Overspeed Governors

Research for innovative solutions and rigid control of product quality are key features of Wittur Safeties. 
Wittur overspeed governors can cover a broad range of rated loads and speeds and can be applied both to machine roomless and traditional installations. Our overspeed governors can be engaged at any point along perimeter of pulley and assure high life time due to limited pulley wear.
