6.1.10 Calculating forces/stroke
This calculation is only valid for wall windows mounted
vertically. A detailed calculation must be made for all other
mounting positions, which we will be pleased to assist you
with.
F := the force of the actuator [N]
S := the stroke of the actuator [mm]
H := the height of the window sash [mm]
W := the weight of the window sash [kg]
Required actuator force for the specified stroke:
F = (W / 2) x (S / H) x 10
= (W x S x 5) / H
Maximum possible actuator stroke for the specified force:
S = (2 x F x H) / (W x 10)
= (F x H) / (W x 5)
