ROLLING DOOR DRIVES
SI series rolling door drives have been specifically designed for unbalanced doors and have patented, integrated roll-down protection which prevents the door from falling down in any situation. The drives are mounted directly on the shaft. KE series rolling door drives have been specifically designed for unbalanced doors and have an interchangeable shaft. External roll-down protection (see the FG series under mechanical accessories) aims to prevent the door from falling down in any situation. The doors are driven by drives using sprockets and a chain. The SI and KE series have all functions and accessories needed for correct installation and use in accordance with product standard DIN EN 13241.
