Single-Rope Winding Type Mine Hoisting Machine
Hoisting Machine Applications:
This series of machines are fixed equipments in coal mine, metal mine and nonmetallic mine. They are used for lifting and lowering coal, mineral, workers, material, equipments. etc. And they can also be used for other hauling transportation purpose.

Working principle:
The motor drives the reducer and then the power is transmitted to the winding drum, which winds the steel rope, so the lifting and lowering of container are realized; the speed is controlled by electrified transmission, the disc brake is controlled by hydraulic and electrified controller; there is location indicating system to indicate the container depth; there are a variety of transducers and control units, composing the joint mechanical, electric and hydraulic control system, which supervise and protects the whole equipments; computer and network technology is applied to transfer the information between the outside and the inside of the hoister.

Technical features:
1. Having a variety type of winding drum: integral type, two valve type and four piece type
2. Winding drum rope groove is spiral groove compacted by engineering plastic lining, and equipped with steel rope transition device between the layers.
3. Applying the oil cylinder postpositioned disc brake, joint controlled by electric-hydraulic; two types of hydraulic station: medium-pressure and middle & high-pressure. Each type of hydraulic station also has two braking methods: constant braking torque, electrified delay and hydraulic delay, secondary braking; constant speed reduction and constant braking torque, secondary braking. The hydraulic station can be equipped with pressure transducer and pressure relay.
4. The main shaft and winding drum apply plane great torque friction connection.
5. Having signal supervising and control unit composed of photoelectric encoder, autosyn and low speed DC speed indicating generator, capable of supervising over speed, over winding, depth indicator failure, brake block wearing, and spring fatigue. etc. These also play as a good protector.
6. Two kinds of operating floor: integral type and split type. All apply integrated signal light, electric instrument of reliable performance, new model integral type joystick and depth indicating system of digital depth indicator and digital and screw integrated depth indicator. All have exclusive table for Industrial TV or computer, printer. etc.
7. The hoisting sheave units apply one-piece casting structure or two-piece welding structure, supported by rolling bearing and equipped with PVC or PA friction gasket on the rim.
8. Can be equipped with mine hoister network control and remote diagnosis system.

Supply range of complete set:
Main machine, hoisting sheave unit; different type of operating floor, depth indicator, hydraulic station, lubrication station; electrical dragging and control system, information transfer system. We can also manufacture equipments of other specifications, to meet the customer' s requirements.
