Inflatable Thrustors
Pressing- Lifting - Gripping - Guiding - Dampening - Handling...
Mustpress lifting bags are adapted to any industrial equipment and usually replace hydraulic and mechanical jacks. They are made of elastomer coated fabrics and supprt high inflation pressure (up to 100 bars).
Available in different shapes and dimensions (square, round, rectangular, toric). In order to increase their thrust, they are available with 2 or 3 stages.
Mustpress is inflated with air, oil or water.

The LUKAS pulling cylinder HP 30/Z 200 is compact and very light as the cylinder body is made of high-strength light metal alloy and offers a long stroke of 200 mm. For high lateral load tolerance the cylinder is equipped with a wide guiding ring which serves also as a fully loadable stroke limitation. When the pulling job is finished the piston is spring-retracted to its initial (extended) position.
