The basic parameters of escalators, moving walkways
( 1 ) Theoretical transmission capacity . Refers to the number of theoretical transported per hour. Theoretical transmission capacity (c, human / h) calculated as c = 3 600vk/0.4. Where , v is the rated speed , m / s; k is the width of the coefficient ( when taking 1.5,1.0 m rung when taken 1.0,0.8 m = 2.0 when the width of 0.6m ) .
( 2 ) the rated speed. Refers to the steps, pallets or belt speed under no-load operation , and is designed to determine the actual operating speed. Escalator tilt angle no greater than 30 ° should not exceed the rated speed of 0.75m / s, tilt angle greater than 30 ° and not more than 35 ° shall not exceed the rated speed of 0.50m / s. Walkway shall not exceed the rated speed of 0.75m / s, when the pedal does not exceed the width of 1.1m, is allowed to reach the maximum rated speed of 0.9m / s.
( 3 ) the tilt angle . Maximum angle steps, pallets or tape running direction of the horizontal surface . When the inclination angle should not exceed the escalator 30 °, when the lifting height of not more than 6m, does not exceed the rated speed of 0.50m / s, to allow the inclination angle 35 °. Tilt angle generally use 30 °, 35 °, 27 ° and other series. Walkways tilt angle should not exceed 12 °.
( 4 ) lifting height . Import escalator floor plate vertical distance between the two .
( 5 ) Step a nominal width . Domestic escalators generally use 0.6m, 0.8m, 1.0m, corresponding to an average person carries each rung , 1.5 people, 2 people.
