In the industry, the market offers to the user several usual systems to create linear motion.
Generally, these systems include hydraulic or pneumatic cylinders, or electro-mechanical spindle drives. Also cam, disk or redirection systems are often used.
The thrust chain is a novelty among these systems. A special chain that, unlike the known traction chain, becomes rigid in the thrust direction. It nevertheless can be redirected with sprockets.
The classical power transmission element, the endless chain with at least two sprocket wheels (drive and return) and a tensioning element becomes a “finished” chain with two free ends. The drive can be positioned at any point.
The thrust ability is ensured by specially formed chain links that interlock and support each other with minimum play. The load is attached to one end of the chain, e.g. by means of a latch or of a hook. To that purpose, the chain ends are provided with transversal holes for screws or bolts.
During the move, this latch / hook interlocks with the pushed load or its support.
The other free chain end can be guided according to the needs. To save space, it is rolled in a magazine. This space-saving design is one of the main advantages of the system.
