First, the anti-slip sheet is installed between the tow chain, so that the mobile end slides on the fixed end to solve the long-distance operation problem of the plastic tow chain to ensure the service life and use effect of the plastic tow chain. Second, the support wheel is installed on the drag chain to support the long distance operation of the plastic drag chain, the support wheel is used to reduce the weight problem of the plastic drag chain to solve the problem of the long distance operation of the plastic drag chain, the installation of the plastic drag chain support wheel must be scientific and reasonable, so as to more effectively assist the long distance operation of the plastic drag chain. Third, the drag chain is equipped with a guide groove, so that the plastic drag chain runs in accordance with the pre-designed drag chain trajectory under the action of the guide groove. When the long distance operation of the tow chain, it is necessary to formulate a reaso…
