Mobile crane comprises bearing frame with rotary jib lifter and towing coupler with towed trailer coupled therewith in working conditions. Sais trailer is coupled with running frame by fixation mechanism furnished with the drive and link between connected components. Then, bracing jacks, outriggers, are set to working position to lift the crane along with trailer. Running frame and towed carriage propulsive wheels with counterweight are lifted above the track to make crane and trailer weight counteract the weight moment.
