FIELD: load lifting facilities; bridge cranes with shock absorbers. SUBSTANCE: bridge crane has main and end beams. End beams are furnished with shock absorbers. Novelty is provision of thrust beams and mating load platforms. Thrust beams are secured on main beam in parallel with end beams. Load platforms are arranged on brackets of crane structure columns. Clearance left between thrust beams and load platforms closes in case of overloading. Thrust beams are made for adjusting the clearance in vertical by means of hydraulic jacks. EFFECT: reduced materials usage, increased service life of crane structures and end beams of bridge cranes. 2 cl, 1 dwg
