MLT24 - Mechanical Load Tester
The MLT24 is our most advanced test stand to simulate static and dynamic loads on modules and collectors. Twenty-four pneumatic cylinders with vacuum suction cups exert both compressive and tensile loads on the test sample, while reducing local mechanical stress points. The MLT24 is a reliability test stand for quality and product development testing. It offers a high degree of operational ease and flexibility. A high total exertable force allows product development with testing to failure.
