Without gas springs, today’s comfortoriented world would be less comfortable.
They provide safety in function and use.
Any pleasant properties that the end user
experiences, increases the value perception
of the respective product. Gas springs assist
with lifting, lowering, opening, and closing.
Gas springs dampen. They make technology
comfortable.
The LIFT-O-MAT with hydraulic damping
has an additional oil ll. The oil reduces the
speed as the end position is approached,
as soon as the piston leaves the gas and
enters the oil chamber. The use of patented Labyrinth pistons and the viscosity of
the oil determine the damping degree; the
oil amount used determines the damping
range.
The LIFT-O-MAT with dynamic damping is
a gas spring whose damping properties are
determined primarily through a groove in
the pressure cylinder. By reducing or increasing the groove cross-section, the speed
of motion can be varied over the entire
stroke.
Thus, the motion can be slowed down continuously, until it comes almost to a stop.
By varying the groove geometry, LIFT-O-MAT
can be adapted ideally to almost any application. Different compression and extensions characteristics can be realized as well
as dampened approaching of intermediate
positions.
A gas spring that uses additional coil
springs affects very high or very low spring
forces in the end positions, depending
on the installation mode. Based on the
application or requirements, rubber cushion
or coil springs are used to achieve a very
gentle end stop, in addition to the gas
spring effect. The coil spring length and
force can be adapted otimally to the
respective application.
The LIFT-O-MAT FR is a gas spring featuring
a special piston package with an integrated friction element, which – in addition
to force support – allows innitely variable
holding over the entire adjustment range.
Even weight uctuations between dened
limits, for example due to varying loads, can
be offset.
The HYDRO-LIFT features a valve in its
piston, which, in addition to user-optimized force support, allows innitely variable positioning in the compression range.
Controlled by a spring, the valve holds the
position until a dened pressure, which is
applied to the object by hand, opens the
valve. The extension force is specied in
such a manner that the gas spring does
not extend by itself. Depending on the
design of the HYDRO-LIFT, the hold function
can be active across the entire adjustment
range or in one or more partial ranges of
the application.
LIFT-O-MAT gas springs are non-locking
gas springs. They are used whenever components, such as doors, aps, and lids,
must be brought into a dened position.
LIFT-O-MAT controls the extension force
and damping action depending on the
function, thereby ensuring user-friendly
motion sequences.
Areas of application for LIFT-O-MAT are
doors and aps in machine and system
design, automotive construction, medical
technology, the furniture industry and other
industrial applications.

With the respective equipment, LIFT-O-MAT
with hydraulic damping can be customized to match the task to be performed.
LIFT-O-MAT provides comfortable damping
in the end stop range of doors or aps. Any
unchecked force application to hinges or
joints is effectively prevented; the motion
sequence is controlled and harmonious.

Following the laws of gravity, the advantages of this gas spring are used according
to the installation orientation: with the piston rod pointing down (extension-damped)
or the piston rod pointing up (compressiondamped).

LIFT-O-MAT FR allows free positioning of
the application, without the need to actuate
a lock or release mechanism.
For special applications with non-linear
force curves and for complex installation
positions with exacting opening characteristics.
LIFT-O-MAT FR provides for comfort in the
application and makes work easier for the
user.

Piston valve
Unlike the gas-lled version, the oil-lled
HYDRO-LIFT features are limited, rigid
locking in the compression direction, thereby
eliminating bounce.
Its application possibilities are wide
ranging; for example, wall cabinets in kitchen
applications or free-moving arms in medical
technology or in the electronics industry.
• Special forces in the end position range
A typical area of application of this
LIFT-O-MAT variation include doors and aps
in machine and system design, medical technology, the furniture industry, as well as other
industrial applications where the piston rod
swivels from top to bottom.
Additional advantages of the dynamic
LIFT-O-MAT:
• Innitely variable locking into
position
• End position locking
• Supple or rigid behavior in the
locked position
• Additional functions, such as
electric switches, STOP function,
locking, etc. can be integrated
Damping range
The LIFT-O-MAT with dynamic damping
works regardless of its orientation, thereby approaching any position comfortably,
without stressing hinges and joints.
Advantages and properties:
• Optimized weight compensation during
lifting, lowering, opening, and closing
• Broad selection of sizes and force
variants in the standard product line
• Flat spring characteristic curve; i.e., low
force increase, even at high forces and
large strokes
• Linear, progressive, or decreasing spring
characteristic curve
• Compact design for installation in small
spaces
• Large variety of end ttings for efcient
assembly
• Damped adjustment motion over

Miscellaneous end ttings
The INTER-STOP gas spring combines the
properties of the LIFT-O-MAT with dynamic
damping and the holding functions of the
HYDRO-LIFT, with the holding force working in
the extension direction. The stroke can be divided into one or more function areas.
For example, one function area might perform
the stopping or hold the application load in
any position, until a manual force is applied, for
example by hand.
Then there might be an additional range for
free extension with force support, which could
be stopped at a dened point.
The LIFT-O-MAT PTL is a gas spring with
an additional mechanical lock in the compressed position.
In addition to force support, the LIFT-O-MAT
gas spring with end position stop also
provides a safe mechanical lock of the
application in the extended position. As
a rule, two variations are available:
The KOMBI-LIFT is a combination of locking
and non-locking gas springs; that is, a
specied segment of the stroke can lock
during extension. It is locked by actuating
the lever on the piston rod. The function
areas can be arranged in any form over
the entire stroke.
It can be compressed independent of the
lever position, like a standard LIFT-O-MAT.
The LIFT-O-MAT INOX LINE is a gas
spring that is particularly corrosion
resistant due to the use of V4A steel
(see DIN EN 100 88-1).
Depending on the function as well as the
manufacture / assembly, STABILUS offers
a broad variety of end ttings and joints
made of plastic and metal, which can be
screwed on torsion-free. Here you will nd
a selection of popular end ttings.
Instead of a lever, all available actuation
systems of the BLOC-O-LIFT can be used
as well.
The LIFT-O-MAT INOX LINE is used in
corrosive environments, e.g., in sea air or
industrial exhaust gases. They provide very
good corrosion protection, even in acid or
alkaline environments.

The compression function of the gas spring is
the same as in a standard LIFT-O-MAT.

Similar to the ball point pen principle, the
lock can be released by a light push; the
gas spring then extends by itself.
In the gas spring with the stop on the outside, a support tube at the end of the piston
rod folds out automatically. To unlock, the
support tube is swiveled back into the central position.
Besides the force support function,
LIFT-O-MAT PTL features an end position stop, thereby eliminating the need for
additional xing elements. At the same
time, LIFT-O-MAT PTL is easy and comfortable to use.

The LIFT-O-MAT PTL is used especially in
furniture, e.g.: in recessed connector strips
in conference tables, bar compartments,
backrests of sofas, armrests, and head-rests
adjustment.
Areas of application are, among others,
service aps, hoods, car hoods, doors, roof
windows – wherever different opening
points are desired.
Press
(release button)
The lock of a gas spring with the lock on
the inside is comparable with the mechanics of a ball point pen. A light push on the
piston rod in the extended position locks it;
a quick movement in the extension direction releases the lock.
Support tube
LIFT-O-MAT Inox Line is non-magnetic.
The oils used as uids are biodegradable
and are classied as “no hazard to water”
in the water hazard class (WGK).
A typical area of application is the door
and ap limitation in utility vehicle cab
design.
Typical areas of application are environmental and water supply technology,
the food industry, plant construction,
shipbuilding, chemical industry, as well as
military technology.
Advantage:
A lock is always necessary or recommended, if the application needs to be protected against accidental adjustment or if the
application is subject to forces that exceed
the extension force of the spring. Such
forces could be wind or snow loads affecting the application.
