The drive unit consists of an electric motor located inside a double-sided gear which transmits the torque to all gears simultaneously through steel pipes. The whole thing is discreetly hidden under a fixed hood and covered from the bottom with a fabric.
The fabric connected to the beams moves along the guide by means of rolling carriages pulled by a toothed belt. A seal placed in the guide profile prevents rainwater from spreading over the sides of the pergola.
Wind beams support the fabric, preventing it from hanging too much under the load of wind and water. Additionally, at intervals of about 120 cm in the direction of the overhang into the fabric, a keder profile connected to the beam is heated in order to eliminate winding of the fabric.
Optionally, it is possible to install LED spotlights with a warm color (40ln, 1w, 12V DC) on selected fabric beams. The power cord is hidden in a heated pocket along the edge of the fabric.
Rainwater runs down the fabric towards the gutter where it is collected and discharged to the posts. The gutter is a structural node that integrates the guides with the columns.
The water is drained from the gutter through all the poles and flows outside through the drain hole located at the front of the pergola.
