Hopper car for transportation of grain, model 19-9549-02

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

Material consumption of the design has been significantly reduced and the problem of the increase in the roof and loading hatches corrosion resistance has been successfully solved thanks to the application of aluminum alloy. Mounting of the aluminum roof onto the steel body has been implemented with the application of modern hi-tech bolts with bolt collars (HUCK-bolts).

Model 19-9549-02 has an optimum ratio of inclination angles of bins unloading walls and end walls for the complete emptying of the freight car.

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 car while applying seals and inspecting seals integrity afterwards.

Stamp-welded hatches and gates possess increased rigidity and durability; prevent cover corners from being pressed out from collars. A molded rubber strip of a continuous section serves as a sealing and therefore the sealing wear resistance and tightness of connection between the discharge cover and collar are significantly increased.

Brake system is completed with modern brake devices which between repairs term is not less than 8 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 19-9549-02, which provides more advantageous braking conditions, possesses higher efficiency and reliability in comparison with a traditional braking system.

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.

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.
