Reason for the switch

The two MINI 01 Actuators handle the cab. Previously, pneumatic cylinders were used. The MINI Actuators are better suited because they provide a more consistent lifting motion and are additionally equipped with a force-dependent end limit switch.

Through a spring assembly, a defined force can be combined via the spring constant. When the spring assembly is compressed, a limit switch sends back the signal. Advantage: The limit switch can also be adjusted in position, allowing the customer to precisely adjust their force point.

You can choose between 24V, 230V, and 400V.

Yes, the use of stainless steel materials is a common practice for environments with aggressive media.

Yes, Screw Jacks and MINI Cylinders can be used within certain limits for ATEX zones as well.

Check the power supply. For 24V DC drives, fluctuating loads can also cause varying speeds. Additionally, ensure that potentiometers, encoders, and brakes are correctly controlled.

No, the MINI Cylinders are complete systems and cannot be expanded with other motors.

For the spindle end, the standard range offers options including threaded end, articulated head, ball joint head, flange plate, bearing flange plate, and pin. You can find corresponding dimensions in the General Catalog 2023 (grob-antriebstechnik.de)
