1. The installation distance of electric hoist should be 15 meters away from the lifting distance of heavy objects. If a pole crane is used, the distance should not be less than the height of the mast.

　　2. The distance from the middle of the reel to the nearest guide block should be more than 20 times the length of the reel. Perpendicular to the center line of the drum.

　　3. The wire rope must be firmly fixed on the roller. The minimum allowable diameter of the reel is 16 ~ 20 times that of the wire rope. When the wire rope is left to the desired length, the number of turns of the wire rope left on the drum shall not be less than 3 turns. Sichuan Crane Factory - Chengdu Taili crane using self-made hoist, safe, stable and reliable.

　　4. The fixing of the winch must be reliable, firm and stable, and prevent toppling and slipping when lifting objects.
