For assembly, clamping elements are screwed on the belt construction. After aligning of the clamping elements, the Duo scraper element is attached to these. At this point, the desired pressure can be set. The wearout of the scraper edge is adjusted automatically through the cramping element. When the first scraper edge is used off, the scraper will be turned by 180° in the installed condition to the second edge. A standard solution with the best price-performance ratio!
Due to the simple construction, the maintenance for the Duo is very low. There are no parts on the Duo that need to be maintained regularly and a cleaning procedure is usually not needed. A simple visual inspection should be performed on a regular basis. Worn-out scraper elements must be replaced.
PU-Scraper elements with different shore-hardening are available for the Duo.
