Abstract
A tube cleaning system for cleaning tubes such as heat exchanger tubes is capable of driving a variety of diameters of lances. A notch in the drive belts is capable of driving the several diameters. In addition, a clamp biases belt guides against the guides to hold the guides against the lances. Further, a housing for housing the drive mechanism can be pivoted to an open position to facilitate changeover of the lances.
