Hydraulic Drive Technology

Hydraulic Drive Technology is used in the SAF INTRA CD TRAK axle in the form of a hydraulic auxiliary drive that supports starting uphill or on uneven ground from the trailer when the traction of the tractor alone is no longer sufficient.  

The engine power of tractors has grown continuously in recent years. However, it is often not possible to convert this power into traction in challenging terrain or after unloading with only one drive axle.  

In order to bridge these difficult passages, the SAF TRAK starting aid is sufficient in many cases: It brings the drive into the trailer and uses the hydraulic power already available in the vehicle for an extra push. The SAF TRAK system consists of hydraulic wheel hub motors that are integrated into the SAF wheel end to save space. Drivers activate the auxiliary drive from the cockpit via the patented control system.  

Areas of application for the SAF TRAK auxiliary drive are tipper trailers, walking floor vehicles and applications in special vehicle construction.
