Centre roller bottom opening

Roller curtain, centre rolling, closing from the top down

Operation

The system is always divided into two canvases, so a 4-metre opening will require two 2-metre canvases. The system will always use a centre bar drive, controlled by a motor in rail. 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 (abo- ve the canvas). For large openings, the system comes with 1.5 inch tubular storm brackets, often used for freely supported spans that allow traffic underneath. An inner support is optional.

Construction

The system comes with a powerful 220-volt electric drive/ hand winch mechanism, which is directly connected to the centre bar. The covers at eit- her end of the rolling system come with a 60 cm wide hood made of galvanized materials. The winding tube is made of aluminium. The barn must be closed up for approx. 120 cm on one side to house the drive unit. Larger barns may benefit from controls in the centre,in which case, two metres have to be closed off for the drive system.
