Conveyorized Fully Automatic Rotary Arm Stretch Wrapping System

Model: WCRT-175

 

The WCRT-175 model is an automatic conveyorized rotary tower. All you need to do with this system is change the roll of film. It can keep up with the most demanding production rates and wrap almost anything. Since the load remains stationary, this system is ideal for wrapping very light, very heavy, tall, or unstable loads. It is also great in wash down and dusty applications. Wulftec's wrap over clamp ensures the tail is secured and additional features ensure lower maintenance and better reliability.
