The Escalator Company shared the general civil engineering problem handling methods at the site:
1. The margin of the beam is too large: in this case, the actual size of the civil works can be satisfied by increasing the length of the upper and lower platforms of the escalator. The platform can be lengthened on one side, or the platform on both sides can be lengthened at the same time. The total length of the upper and lower platforms should not exceed 1000mm. When the platform is lengthened, pay attention to the length of the pit or the opening of the floor should also be lengthened. The force on the upper and lower support points will increase after the escalator is lengthened. If the beam margin increases too long, support should be added 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. The margin of the beam is too small: the total length of the escalator is shortened by shortening the lower platform, but the range of shortening is limited, generally not exceeding 200 mm. The upper platform can generally not 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 also shortens the beam margin.
3. There are beams or other obstacles directly above the escalator: Whether the beam or other obstacles "meet" can be judged according to the following formula (unit is mm): length of the hole - 50 - upper platform length) ÷ 1.732 or 1.428 - beam height ≥ 2300 : hole length and beam height (including decoration thickness) on-site measurement or user-provided; 50 is the gap between the escalator truss to the upper support beam (some manufacturers have a value of 40); constant 1.428 for 35-degree angle escalator; 1.732 for 30 degree angle escalator; the upper platform length is determined according to the manufacturer's standard layout; 2300 is the minimum height specified by the national standard. `" Note: The inclination of the escalator in the mall is generally not allowed to exceed 30 degrees.
4. The transportation passage in the building, the height of the doorway or the space for rotation in the building is not enough: in this case, if the civil works cannot be changed, the escalator must be transported in sections (generally divided into 2 sections), which should be specified when signing the sales contract. After the whole truss is delivered, it cannot be divided into sections. The escalator equipment is not allowed to be transported on the side.
5. Escalator power supply setting: three-phase 380V, 50HZ lead to the exit of the escalator.
6. Measurement of the moving walkway: The method is basically similar to the escalator, and is measured with reference to the manufacturer's standard layout drawing.
