The first Soviet dump cars were developed based on American documentation at the Krasnoye Sormovo plant in 1931. The following year, the cars began to be produced in series. The first of them had a carrying capacity of 40 tons. They were supplied for the construction of the Dnieper Hydroelectric Station and Magnitka, the Bakal mines and other large-scale construction projects.

In 1943–1944 dump cars were built by the Kalinin plant, and from 1946 — by the Kaliningrad plant, which later became the main base for the construction of dump cars. 40-ton cars were also produced immediately after the war in Germany at the Görlitz plant. In 1947 the Kaliningrad plant began building dump cars with a load capacity of 50 tons of the BC-50 type. The modified design was designated 3BC-50 (the third model, BC — dump car, 50 tons).

Such cars were built in Czechoslovakia at the Vagonka Tatra Studenka plant in 1949–1951. This plant later produced six-axle dump cars. Most Soviet citizens knew it for its production of ACh-2 railcars in 1984–1990.

The dump car body tilted during unloading, and the sides folded back when the body tilted. The sides could be folded up or down depending on the design of the car. After unloading, the body lowered to its original position under its own weight. One of the important design features of these cars was the multi-layer floor, which cushioned the weight of the falling load. Some dump cars could withstand the weight of falling boulders weighing up to 2 tons.

Dump car or dumpster. The name comes from the English words: "dump" - to dump, "car" - car.

The development of industry and new industrial constructions required cars with a large carrying capacity. They were needed for the transportation and automated unloading of overburden, coal, ore, soil, sand, crushed stone and the like.
