Centre bar bottom roller

Roller curtain with top bar drive, closing from the bottom up

Operation

Turning the top bar, which is directly connected to a powerful 220 or 380- volt electric drive, will move the aluminium tube with the canvas attached up or down. Using a right-angle transmission, the motor is reconnected to the bottom roller tube. The curtain has a welded string on either side, attached to a pull-up bar at the top and a winding tube at the bottom. For large openings, the system comes with support/bird screen as standard to prevent the canvas from being blown inside by the wind and causing damage. An inner support is optional.

Construction

The system comes with a powerful 220 or 380-volt electric drive, which is directly connected to the top bar and the bottom drive. The covers at either end of the rolling system come with a 60 cm wide hood made of galvanized material. The pull-up bar and a winding tube are made of aluminium; the traction wire is attached to the bar using a special clamp. The barn must be closed up for approx. 120 cm on one side to house the drive unit.
