ABSTRACT:
Protection apparatus in a mobile sewer cleaning machine having a compartment enclosing a reel and a hose wound thereon. The compartment has an opening through which the hose can be unwound into a sewer through a sewer opening, which leaves a portion of hose between the opening of the compartment and the sewer exposed. The reel and the hose are rotated by a motor to advance the hose through the sewer. The protection apparatus comprises a shield arrangement for enclosing the periphery of the exposed portion of the hose received through an opening therein and extending substantially the full length of the exposed portion of the hose toward the sewer opening. The shield arrangement is fastened to the cleaning machine so that the shield arrangement covers the opening in the compartment. The protection apparatus further comprises sensing means, mounted below the reel and the hose, for sensing the presence of a descending loop of hose from the reel and for providing a stop signal in response thereto, and actuating means, connected to the sensing means, for stopping the motor in response to the stop signal.
