ACTUATOR FORCE (F) FOR VERTICAL WINDOWS

Force calculation example
F = (WINDOW LEAF WEIGHT /2) X (ACTUATOR STROKE / WINDOW LEAF HEIGHT)
WINDOW LEAF WEGHT (P) = 100 kg
ACTUATOR STROKE (C) = 250 mm
WINDOW LEAF HEIGHT (H) = 1000 mm
THE REQUIRED FORCE (F) IS:
F= (P:2)X(C:H)
F= (100 : 2) X (250 : 1000) =
12.5 kg (125 N)

ACTUATOR FORCE (F) FOR HORIZONTAL WINDOWS

Force calculation example
F = WINDOW LEAF WEIGHT / 2
WINDOW LEAF WEIGTH (P) = 100 kg
THE REQUIRED FORCE (F) IS:
F= P: 2
F= 100 : 2 = 50 kg (500 N)
