ABSTRACT:
A drive assembly for a probe carrier such as used for inspection and maintenance of a heat exchanger in a steam driven electric power generation plant includes a motor and speed reducer and drive wheel for pushing a probe carrier through the tubes of the heat exchanger. The carrier may comprise nylon tubing, and the drive wheel includes radially mounted wires with the tips of the wires defining a surface for engaging the tubing. An adjustable pressure plate yieldably biases the tubing into engagement with the drive wheel with sufficient pressure for the wire tips to indent the tubing surface but without penetrating the tubing surface whereby an interference drive of the probe carrier is achieved.
