Equation for calculating opening and closing force: F = p x stroke x 0.54 b Example for E820 in individual operation: P = 25 kg = approx. 250 N Stroke = 400 mm b = 1000 mm F = 250 x 400 x F max. = 250 N per drive F = 54 N Key F Opening and closing force required (N) P Casement weight (kg) Stroke Casement path/drive stroke (mm) b Casement height (mm) windows window Stroke F Example for two drives E820 Syncro: P = 95 kg = approx. 950 N Stroke = 400 mm b = 800 mm F = 950 x 400 x F = 257 N b F P Stroke P b Casement panel weight: max. 30 kg/m 2 (drive cannot be swivelled) max. 40 kg/m 2 (drive can be swivelled) Max. pushing and pulling force depends on the drive stroke (see force-path diagram).
