(54) Title: ENDLESS BELT FLEXIBLE TUBE CLEANING LANCE DRIVE APPARATUS (57) : A flexible lance drive device has at least one drive motor in a first portion of a housing and a drive axle projecting across a second portion of the housing carrying a cylindrical spline drive roller. A plurality of cylindrical guide rollers on fixed axles span across the second portion of the housing aligned parallel to the spline drive roller. An endless belt wrapped around the at least one spline drive roller and guide rollers has a generally smooth outer surface and a transverse splined inner surface having splines shaped complementary to splines on the spline drive roller. A bias member supports a plurality of follower rollers each aligned vertically above one of the at least one spline drive roller and guide rollers operable to press each follower roller toward one of rollers to frictionally grip a flexible lance hose when sandwiched between the follower rollers and the endless belt.
