The self-propelled bulk carriage is a resource efficient way of (re)constructing railways.
"Self-propelled" means complete autonomy of action and better distribution of the locomotive fleet, which ensures enhanced resource efficiency. The carriage is an independent self-propelled unit with a completely integrated system for the hydraulic manipulation of boxes and carriages. The carriage consists of 2 cargo crates with the possibility of side and frontal lifting via its hydraulic systems. The unloading is controlled, enables full load ejection as well as dosing and partial unloading of cargo at points along routes. There is no need for manual unloading of cargo, use of other machinery for unloading or use of physical force when opening the doors and side panels, which is common in existing bulk carriages for railway construction. Handling is completely automatized with a simplified operating console that is adjusted to the user. It needs only 1 person to operate it.
The self-propelled working mode is enabled by an ‘extra' neutral wheel which goes down on tracks only in the moments when it needs to move down the rail (on switching gauges, industrial gauges, and rail tracks for (re)construction). This ensures greater safety because there are no lateral and axial forces on the existing rolling wheels. The self-propelled bulk carriage uses a small mobile hydraulic generator, driven by an industrial diesel motor which satisfies EPA Tier 3/Stage IIIA emissions regulations.
