| A.The minimum safety coefficient of the wire rope conforms to the following provisions: 1.Specially for lifting people 9 times .2. Lifting personnel and materials (9 times when lifting personnel, 7.5 times when lifting materials);3, Specially for lifting materials 6.5 times. | ||||||||||||||||||||
| B.The ratio of the diameter of the winch drum to the diameter of the wire rope shall not be less than 80 times;The ratio of drum diameter of downhole winch shall not be less than 60 times. | ||||||||||||||||||||
| C.The number of layers of wire rope winding on the drum shall comply with the following provisions: 1. One layer of lifting personnel and materials in the vertical shaft , two layers specially for lifting material . 2. Two layers of lifting personnel and materials in the inclined shaft , three layers specially for lifting materials .3.

The single rope mine hoist system is mainly used for vertical shaft , inclined shaft to lift people , materials and equipments in coal mines , metallic mines and non-metallic mines . It can also be used for traction transportation .
a.The working conditions of the single drum mine hoist system The mine hoist system shall be installed in the machine room with air temperature 0°C-40°C, relative humidity not more than 85% (ambient temperature 20°C±5°C) , the altitude not more than 1000m . It shall be able to prevent liquid from immersing into the internal of the electric appliance and work in the environment without violent vibration , jolt or corrosive gas . When the altitude exceeds 1000m , the cooling effect of air and the decrease of dielectric strength shall be considered . The selected electrical equipment shall be designed or used according to the agreement between the fabricator and user .
b.The layer of drums on the mine hoist system :
(1)1 Layer used to lift people or lift people and materials in vertical shaft ; 2 layer is used to lift materials.
(2)2 layers is used to lift people and materials in inclined shaft , 3 layers is used to lift material .
(3)The connection point which the rope transfers from the lower to the upper (equivalent to a quarter of the loop ) must be checked frequently and the rope should be moved quarter of the loop every three months .
Note:
(1) JK model mine hoist system is strictly prohibited for gas, coal dust and other inflammable , explosive gas places ! JKB can be used in above conditions.
(2) The mine hoist system is strictly prohibited from overload operation !
(3) Overspeed and power failure are strictly prohibited !
