First of all, the inclination angle of an escalator refers to the angle between the running route of the steps in the inclined section and the horizontal plane. Article 10.1.1 of the European standard EN 115 clearly stipulates this value: the inclination of the escalator The angle cannot exceed 30°, and it is allowed to increase to 35° for escalators whose running speed does not exceed 0.5m/s and whose lifting height does not exceed 6m.
With the same lifting height, a 35° escalator occupies a smaller shopping mall space than a 30° escalator. Therefore, some profit-oriented businesses prefer 35° escalators.
The recommended ratio of step height to step distance of 16/31 is converted into an angle of 27.3°. At present, the ratio of step height to step distance of ordinary stairs commonly used in some buildings is 16/31. Obviously, if escalators and ordinary stairs are arranged side by side in a shopping mall, the escalator with a 27.3° configuration will look more harmonious.
Extended information:
The driving machine is mainly composed of an electric motor, a worm gear reducer, a sprocket, a brake (brake), etc. The installation position of the motor can be divided into vertical and horizontal types. Currently, most escalators use vertical drivers.
The advantages are: compact structure, small footprint, light weight, easy maintenance; low noise and low vibration.
Especially for the integrated driver, the motor rotor shaft and the worm shaft are connected to each other, so the balance is very good, and it can eliminate vibration and reduce noise; the escalator with large load-bearing capacity and small lifting height can be driven by one It is driven by one driving machine, and the escalator with medium lifting height can be driven by two driving machines.
