Solid-bottom gondola, model 12-6877 (articulated)

Unloading with tandem dumpers used at large Russian ports as well as unloading with the modern VRS-125, VRS-134 models.

Car design allowing efficient heating in defrosters to unload materials that stuck together due to freezing conditions. The car can be cleaned from cargo remains using 4 cleaning hatches located in each car section.

Better resistance to damage of the car body when being unloaded owing to a strengthened top chord cross-section and posts having varied cross-sections and spacing distances.

The braking system with individual braking at each bogie is equipped with modern braking devices having an overhaul life of not less than eight years, fittings for threadless connection of brake lines and wear-resistant bushings made of composite molding material based on formaldehyde resins.

The automatic coupler is equipped with lower limit stops and a modern class T2 shock absorbing device, which reduces longitudinal forces acting on the car.

The car is installed on bogies with a 25 t axle load. Bogies with an integrated brake system increase operation safety and maintenance interval, and reduce the general lifecycle costs of the product.

The articulated car is equipped with the SAC-1 articulated connector, which joins the two sections of the car and ensures a smooth passage round track curves, including those with small radii.

Description

The 12-6877 six-axle articulated-type gondola car is unrivaled at the CIS market; it is designed for efficient transportation of cargoes in a wide range of densities.

The gondola car is unique in that it boasts an increased body volume and enhanced payload compared with other models available in the market. These parameters were attained owing to the fact that the articulated gondola car is fitted with the SAC-1 articulated connector that joins the two sections¹ of the car and ensures flawless passing through track curves including those with small radii.

The 12-6877 gondola car is compatible with public and private infrastructure and can be sent over a classification hump with no limitations. The design of the car allows unloading with tandem car dumpers used at large Russian ports as well as unloading with the modern VRS-125, VRS-134 models.

Extended service lives and maintenance intervals provide significant savings on life-cycle costs.

Using this car type to form trains will allow reducing the number of cars required for the transportation and increase the weight norm staying within the standard train length which raises transportation efficiency and boosts the railway network throughput capacity by up to 40%.

Producer: Tikhvin Freight Car Building Plant, JSC.
