LIBRUM is an industrial door for large dimensions with unilateral or bilateral opening with a manual or motorized drive. Storage at 90°.
Folding door ideal for large dimensions (up to 10 meters in height) and for intensive use. It is characterized by the sliding system consisting of a particularly structured and engineered upper rail of 150 or 250 mm. The rail is equipped with derailing device with directional curve and sturdy trolleys, sized according to the number and width of the door leaves.
The doors can be motorized through the installation of 1 or 2 gear motors (single-phase or three-phase) with chain drive, equipped with manual emergency release.
The bottom rail, in galvanized steel, is recessed in the floor. Rollers with adjustable and easy-to-replace ball bearings slide on the bottom rail. The bottom rail can be made with profiles suitable for the passage of exceptional loads.
NOTE: the SUPERTHERMIC LIBRUM industrial door is also available in the evolved ISOMAX thermal cut version with height limitations ( see ›› )
