A cushioned tow bar for connecting a drive trolley to a load carriage in a power and free conveyor system includes a particulate shock absorber with a damping chamber which is partially filled with particulate material, such as small ball bearings, which act to dampen the movement of a piston through the damping chamber. The damping chamber comprises a portion of a sleeve which includes a threaded end cap which mates with threads on an open end of the sleeve. The threads in the sleeve extend along the longitudinal axis of the sleeve to an extent which allows the end cap to be threadably adjusted, changing the portion of the sleeve forming the damping chamber, and thus adjusting the cushioning effect of the tow bar.
