Stiefel - External Grate Drive System

Its main advantage is the possibility of immediately being able to replace a failing drive element whilst continuing normal operations. The externally applied force is transmitted through the grate side wall, to the grate step by a shaft. High quality materials are used to ensure the most effective compact drive unit. More available space outside the grate allows the implementation of various cylinder sizes. Therefore, more powerful drive cylinders can be installed instead of the standard ones a particular advantage for wide grates.
