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.

A system of independent two-cylinder braking provides more advantageous braking conditions, possesses higher efficiency and reliability in comparison with a traditional braking scheme. 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.

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.

Hatches in standard sizes are mounted on adaptors, which can be quickly replaced in case of the damage of cover, throat, or adaptor itself. Five loading hatches ensure that the goods are evenly distributed inside a car. The use of rubber seals allows hatches to protect effectively the transported goods against adverse effects of precipitation.

The design used helps reduce the car weight and increase its pay-load capacity while ensuring the required structural strength and reliability, as well as lower the center of gravity.

In order to prevent unauthorized access to the goods being carried, locking mechanisms of loading-unloading hatches accommodate original and effective interlocking device. Two seal-lock devices instead of the four used in counterparts bring about significant cost and time savings. In addition to that, sealing and verification of seals are carried out without having to climb up a wagon.
