ABSTRACT:
In removing slag by vacuum suction, an upward force is always applied which is greater than the force with which a suction head is attracted downward under the influence of its own weight and that of connected parts. During normal operation, a drive force is applied through a separate drive system to balance the upward force, thus keeping the suction head in the desired position. When the drive force fails, the upward force holds the suction head in the hazard-free raised position.
