1. Draw a line at both ends of the Underground Mining Scraper Winch rod section through the top of the boom section, perpendicular to its length, and then take the middle point on the line.
2. Check the following steps to see if the lifting mechanism is exactly perpendicular to the boom: from a point on the center line of the outer boom, draw a line with chalk through the center line of the base and the reel.
3. Lower the Underground Mining Scraper Winch arm to a horizontal position.
4. Pull a line at the top of the lifting drum to keep it parallel to the axis of the drum. The steps are as follows:
Using Mira alloy styli, take a 0 ° measuring point on each flange of the top of the reel. Note: If it is not appropriate to use this special equipment, close to the inner surface of the cutting of the two drum flanges, Underground Mining Scraper Winch? That is, sufficient centering accuracy is obtained. Draw a line between the flanges of the drum of the lifting mechanism, penetrate the two points on it, how to adjust and then take the middle point on the line.
