In cases of power failure, roller shutters can be operated manually by two options. The basic
manual operation equipment includes:
Crank manual (basic equipment)
Chain hoist manual (optional equipment, after customer’s request)
In order to deal with the stress of the device by strong winds, it is envisaged to place a calculated
number of anchors, which are fixed and held firmly to the edges of the profile of the curtain.
The anchor consists of a "bifurcated" plate in which two polyamide wheels are fitted. The smooth
rotation of the wheels is achieved by means of closed-type bearing rings (roller bearings), and evolves
into a suitably shaped cavity of the vertical guide (Figure 4). In this way it is possible to anchor the curtain
on the guides eliminating friction, damages and noise.
The guide has longitudinal aluminum profiles of a suitable cross-section, the fittings of which are
fitted with EPDM rubber and PVC profiles respectively, each performing a different task:
PVC profile has a curved cross-section, so that when it comes into contact with the curtain,
smooth and silent sliding is achieved as the coefficient of friction is significantly reduced.
EPDM tire acts as a barrier for foreign particles that can enter the opening as well as a shock
absorber caused by the movement of the curtain, which can cause noise.
