Machine made on special order in the experimental shop KrAZ immediately after the accident on April 26, 1986 at the Chernobyl Nuclear power Plant. In the shortest possible time on the basis of the production model KrAZ-256B 18 copies were made. Since the vehicles had to operate directly near the accident site and remove radioactive earth, dust and debris from the explosion site of the station's 4th power unit, the standard cabin was completely replaced by a single lead capsule, which had one front window and provided protection to the driver from the strongest external radiation
