摘要: A sludge cleaning lance advancing apparatus includes a frame having lead screw rotatably disposed in the frame. An electric stepping motor is connected to and belt pulley drive between for rotating upon rotation of shaft motor. carrier has an internal thread engaging screw, are so arranged constructed that moved longitudinally relative as rotated carrier. carried by handwheel attached manually initially position lance. alignment rod provided aid this initial positioning.
