Hopper car for transportation of mineral fertilizers, model 19-9549-03

Innovative bogie improves dynamic characteristics of the freight car, enhances safety of its operational use, increases between-repairs run and decreases life cycle costs of the product as a whole.

Brake system is completed with modern brake devices which between repairs term is not less than 4 years, fittings for the threadless connection of brake pipelines, wear-resistant plugs made of composite pressing material (CPM) on the basis of formaldehyde resins, providing a run resource not less than 1 mln km. A system of independent two cylinder braking is applied for the hopper car of model 19-9549-03, which provides more advantageous braking conditions, possesses higher efficiency and reliability in comparison with a traditional braking system.

The coupler pulling face is equipped with a modern draft gear of T1 class, which reduces the level of longitudinal forces, acting on the freight car. There is also an improved uncoupling drive on the freight car, preventing the coupler pulling face from falling on the track in case of breakage in an emergency.

Gates of standard sizes are installed on connectors that can be promptly replaced in case of cover, collar or connector damage. Five loading hatches provide uniform distribution of freight in the freight car. Loading hatches properly protect grain and other transported freight from adverse effects of precipitation thanks to the application of rubber seals.

The applied schematic construction lowers the freight car gravity center, decreases the freight car weight and increases its load-carrying capacity, ensuring the required structural strength and reliability of the freight car construction design.

Unique and effective blocking units have been applied in loading hatches and unloading gates locking mechanisms in order to prevent unauthorized access to the transported freight. Two locking and sealing devices instead of four, used in counterparts, significantly reduce costs and save time. In addition, there is no need to ascend the freight car while applying seals and inspecting seals integrity afterwards.
