Abstract
A workhead assembly for use in rail applications may comprise a frame and two pairs of workheads, wherein each pair of workheads is disposed on opposing sides of the frame and carries tamping tools. The workhead assembly may further include two vertically-oriented actuators being disposed on opposing sides of the frame. Two pairs of linkage arms are coupled between the vertically-oriented actuator and a pair of tamping arms. Each pair of linkage arms are disposed on opposing sides of the frame. Actuation of the linkage arms imparts movement to the tamping tools.
