Highly Flexible Cable for Energy Chain Systems
All chain systems (e.g. container cranes, stacking cranes, indoor cranes,material handling equipment). Especially in outdoor application and at long travel distances, high speed travels and high expectations (such as long lifetime, reliability, abrasion resistance, etc.) to the cable.
