer

30 degrees

Answer

ASME A17.1 allows a maximum angle of inclination of 30 degrees for standard escalators (with 35 degrees allowed for limited-rise units under special conditions).

Question 3

What does ASME A17.1 require regarding the 'comb-plate' of an escalator?

Accepted Answer

It must mesh with the step grooves and be designed to deflect if an obstruction is caught

Answer

The comb-plate must interleave with the grooves in the escalator steps and is required to deflect or break away if an object becomes lodged, triggering an emergency stop.

Question 4

Which ASME A17.1 code section governs moving walks (horizontal escalators)?

Accepted Answer

Part 6

Answer

ASME A17.1 Part 6 covers the requirements for moving walks (passenger conveyors) including horizontal and inclined moving walks.

Question 5

Under ASME A17.1, what is the minimum illumination required at the escalator entrance and exit landings?

Accepted Answer

10 foot-candles

Answer

ASME A17.1 requires a minimum of 10 foot-candles of illumination at escalator entrance and exit landings for safe passenger use.
