Product purposes

Technical skills

1. According to the improvement process control requirements and signal instructions issued by the signal system, control the start-up, operation, deceleration, stop and

other processes of the hoist, running smoothly and reliably.

2. Meet the requirements of control process of elevator and various safety chain protection requirements.

3. Realize the travel monitoring of the hoist, with perfect depth and speed display control function.

4. Realize the requirement of vacuum and non-contact of the control device of the main loop control device, the hardware configuration is simple, the software

programming is flexible, the debugging is convenient and the maintenance quantity is small. The system has good dynamic performance and good performance.

5.Improve the mine chance the safety reliability and control technology, to reduce equipment failure rate, improve the production efficiency, reduce the labor intensity of

operators play an important role.


Safety protection and chain function

The safety loop locks up the operation condition of the hoist only when the external equipment runs normally and has the driving condition. The safety loop locks the whole

fault protection signal of the hoist. Once the failure occurs, the hoist is immediately put on the emergency brake.


Comprehensive backup protection function

1, using proximity switch on the operation of the hoist speed machine position of digital detection and control, improve the system control precision and reliability, and

speed generator is used to detect the speed, has the hardware protection.

2. The double loop of the safety circuit, the system has at least the software security loop, the hardware security loop. Implement lifting machine multiple protection.

3. Automatic transmission of position signals, such as deceleration, parking, overwinding signal, etc., important points such as deceleration, overvolume and so on, at

least two or more roads together.

4. Have the protection of the depth indicator failure protection, operation direction error protection, loose rope protection, lock protection, speed limit protection, and up

and down protection
