Spring Fatigue Testing Machine with Cycle Counter

Multi-station machine that cycles compression springs between fixed heights to determine fatigue life. Used in valve spring and suspension spring development labs. Every station stops on its own when a spring fails, so cycle life is logged per spring.

Specification

Springs are compressed by crank-driven plungers at a set stroke and frequency. Each station has a failure sensor that stops the count when a spring breaks, so cycles to failure are logged individually.

Features

• Six independent test stations
• Stroke adjustable by eccentric
• Frequency up to 20 Hz
• Automatic stop on spring breakage
• Cycle count to 99,999,999 per station
