Chapter VI Safety Technology of Escalators Section 1 Structure and Main Parameters of Escalators I. Structural Features and Classification of Escalators 1.
Structure Features Escalator is an open transport machinery that is driven by electric power and capable of transporting passengers in large numbers in a certain direction.
With a compact, safe, reliable, easy installation and maintenance features.
Therefore, in large passenger flow and concentration of places, such as stations, terminals, shopping malls, etc., to be widely used.
2.
Classification Escalator classification many ways, from different angles.
(1) According to the drive type: a chain (end drive) and rack and pinion (intermediate drive) two categories.
(2) According to the conditions of use: There are ordinary type (less than 140h run time per week) and public transport type (more than 140h run time per week).
(3) According to the lifting height points: a small lifting height of up to 8m, a lifting height of up to 25m and a large lifting height of up to 65m.
(4) According to the operating speed points: There are two kinds of constant speed and speed.
(5) According to the running track points: there are straight (traditional), spiral, runway and rotary spiral type 4.
Second, the main parameters of escalators and components 1.
The main parameters (1) rated speed (Y /): rung in the case of no-load speed (m / s).
Typically 0.5 m / s, 0.65 m / s and 0.75 m / s.
(2) Inclination (
