The carriage support rail is in the form of a box-shaped beam having inwardly directed flanges at its underside and the chain is mounted inside the box-shaped beam to be protectively enclosed in the beam and the carriage has wheel mounting portions extending upwardly into the beam at opposite sides of the chain and carriage support wheels mounted on the wheel mounting portions inside the beam and in rolling engagement with the flanges on the beam to support the carriage for movement therealong. The chain has upper and lower runs extending lengthwise of the tank and carries a drive lug, and the carriage has an upper and a lower follower alternately engaged by the drive lug as it moves respectively along the upper and lower runs of the chain to reciprocate the carriage.
