Abstract: 1286158 Wheel-set lathes STANRAY CORP 29 June 1970 31453/70 Heading B3T In an underfloor railway vehicle wheel-set truing machine there is provided means for raising and lowering each wheel set whilst in the railway vehicle to facilitate the machining of the wheel treads and flanges in situ. The means comprises a pivotable frame 58 supported on a base 61 on a foundation beneath the rails and transversely thereto and having arms 57 at each end which carry supporting and driving wheels 56, the frame being pivotable about trunnions 59 by hydraulically actuated piston-and-cylinder units 73, 74 which are connected to the arms 57 and carried in pivotable frame 66. In operation, the railway vehicle is moved along the rails into position over the machine, the hydraulic units 73, 74 are actuated to pivot the frame 58 to effect engagement between the support and driving wheels 56 to lift the wheel-set off the rails and the rail sections 36 are then displaced to provide an opening for the location of the centering and machining heads 46. The heads 46 are brought into alignment with the wheel set, the centres 47 being brought into engagement with centre recesses in the ends of the wheel set and rotary cutters are actuated to effect machining of the wheels of the wheel set. When the machining operation is completed the heads 46 are lowered, the rail sections replaced and the finished wheel set lowered on to the rails. The vehicle is then moved into position for the next wheel truing operation.
