FIELD: construction.
SUBSTANCE: invention relates to cranes with longitudinal beams. Crane comprises at least one horizontal crane beam of framed structure with the upper and the lower guides, on which the crane trolley with a hoisting mechanism is installed able to move. Hoisting crane on one or both ends of the crane beam is equipped with a movable assembly-adapter containing a connection surface for attachment to the travel mechanism. Adapter is moved both along the length of the beam, and, if required, up and down, right, left or turned at a certain angle around the longitudinal axis of the beam. Then adapter in the final position is welded to the crane beam, after which the adapters connection surfaces are connected with the crane travel mechanisms.
EFFECT: compensation of certain tolerances in length and other dimensions of the beam during its manufacture is achieved, as well as simplification of the crane beam design.
