ABSTRACT:
An apparatus and a method are provided for controllably applying a force for actuating a belt scraper mechanism by the use of pressurized water to move a cylinder slidingly contained within a cylinder preferably made of a non-corrodable and non-magnetic material. In one aspect of the invention, the water-pressurized cylinder is mounted in a manner that permits ready resetting to determine the maximum force with which the belt scraping is effected. In another aspect of the invention, the force generated by pressurized water to actuate a blade scrapper mechanism is applied thereto through resilient means capable of absorbing incidental shock loading.
