An apparatus for installing and removing candles from a packed tower comprises a rail or series of rails attached to the inside of the top of the vessel. The rail(s) may be supported from either the roof or walls of the tower. A traveler assembly is supported on the rail(s). The traveler assembly supports a hoist puller that in turn raises and lowers the candles. The rail(s) may be located such that they extend over the centerlines of each of the candle locations, and each such that a portion of each rail passes under the candle installation port. Multiple traveler assemblies may be used to increase the speed of installation. The traveler assembly may be configured to be removed when not in use, to ensure it is not exposed to the harsh environment in the tower. Alternatively, the traveler assembly may be constructed from corrosion-resistant materials, so that the traveler assembly may be left in the tower.
