ABSTRACT:
The apparatus of the invention includes a mounting frame which is pivotally mounted on the load drum carriage and is pivotally positioned by a pneumatic positioner. A cleaning brush assembly is rotatably mounted on the mounting frame so that, as the actuater moves the mounting frame toward the load drum surface, the cleaning brush assembly engages the periphery of the load drum to clean same. A drive motor is provided for rotating the cleaning brush assembly as it is pressed against the surface of the drum. The pneumatic actuator is connected to a regulated fluid pressure source so that the force with which the cleaning brush assembly is pressed against the drum surface can be regulated and is maintained below the unloaded threshhold force at which the load drum controller is set to prevent automatically rezeroing the load set point of the load drum.
