Engineers designing motion-control devices have a long list of standard, off-the-shelf options to choose from, everything from balls screws to electromagnetics. But the list shrinks dramatically if the application involves long travel distances, high cycles, limited space, heavy loads, or harsh environments. Rigid Chain, can pick up the slack in these challenging applications. Rigid Chain collapses and can be coiled clockwise or counterclockwise. The direction it bends or coils depends on its configuration. And when aligned and pushed in the right direction, it becomes as stiff as a steel column. The chain accomplishes this using articulated links with shoulders that self-support and lock into each other when pushing or lifting a load. In general, Rigid Chain actuators include the chain, drive housing, and storage magazine. Sprockets inside the drive exert the push on the chain, much like conventional chains. But the load being lifted or pushed exerts a reaction force through the chain heel, creating a locking moment on the chain.
