7 General concept
7.1 Operation
Doors that are operated with gravitational force, using ballast consisting of little bags with very small
steel balls in the bottom part of the door.
Flexible, self-repairing door. The door opens by winding the curtain around a drum driven by a
reduction motor. The door closes through gravitational force, in other words, the curtains own weight
and ballast. The flexible ballast is located at the bottom of the curtain and lets the door close whilst
the reduction motor unwinds the curtain.
In 'automatic' mode (standard), the door is opened with a pushbutton or by an automatic command.
Closure of the door is achieved with an adjustable timer.
This timer cycle is restarted every time someone interrupts the infrared obstruction detector or when
the detector that monitors the correct unwinding of the curtain (situated at the top of the guides) is
activated.
7.2 Metal frame
This is produced in sections of galvanised or stainless steel (see options). This frame is fixed against
construction opening.
7.3 Side guides.
Inside the metal frame there are fixed guides.
These are made of polyethylene, so that they slide optimally over the entire length of the frame. The
thickness of the side guides is adjusted to the operational environment. Two moveable reintroduction
blocks at the top ensure that the door repairs itself.
7.4 Lubrication system
The guides end at the top with reintroduction blocks that are equipped with an insert consisting of a
polyamide (PA) holder and a special piece of felt saturated with 1.6 cc of a lubrication agent.
7.5 Curtain.
The curtain consists of flexible material, made of a very durable polyester fabric covered with PVC,
and is available in various colours. It has a flexible ballast consisting of very small steel balls in the
bottom part of the door. The curtain is held by the guides and retaining straps mounted on the sides.
The door curtain can be fitted with windows made of flexible PVC.
