The Alfco Slurry Scraper will scrape cubicle and feed passages of various widths. Up to six passages can be operated on one powerpack and control panel.
One Rambox is installed at the end of each passage and a double acting Ram moves the central draw bar back and forth. The scraper is fitted with a mechanism that moves it forward with each stroke. At the end of the track the Scraper automatically reverses to its parking position, where a switch turns off the hydraulic oil supply.
