1. Adopt Magnetic Coupler as the synchronous differential mechanism with good reliable synchronization of cable deploying and retracting.

2. Widely used to cables deploying and retracting of different traveling equipments synchronously.

3. Long vertical deploying and retracting distance , 150m at most.

4. Controlling Model of cable reel: the motor works when retracting ,while stops when deploying

5. Simple structure, small weight & size, easy-installation and long life.
