Abstract
A shock absorbing load carrier for an inverted power and free conveyor includes a telescoping main frame formed by a leading inner tubular member received in a trailing outer tubular member with a shock absorbing arrangement engaged therebetween. A drive trolley is connected to a front end of the inner member, and a support trolley is connected to a rear end of the outer member. A load supporting framework is mounted on the outer member for fastening a load to be carried thereon. The shock absorbing arrangement includes a damping chamber formed in the inner member and a piston member connected by a rod to the outer member. A particulate damping material, such as a quantity of ball bearings is positioned in the damping chamber. Relative movement of the inner and outer members caused by abrupt startup or braking of the drive trolley is retarded by resistance to movement of the piston through the damping material, thereby reducing the transfer of shocks from the drive trolley to the load.
