Jewers Doors supplied and installed a set of Osprey (OSP-E) sliding folding doors for an opening 20 metres wide x 6 metres high. The top hung Osprey door is electrically operated and has an integrated wicket door incorporated into one of the panels for pedestrian access. Each door half is driven by a powerful inverter-controlled drive unit which moves each of the 10 leaves effortlessly across the opening and then folds them into a 1m² footprint behind the opening. This large door is installed with several sensors providing an invisible zone around the door leaves to prevent the doors from impacting a person or aircraft during opening and closing.
