Abstract
A compact flexible lance propelling apparatus is disclosed that is mountable on a pipe end. The apparatus includes a drive mechanism, an adaptable support that can be fastened directly to the pipe end which carries the drive mechanism, a remote control console, and a hose take-up drum spaced from the drive mechanism. The drive mechanism includes a driven roller and a follower roller sandwiching the flexible lance hose therebetween and a rotary cam lift mechanism for linearly raising the follower roller to permit insertion of the flexible lance hose and lowering the follower roller against the driven roller.
