Suspension Spring Test Machine

Model 1340

The Greening Model 1340 Suspension Spring Test Machine is designed to evaluate automotive and trailer leaf springs. The basic design utilizes design elements of load frame, fixturing, cylinder, and pneumatic over hydraulic actuator to conduct leaf spring compression tests. The stand may be free standing or secured to the floor. A GAI control computer and software system is employed for force and displacement control. The GAI control system will log and display test data on screen and has the ability to export a data file or graph to a printer. The control computer and monitor may be located on an adjacent bench or desk or mounted on a wall support and suspension arm (optional).
