    摘要： A machine to vibrate railroad rail includes a vehicle movable along the rail and supporting a spring-loaded vibratory shoe which engages the upper surface of the rail. The spring loading may be adjusted to control the intensity of the vibration imparted to the rail.

    摘要： A RAIL LIFTER COMPRISING A RIGID ELONGATED BEAM TO BE SUPPORTED AND MANIPULATED FROM A CRANE OR OTHER CONVENTIONAL MATERIAL LIFTING AND HANDLING DEVICE. A PAIR OF LATERALLY OPPOSED GRIPPERS ARE SUPPORTED AT ADJACENT OPPOSITE ENDS OF THE BEAM FOR ANGULAR MOVEMENT TO AND FROM OPERATIVE POSITIONS IN WHICH THEY PROJECT BENEATH THE BEAM IN SPACED RELATION BELOW IT TO THUS PROJECT BENEATH THE RAIL HEAD OF A RAIL TO PROVIDE SUPPORT FOR THE LATTER. THE GRIPPERS ARE ACTUATED THROUGH CRANK ARMS WHICH ARE LINKED TO THE PISTON RODS OF HYDRAULIC UNITS ARRANGED FOR EXTENSION AND RETRACTION MOVEMENT PARALLEL TO THE BEAM AND IN A MANNER TO PRODUCE THE DESIRED ANGULAR MOVEMENT OF THE SAID GRIPPERS. IN ORDER TO AVOID LONGITUDINAL SLIPPAGE OF THE RAIL THROUGH THE GRIPPERS, THE RAIL HEAD IS THRUST FIRMLY DOWNWARDLY AGAINST THE GRIPPERS PLUNGERS GUIDED FOR VERTICAL MOVEMENT ON THE BEAM AND ACTUATED BY CAM MEANS CARRIED BY THE PLUNGER ROD AT LOCATIONS TO ENGAGE AND DEPRESS THE PLUNGERS ONLY AFTER THE GRIPPERS HAVE MOVED BENEATH THE RAIL HEAD.
