    Install the spring tensioner on the side that is most easily accessi- ble. The side that is most easily accessible is called the "operator side" in this manual, while the other side is called the "opposite side". © Martin Engineering GmbH M3699UK-11/13...
  • Page 16: Installation Of The Martin D2H Main Scraper

    Installation of the MARTIN D2H main scraper ® 4.2.1 Determining the installation position The position of the middle axis of the conveyor belt scraper must be determined on both sides of the chute wall. In the process, the posi- tions are determined where the shaft of the conveyor belt scraper passes through the chute wall or where the spring tensioner is in- stalled on the chute wall.
  • Page 17 Spring tensioner Air tensioner Abb. 1: Creating the installation openings in the chute NOTE Martin Engineering recommends for improved maintenance and repair access the installation of a MARTIN ® inspection door. 3. Mark the vertical and horizontal centre line of the driving drum on the operator side of the chute wall to determine the midpoint (A) of the driving drum.
