Study of the force and travel required for your hatch::

Input please:

  • F1 = force / pressure of the electric cylinder
  • N = number of electric cylinder required
  • m = weight (in Kg) of the tailgate / of the object to be lifted, to be maneuvered
  • RH = longueur (en métres) du hayon / de l'objet à soulever, à manoeuvrer
  • x2 = distance (in meters) between the point of application of the electric actuator on the tailgate and the axis of rotation of the tailgate.

F1 = ( (m * RH) / (2 * N * x2) + 5 ) * 9.81

C = stroke of linear actuator:
C = 1/3 of RH (For opening at 90° )
Attention the calculation of the race (and of x2) is valid for 90% of the cases.
F1 = force / pressure of the electric cylinder:
Tolerance = +/- 40 Newtons
N = Number of actuators needed:
Stroke and force are calculated for each actuator(s)
y1 :
Caution - The dimension y1 must be 100 mm less than the stroke of the actuator
x1 :
The more the cylinder attachment is moved away from the axis of rotation of the hatch, the better the action of the linear actuator.
= ideal open the hatch at 80°
50 to 80 mm on average

This calculation tool is only valid for the type of layout above (see photo)
The calculation is reliable at around 90% - Our customers use this tool every day without encountering any problems
However, it is compulsory to check the result obtained with the help of a drawing (cylinder folded and cylinder extended).
This result proposal does not engage the responsibility of under any circumstances.
These calculations must be validated by a design office.
This tool is valid for an object with a centered center of gravity: uniform mass.

We remind you that the electric actuator is not a safety element.
To block a position, you must additionally use a mechanical blocking
