ABSTRACT:
A device for supporting tamping bench arms and for engagement with a horizontal rib provided on the arm is formed from a pair of parallel rectangular spaced apart side walls (1) interconnected by a back wall (2) and a pair of horizontal plates (4) attached to the upper and lower edges of the back wall (2) and extending from the central surface portion of the back wall approximately half the length of the side walls (1). While the device is suspended from above, the rectangular plates are slid into engagement with the horizontal rib provided on the tamping bench arms, enabling an operator to effortlessly move and manipulate the tamping bench arms.
