The MLT15 is our basic mechanical load test stand. It simulates static and
dynamic loads and is suitable for load testing according to international standards
for modules of typical size. Twelve pneumatic cylinders with vacuum
suction cups exert both compressive and tensile loads on the test sample.
The MLT15 is an excellent product for basic testing. Manual test setup and
adjustment is accomplished quickly and easily. Cylinders are activated or
deactivated with manual ball valves and can be positioned individually to
achieve any desired (even non uniform) suction cup arrangement.
