CONSTRUCTION
The gas spring on one side is so mounted on a roll that its
position varies within a web guide depending on the
inclination of the flap. So fi be friend them during the whole
adjustment always in an optimal balance position. Thus, the
effort remains equally low for opening and closing.

throughout the entire stroke
| Steady hand force curve with a constant low | Steady hand force curve with a constant low

| Comfortable moving large and heavy flaps.| Comfortable moving large and heavy flaps.
The Optilift © is a special non-locking gas spring, which allows flaps to move with a uniform
and constant low effort.

Locking gas springs
The AL-KO LOCK locking gas springs offers a comfortable adjustment by The AL-KO LOCK locking gas springs offers a comfortable adjustment by The AL-KO LOCK locking gas springs offers a comfortable adjustment by
a specially selectable on the application characteristics and infinite locking
over the entire stroke.
By the operation of the integrated in the piston rod release pin is a specially
designed for the function of the piston valve, whereby the filling medium
can flow, and the sliding in and out of the piston rod allows opens.
After releasing the release pin, the piston separates the container chambers,
resulting in a blockage of the gas spring. Here, the blocking in accordance
with the request can be either resiliently, stiff or rigid to pressure to furnish
train.
It provides you with a wide range of locking gas spring solutions to choose
from which we can adapt to your specific application. We support you like

characterized by special corrosion and acid resistance. Thus, they are ideal for
your applications, which have correspondingly difficult environmental conditions.
In addition, stainless steel gas springs are largely non-magnetic. This will, among
other things results in measurement and medical hardly
fl uence. Other typical applications are unprotected outdoor areas,
different areas of the food industry, the chemical apparatus construction,
medical technology or the body.

If you have applications that are exposed to strong vibrations, possibly
even micro vibrations? Gas springs here are not the ideal solution, since
under such difficult conditions, the piston rod seal is very heavily used.
In this case, our spring element is the perfect solution for you.
The spring element is the combination of a damper and an external or
internal compression spring. The extension force is generated by the
mechanical spring during a damper
controlled moving speed ensured. The spring element is then tailored
to your applications. The result is an excellent kinematic solution that
guarantees a long service life even in severe vibration.
Another positive aspect is the temperature-independent extension force of
the spring element on the fully usable temperature range.
Tailored to your application solution with spring elements we
submit on request.

The force of gas springs is determined by the ratio of the internal gas pressure in
the cylinder and the cross-sectional area of the piston rod. By pushing the piston
rod, there is a compression of the gas volume in the cylinder and thereby an
increase in force exerted by the gas spring (progression). In this form, the values
F 3 to F 4 the insertion forces and the values F 2 to F 1 the Ausschubkräfte. As F 3 to F 4 the insertion forces and the values F 2 to F 1 the Ausschubkräfte.

The difference between the two force areas results from the friction

As preferred mounting position is with the piston rod to select down to
achieve the effectiveness of the hydraulic damper and to prevent dry
running of the seal.
