A system for cable abnormality detection is disclosed. The system includes a laser sensor measurement system for measuring a cable diameter and insulator jacket coating thickness of a cable and a guide assembly for guiding entry of the cable through the laser sensor measurement system. The system further includes a control system with a memory and a processor that executes computer-executable instructions and causes the processor to: measure the cable diameter with respect to upper limits of the cable diameter; determine that the cable diameter is outside of the upper limits using the cable diameter measurements and cable parameter tolerances; and initiate a signal to stop the cable from advancing, in response to determining that the cable diameter is outside of the upper limits.

An apparatus for driving a flexible lance hose into and out of tubes in a heat exchanger tube sheet includes a housing and an upper endless belt drive assembly and a lower endless belt drive assembly spaced apart by a gap for receiving a flexible lance hose therein. One of the drive assemblies is fixed to the housing. The other drive assembly is movable within the housing toward and away from the one endless belt drive assembly. The apparatus further includes a drive motor fastened to the housing configured to engage at least one of the upper and lower endless belts and drive a flexible lance hose disposed in the gap.
