Dump car BC-66
Dumpcar is designed for transportation and mechanized unloading of bulk and lumpy cargo: loose, semi-rock and rock, iron, nickel, copper, manganese, apatite ore, coal; sand, gravel and other building materials.
The design of the car ensures the transportation of bulk materials with a loosened density of 1.7-2.0 t/m3 on the main railways of 1520 mm gauge and allows a block weighing no more than 2 tons to fall from a height of 2 meters onto a bedding of at least 300 mm . The car is equipped with stops from shifting in the longitudinal direction of the upper frame relative to the lower one.
