Hopper car for transportation of mineral fertilizers, model 19-9835-01

The railcar has been designed so as to minimize its own weight while achieving a higher load capacity, with the required durability and reliability ensured.

The hatches are of standard sizes and are installed on adapters, which can be quickly replaced in case either the hatch cover, the manhole or the adapter itself is damaged. The loading hatches have rubber seals to safely protect cargoes from precipitation.

Application of the coating based on vinyl copolymer provides proper protection of the body from aggressive influence of the transported freight.

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. The car’s body has eye bolts for it to be lifted and unloaded into the vessel from above at ports.

A system of independent two cylinder braking is applied for the hopper car, which provides more advantageous braking conditions, possesses higher efficiency and reliability in comparison with a traditional braking system. 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.

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.
