Freight car bogie disassembly and assembly station

The station is designed for breaking down freight car bogies into their components before inspection and repair, and for reassembling them afterwards. It performs bolster lifting and holding, removal of spring sets and friction wedges, lifting of the side frames off the axle boxes, side frame spreading and wheelset roll-out. The equipment is built for two-axle three-piece bogies and is installed in the bogie section of a car repair depot.

The bogie is rolled onto the station along the rail track and locked by stops. A hydraulic lifter with a cross beam raises the bolster and holds it at the set height, after which the spring sets are removed by hand or with a puller. The side frames are raised off the axle boxes by lifting grips and spread apart by hydraulic cylinders, sliding off the bolster ends; the wheelsets are then rolled out onto the transport system. Assembly follows the reverse sequence, with the side frames centered over the axle boxes of the wheelsets.

The station consists of a welded base frame with rail track, a bolster lifter, side frame lifting and spreading grips, a hydraulic power unit and a control panel. All hydraulic cylinders are fitted with pilot-operated check valves, and the lifter has a mechanical lock that prevents the bolster from lowering if pressure is lost. On request the station is supplemented with a side frame tilter, a spring puller and a parts storage rack.
