     1. the length of the beam is too large: the case can be increased by increasing the length of the upper and lower platforms. Can be extended to one side of the platform, but also on both sides of the platform at the same time, the total length of the upper and lower platforms are generally not more than 1000mm. The platform extension should pay attention to the pit length or floor opening should also be extended. The stress at the upper and lower support points will also increase. If the distance between the beam and the beam is increased, the middle of the ladder truss should be supported. In addition to the angle from the angle of 30 degrees to 35 degrees can also make the beam edge distance. .
     2. beam edge distance: by shortening the platform to shorten the total length of the ladder, but the range is limited to shorten the range is very limited, generally not more than 200mm. On the platform generally can not be shortened, because the platform contains control cabinet and motor and other equipment. The escalator angle from 30 degrees to 35 degrees can also shorten the beam margin.
     3. On the escalator is above the beam or other obstacles: beam or other obstacles whether "met" can be according to the following formula to determine (unit: mm): hole length - 50 - ping director) 83019 1.732 or 1.428 - beam height is equal to or more than 2300 of which: the hole and the length of the beam high (including the thickness of the decoration) to provide field measurements or user; 50 for escalator truss to support beam edge gap (some manufacturers the value of 40); constant 1.428 for 35 degree angle escalator; 1.732 for 30 degree angle escalator; platform long determined according to the manufacturer's standard layout; 2300 for national standards for the minimum height. "Note: the slope of the mall is generally less than 30 degrees.
    4. Building transport channel, height of door or building space rotary enough: this case, if construction can not be changed, then escalator factory must be segmented transport (generally 2 knots), at the time of the signing of the sales contract to indicate. The whole factory is not segmented truss, escalator equipment is not allowed to carry on.
    5. escalator power supply settings: three phase 50HZ, 380V to lead to the escalator on the exit.
    6. automatic sidewalk measurement: the method is similar to that of the escalator, which is measured by reference to the manufacturer's standard.
