FIELD: transport.
SUBSTANCE: invention relates to railroad transport and can be used for replacement of freight car centre plates in the conditions of depot repair. Car centre plate remover with work body source represents a pneumohydraulic booster with controlled valve of charging and hydraulic accumulator communicated with centralised pneumatic line communicated, in its turn, with pneumohydraulic booster rod end via pneumatic control valve. Aforesaid controlled valve of charging is arranged between hydraulic accumulator outlet and pneumohydraulic booster hydraulic chamber. Rod chamber of the latter is communicated with uncoupling hydraulic cylinder piston end. Rod end of the latter is communicated with pneumohydraulic booster hydraulic chamber via high-pressure pipeline.
EFFECT: higher efficiency of dismantling of car centre plates.
