Some of the unique SRS/SVABO technical features

Hydrostactic transmission.
The driving system for rail transport is hydrostatic and consists of a hydraulic main pump, which is driven by a power take-off on the engine. The pump powers one or two hydraulic motors in the single rear axle or in the bogie, via a system of hoses.
Driving controls with speed monitoring
and "dead man's grip".
Driving controls for speed selection are installed in the driver's cab. the system can be equipped with a "dead man's grip", which means that the driver's thumb must rest on the top of the lever during driving. If the thumb is removed, and a pre-programmed interval is exceeced, a braking circuit cuts in and the vehicle is braked automatically.

Remote control cable/radio.
Track operation at working speed can be remote controlled by cable or ratio control. In addiction, sky lift or crane movements can be connected to  the same remote control unit.

Limitation of movement for sky lift, crane or other accessories.
The control system is designed to comply with stringent safety requirements. Various kinds of electrical and electromechanical switches can be installed, such as for limiting the slew angle of a sky lift or crane. This gives greater safety in work on a track where trains run on adjacent tracks.

Work operations on road or rail wheels, without outriggers.
The design allows work without outriggers, with the vehicle stationary on the ground or on track. The vehicle can also be driven forward during work on track and with the working platform raised to working height.

Vehicle braking systems.
Vehicle brake connectors front and rear, and an extra brake handle in the cab can be installed in the vehicle. The system is installed in accordance with applicable UIC standards and allows the vehicle to tow or push railway carriages. Drawbar pull varies between 1.2 ton and 7.2 ton, depending on vehicle weight.
