Power and Free Conveyors do not have to stop the entire line for material to be stopped or diverted. As a result, they are a perfect solutions for industries with complicated lines. A Power and Free system allows for great flexibility in production because it can integrate many features such as: variable speed chains, inversions, elevations changes, and accumulation areas for work in progress. In addition, a power and free system can be designed to operate in corrosive and non-corrosive environments.
Power & Free systems used in a production facility reduces the need for increased material handling expenses. In other words, one system is capable of doing everything. The system provides a constant supply of material to each processing station. In addition, the system also sustains several different production lines. In conclusion, the constant supply of material increases productivity and that is a key principle of Lean Manufacturing.
