The smallest models, the Hyrax 125 and 175, have one eccentric. The models from the Hyrax 250 onwards have two eccentrics, each driven by a hydromotor. The absence of a gear transmission simplifies maintenance.

Safety Belt System
Rubber elements in the traction head neutralize vibrations between the casing and the excavator, preventing overload. To prevent accidents in case the rubber elements unexpectedly tear due to wear, Dehaco has developed the Safety Belt System. This safety belt ensures that the vibration casing can never become detached from the traction head. The Hyrax vibration units therefore meet the strictest safety standards.
If you want to guarantee the safety and reliability of your hydraulic equipment, it is possible to have Dehaco inspect your vibration blocks periodically. Our own 24/7 service department can perform minor repairs on location; larger repairs can be carried out in our own workshop.
The smallest vibrating blocks in the Hyrax series are equipped with a single hydraulically driven eccentric. They are extra safe thanks to the specially developed 'Intelligent Single Power System'.
ISP System®
The ISP System® ensures the safe operation of the vibrating block:
Equipped with an overpressure safety device (bar)
Equipped with a volume control (l/min)
Equipped with a run-out function to protect the motor.
Equipped with connection protection for the supply and return lines.
