caption_attribution_description: English: Mount/Demount mechanism that is part of the Coats Rim Clamp tire changer.
context_page_description: A tire changer is a machine used to help tire technicians dismount and mount tires with automobile wheels. After the wheel and tire assembly are removed from the automobile, the tire changer has all the components necessary to remove and replace the tire from the wheel. Different tire changers allow technicians to replace tires on automobiles, motorcycles and heavy-duty trucks. New tire and wheel technology has improved certain tire changers to be able to change a low profile tire or a run-flat tire.
context_section_description: The mount/demount mechanism consists of the duckhead, swing arm, and vertical slide. The duckhead is at the bottom end of the vertical slide. The duckhead is uniquely shaped, like a tapered bill, to fit next and surround the rim of a wheel. It can either be made of metal or plastic. The duckhead mounts and demounts the tire from the wheel. The swing arm moves left and right. The purpose of the swing arm is to move the duck head near or away from the rim. The last component of the mount/demount mechanism is the vertical slide. The vertical slide moves up and down so that the duck head can fit onto the rims of different size wheel widths. The vertical slide has a spring and locking handle above the swing arm to set the duckhead and maintain a stable position around the rim.
