Hydrema - Model 912GS -Rail Dump Truck
Moving gravel and construction materials on tracks has never been easier, than with the Hydrema 912GS Rail dump truck. Capable of working both in high and low rail mode, while delivering the material in a 180-degree area.
Flexible rail system
- Detachable rail modules
The rail modules are mounted on a bolt-on system with quick couplings for the hydraulics. Hereby they can easily be de-mounted when not used for work on the rail.
Big rail wheels (with a diameter 450 mm at the front and 550 mm at the rear) ensure the position and driving stability of the dump truck on the tracks, even at high speeds.
Individual disk brakes are mounted in the hub of the rail wheels, so that both the service and parking brakes work directly on the rail wheels.
- “High rail” mode
The 912GS can work in both high and low rail mode. In high rail mode, the tires are lifted 125 mm from the tracks. Hereby damage to track sensors and shifters are avoided as the rubber wheels are lifted entirely off the rail track.
A roller is pressed against the rear rubber tires, transferring the traction directly to the rail wheels.
- ”Low rail” mode
In the low rail working mode, the rubber tires run directly onto the rail tracks, which maximizes the traction.
The position of the rail wheels is controlled by sensors, securing the correct load both on the rubber wheels and the rail wheels.

Integrated cameras
In addition to the rearview camera, two cameras are mounted in the front and rear end below the dump truck to monitor the rail wheels, giving the operator the perfect conditions to position the rail modules correctly on the rail tracks.
- Automatic articulation lock
For safety reasons, the 912GS Rail dump truck has an automatic, hydraulic lock for the articulated steering equipped as standard. In this way, the front and rear chassis are locked together to keep the truck stiff and minimize the derailing risk. Engaging and disengaging the lock is carried out conveniently from the driver`s seat.
When on the railroad tracks, the pivot point`s oscillation is automatically locked, to have maximum stability.
- Emergency operation
In the event of an engine failure, the hydraulic functions can be operated using the emergency pump.
Furthermore, the brakes can manually be released, if needed.
