Treatment of general civil problems at the escalator site of elevator handrail manufacturers


1.Beam margin is too large: In this case, the actual size of civil works can be met by increasing the length of the escalator's upper and lower platforms. The platform can be extended on one side, or on both sides at the same time. The total length of the upper and lower platforms should generally not exceed 1000mm. When lengthening the platform, pay attention to the length of the pit or the floor opening. After the escalator is lengthened, the stress on the upper and lower support points will also increase. If the beam margin is too long, support is needed in the middle of the escalator truss. In addition, changing the angle of the escalator from 35 degrees to 30 degrees can also make the beam margin longer.

2.Beam margin is too small: shorten the total length of the escalator by shortening the lower platform, but note that the shortened range is very limited, generally not more than 200mm. The upper platform cannot be shortened, because the upper platform contains equipment such as control cabinets and motors. Changing the angle of the escalator from 30 degrees to 35 degrees can also shorten the beam margin.
