ABSTRACT:
A remotely controlled hydraulically operated cleaner apparatus for use in cleaning the interior of a conduit or pipe comprises a control means located outside of the conduit for generating control signals for controlling the operation of the cleaner apparatus. A source of pressurized hydraulic fluid is connected to valve means for receiving and distributing hydraulic fluid in accordance with control signals received from the control means. The apparatus further includes a housing containing a hydraulically powered motor adapted to receive hydraulic fluid from the valve means. An adjustable cleaner tool means is provided for cooperating with the motor for rotation relative to the conduit, the cleaner tool means being adjustable in order to maintain engagement with the interior walls of the conduit. The housing is supported within the conduit by an adjustable support means and a hydraulically actuated means is provided for receiving hydraulic fluid from the valve means for adjusting the adjustable support means to maintain the housing generally radially centered within the conduit. In the presently preferred embodiment, the cleaner tool means and the support means are concurrently adjustable and cooperate to have the same relative outer boundary to engage the conduit.
