Product

In project SELF PROP RAIL, the consortium aims to bring a new, innovative self-propelled bulk carriage to the market that does not need the locomotive for shuffling/moving during the process of cargo unloading.

The self-propelled bulk carriage is a resource efficient way of (re)construction of railways. The carriage saves energy, human resources and shortens the time of transportation and unloading. It is cost and time efficient, it enables point-to-point transportation, and there is no need for cost-intensive cargo manipulation machinery for freight handling or time-intensive coupling and reloading processes.

The physical location of this project will be in Railway Carriages Factory Cakovec (RZV) in Croatia. The business is located on one of the most important railway routes in Europe which is an advantage for marketing since the accessibility is increased. RZV is a medium-sized company with a production capacity of 100 units/year. It is possible to raise capacity to 500 units/year via a production cluster.

One of the innovative parts of this carriage is the development of a new construction opening and the unloading of cargo on 3 sides (i.e. a ‘3-side dump’). The carriage consists of 2 cargo crates with the possibility of side and frontal lifting. 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 sides that is common in existing bulk carriages for railway construction.

Compared to existing carriages with inadequate pneumatic system, the self-propelled hydraulic carriage has a larger cargo capacity, faster unloading using the ‘tipping’, i.e. tilting sideways, existence of the roof which enables transport of hygroscopic materials (grains, fertilizers, ore), ability to transport fine grit without spillage, and quieter operation (there are no huge air high-pressure tanks on the carriage any longer).
