Technical Features:

The JTK-type mine winder adopts controlling the on-off of AC contactors to switch resistors for speed adjustment. This mine winder comes in two structural types: integrated and separated. It is equipped with two sets of braking devices — manual brakes and electromagnetic brakes — which work independently to provide double protection, complying with the requirements specified in the Coal Mine Safety Regulations.

Featuring a compact structure, small volume, and convenient and flexible operation, the winder is also fitted with rope anti-slip protection, locking devices, a depth indicator, fault protection functions, etc.
