Preheating to operating temperature

Preheating to operating temperature

The gearbox oil is preheated and flows through the standing gearbox to the exciter block so offering improved lubrication. This minimizes wear and tear and extends the service life.

Continuous cooling

Continuous cooling

The cooling circuit is connected to the carrier machine and continues to cool even when the vibrator is not in use, so ensuring consistent cooling of the vibrator.

Purposeful energy focus

Purposeful energy focus

Thanks to the symmetrical suspension and low wear linear guiding of the vibrator, the swing movements run parallel to the axis which reduces loss of energy.

Large dimensioned main bearings

Large dimensioned main bearings

The bearings of the eccentrics’ shaft are largely dimensioned and so designed for a long service life.

Obstacle recognition

Obstacle recognition

An improvement for slurry wall application is the obstacle recognition, which enables the timely detection of obstacles in the soil. This protects both the attachment and the basic machine. more

Continuous amplitude adjustment

Continuous amplitude adjustment

The patented external amplitude adjustment is robust in design, maintenance-free and allows for continuous regulation of the eccentrics.

Integrated control system
