1, the installation distance of the electric hoist should be 15 meters away from the lifting distance of the heavy object, such as the rod crane, the distance shall not be less than the mast height

　　2. The distance between the middle of the drum and the nearest guide pulley should be greater than 20 times the length of the drum. When the rope is wound around the drum, when the rope is wound around the middle of the drum, the rope should be perpendicular to the middle position line of the drum.

　　3, the wire rope must be firmly fixed with the drum, the minimum allowable diameter of the drum is 16 to 20 times that of the wire rope, when the wire rope is left to the required length, the wire rope left on the drum shall not be less than 3 rings. Sichuan Crane Factory - Chengdu Taili crane adopts self-made hoist, safe, stable and reliable.

　　4, the fixing of the hoist must be firm, solid and stable to prevent tipping and sliding when lifting objects.

　　5, hoist electrical control should be placed on the operator, all electrical equipment should be equipped with ground wire, to prevent electric shock, electrical switches need to be taken care of.

　　6. Before driving, check whether all parts of the hoist rotate quickly and whether the brake device is firm and sensitive.

　　7. The operator must be familiar with the performance and structure of the hoist, and when working with actual operation experience, no one is allowed to stand within two meters around the hoist, and no one is allowed to stand around the sides of the running rope and the guiding pulley.

　　8, when the hoist is running, the action should be smooth and symmetrical, lifting heavy objects should be slowly lifted when the running rope has been pulled tight, it is strictly prohibited to suddenly start and accelerate, and should check whether the rope buckle and the binding of the object is firm and reliable.

　　9. It is strictly prohibited to use the hoist for loading, and the heavy object shall not be suspended in mid-air. It is forbidden to stay or walk under the hanging object

　　10, the operation of the hoist should be strictly done, the signal is unknown, the steel rope runs off, the load brake is not working.

　　11, the winch stops working, to cut off the power, the master to zero, with the safety brake brake tight, running rope put wood points.
