A PORTABLE DEVICE FOR WORKING OFF EXCESS WELDING MATERIAL ON WELDED RAIL JOINTS

摘要

In the device, two cross members (15, 16) and two guide tubes (13, 14) for guiding two hydraulic cylinders (18) form a frame for the acceptance of the reaction forces which occur during the shearing-off process. The hydraulic cylinders are connected to one another by a further cross member (20), on which one (21) of the shearing cutters is arranged, the said cutter being moved towards the other shearing cutter (19), arranged on the cross member (16) of the frame, when the hydraulic cylinders (18) are pressurised. The piston rods of the hydraulic cylinders (18), which cylinders can be moved in the guide tubes (13, 14), are firmly connected to the cross member (15) of the frame. Due to the fact that the reaction forces can be taken up by the frame, the hydraulic cylinders and hence the entire device can be kept small. IMAGE
