3.2.5 For high-rise elevators, the guide rails can be installed and adjusted in order to prevent errors caused by reference lines. And then to the car rail to determine the location of the ground installation. Methods as below:

3.2.5.1 in the center of the center M point 1 / 2L

M1 and M2 are marked (L is the car track spacing).

3.2.5.2 When installing the ground, the size of the front door side of the two doors measuring the door distance using a rectangular ruler is B + H-d / 2

(Usually 25mm or 30mm); width of the rail face. The width of the door is from the car center to the outside of the car;

3.2.5.3 Move the door to the bottom of M1, align the ruler of M2 and outer corner,

Set the OK (Figure 5-58). However, in order to check the center of the hall is correct, you can measure the distance between the center of the door and the two corners of the car. S1 and S2 should be equal (Figure 5-59).

3.3 installation of posts, slides, door sets

3.3.1 Cantilever concrete mounting column after the hard column. The brick wall is full of bolts (Figure 5-60).

3.3.6 steel door sets to adjust the installation, with steel bars will be inside the door and the wall of steel reinforcement welding (Figure

5-64).

3.4 installation hall door, adjust the hall door:

3.4.1 Place the door guide and door pulley on the door leaf to set the eccentric wheel to the maximum (and the maximum distance from the slide). And then put the bottom of the guide foot into the bucket, the door wheel hanging on the slide.

3.4.2 A 6 mm thick support is placed between the door leaf and the ground. There is a special pad between the door pulley frame and the door leaf

And then adjust the connecting screws of the pulley frame and the door leaf, turn the eccentric wheel back to a distance of less than 0.5 mm from the chute, remove the pad between the door leaf and the ground, Glide test, to achieve light and easy to pass (Figure 5-65).
