Springs keep the tills ringing

摘要

Torsion springs extend the operational life of cash tills by eliminating closure failure. Cash tills are in constant use in stores around the world and checkout operators demand that they operate reliably and smoothly. Most cash tills use a spring to perform the opening and closing operation of the cash drawer and one till manufacturer was experiencing problems with the closing operation, with failures occurring after 200,000 to 300,000 operations.
