ABSTRACT:
A machine for washing and/or filling containers such as beer kegs has a walking beam conveyor for moving the containers through the machine from one station to another. The walking beam is raised and lowered by two spaced-apart upright pneumatic rams and to maintain the walking beam in its correct attitude regardless of variations with loads upon it, a spaced-apart pair of double-acting hydraulic pistons and cylinders are arranged to act between the walking beam and a base frame of the machine, the cylinders being cross-connected so that the pistons are constrained to move in unison by the movement of hydraulic liquid between the cylinders. Preferably, each of the hydraulic pistons and cylinders is incorporated co-axially as a unit with one of the pneumatic rams.
