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.

Crane bk-1000 was pierced by nm mneneneo ussr (Zuevsky Overen) Currently replaced by a modification of BK-1000B.

The crane gantry is a three-bearing cylindrical structure supported by two-wheeled balancing carriages mounted on double-strand rail crane tracks. The design of the portal consists of a cylinder, a support diaphragm and three support legs with ballast plates fixed to them. A thrust bearing and a pinion wheel of the rotation mechanism are placed on the diaphragm.

Modifications of tower crane BK-1000:BK-1000A has the following changes: a 10 m long jib was used (instead of 3 m), with a lifting capacity of 9 tons; the upper section of the boom has been reinforced.

BK-1000B has the following changes: the carrying capacity of the main and auxiliary hooks has been increased to 63 and 18 tons, respectively.

BK-1000V has a boom shortened to 24.78 m, due to this, the carrying capacity has been increased to 100 tons. The auxiliary lifting mechanism has been removed. The reeving of cargo ropes has been changed.
