Abstract: A rodless cylinder using a round stick type chain can be applied to a carrier for transportation of materials. The rodless cylinder uses a round stick type chain having the round stick type chain and the chain sprocket, which serve to guide the round stick type chain in a caterpillar form. The chain sprocket is axially formed on either side of the frame consisting of the rodless cylinder to install the round stick type chain in a caterpillar form. Both sides of the round stick type chain are connected to a piston within the cylinder on the frame and to a tension adjustment nut on the connector, respectively. The connector is guided to the guide bar formed between the frame vertically and selectively linked to the carrier.

Abstract: This invention relates to a rodless cylinder using a round stick type chain, wherein it can be applied to an elevator or a carrier for horizontal movement for the efficient transportation of materials in the industrial fields with better durability and safety of rodless cylinder, as well as the cost-saving effects in manufacture. This invention further related to the rodless cylinder using a round stick type chain having the round stick type chain and the chain sprocket which serves to guide the round stick type chain in a caterpillar form.

Abstract: This invention relates to a chain driving means of round shaped stick comprising a chain of round shaped stick and a chain sprocket which is mutually geared to chain driving means of round shaped stick for its driving force, thus ensuring better durability and tensile strength.
