Range Of Application For Roof Windows With Drive Holder - GEZE E740 Syncro System- Und Montageanleitung

4.3 Range of application for roof windows
with drive holder roof window
Casement area max. 3 m² for windows with 2 Syncro drives
Max. casement weight: For calculation see below.
Ü = Overlap height from 0 to 20 mm
(spacer on site possible)
Required space
on the casement
a = Casement width max. 2400 mm
Required space for mounting two
E740 Syncro on frames min. 1000 mm
Equation for calculating the opening and closing force for
light domes or horizontal windows with two drives E 740 Syncro
F = Drive force, required to open: max. 500 N
P = Casement weight [in N]
Example:
P = 60 kg = approx. 600 N
F = 600 N x 0.68 = 408 N
at overlap height
Ü = 0 [mm]
* Guide values, mounting can vary
depending on window type
F = 0.68 x P
Fmax. = 500 N
Casement height Fh to flap hinge centre
at overlap height
Ü = 20 [mm]
