Bk-1000-tower self-propelled (rail-mounted) crane 8-anz grupfter (load moment 1000 t). A structure prepared for assembly with a mass of assembled elements of 63 tons. The first BK-1000 cranes required a lifting capacity of 50 tons on the main lift and have been produced since 1961. In addition to the basic model, the crane has eight modifications (-A, -B, -B, -D, -P, -40, -48, -60), These are not technical specifications and other design elements.
