Lift cushions
Hebekissen
Hefkussens
A lift cushion is, through clamping strips, a hermetically sealed hose
part with a connection for compressed air. After the hose part
has been filled with compressed air, it will change into a rounded
form. Lift cushions can be connected both horizontally as well as
vertically. Look at the dimensions for a diversity of dimensions and
calculations.
Ein Hebekissen ist, mittels Klemmplatten, ein hermetisch
verschlossener Schlauchteil mit einem Pressluftanschluss. Nachdem
der Schlauchteil mit Pressluft gefüllt wurde, nimmt es eine runde
Form an. Hebekissen können sowohl horizontal als auch vertikal
angeschlossen werden. Sehen Sie sich unter Maße die Vielfalt an
Maßen und Berechnungen an.
Een hefkussen is, door middel van klemstrips, een hermetisch
gesloten slangdeel met een aansluiting voor perslucht. Nadat het
slangdeel gevuld is met perslucht neemt deze een ronde vorm
aan. Hefkussens kunnen zowel horizontaal als vertikaal worden
aangesloten. Kijk bij afmetingen voor de diversiteit aan afmetingen
en berekeningen.
Lift cushions can transfer high forces in a constant manner and are
due to simple technique very reliable .
Lift cushions can be used for various purposes and the advantages
of a lift cushion in respect to a cylinder are enormous.

FLOOR SPECIFICATIONS
The floor is an integral part of the aircushion transport system.
The right condition for the correct functioning of aircushion systems is offered by a NON POROUS, SMOOTH
and LEVEL floor. Appropriate is a mechanically trowelled floor with a smooth even finish. The surface can be
impregnated to prevent dust, porosity and reduce wear. The joints can be filled using a silicone kit or plastic
tape.
SMOOTH
floors ensure the air film to be as thin as possible. The air film determines the air consumption. The
aircushion principle is based on the escape of excess air between the membrane and the floor. This air
film allows the load to float almost without friction.
NON POROUS
floors are necessary to enable
the aircushions to be inflated
with air and keep the loss of air
to a minimum.
LEVEL
floors prevent the load from
drifting away, this will happen with a sloping floor
JOINTS
Expansion joints can be filled with a Urethane or Silicone kit. The top shape of the filler should be
rounded and convex, not concave (ca. 0,2 of the width).
FLOOR CLASSIFICATION
To provide an example of the influence of the operating surface on air consumption we made a comparison
between several surfaces. These have been given a suitable rating: 1 = optimum, 10 = unacceptable
1. Glass
1
2. Epoxy floor
1– 2
3. Galvanized steel plate
1– 2
4. Hardboard, plastic, linoleum, spray painted chipboard 1 – 2
5. Concrete floor, impregnated
2
6. Concrete floor, not treated
3– 3
7. Concrete floor, not treated, new to 3 months
5– 6
8. Concrete, manually trowelled (not acceptable)
8 – 10
9. Asphalt (not acceptable)
10 – 15
OLD FLOORS.
Old floors can be suitable if they are smooth and there are no dents or cracks, otherwise improvement is
necessary. For minimum costs paint or an impregnation can be applied. When, however, a new topcoat is
necessary, a good attaching to the original surface is very important when applying aircushion transport.
NEW FLOORS.
New floors are very appropriate if they are comparable to the following standard:
BSI-8204 Part 2 (UK), ASTM-E1155 M-87 (USA) or similar.

POROUS FLOORS
On a porous floor the loss of air may be so high, that
insufficient air is supplied to create a satisfactory air film. The
average concrete floor without special treatment is to a
certain degree porous. Normally, painting or sealing a
concrete floor is sufficient treatment to overcome porosity.
UNEVEN FLOORS
Aircushions can, due to their elasticity, give limited
adaptation to unevenness in the floor up to a maximum of
2 % of the aircushion diameter. Large fluctuations can work
like a slope. An object on aircushions will, because of the
low friction, drift away on a sloping floor. The extra power,
necessary to push the load “uphill” again, will be:
“slope percentage x weight i.e. 1% x 10.000 kg = (100 kg) 1.000 N.
INCIDENTAL TRANSPORT
A floor can always be made suitable for aircushion transport by covering it with f.i. a metal or plastic sheet.
Joints and cracks can be covered or taped. Thresholds or steps can be overcome by using the tilt possibility
of the aircushions and some filling material.
under the following conditions
an AIRCUSHION TRANSPORT SYSTEM functions
ALWAYS and EVERYWHERE
1 – sufficient air supply
2 – aircushions are parallel to the floor
3 – a suitable floor
4 – no over/under loading. Aircushions from 6.000 kg up, need a minimum loading of ca. 20 %
