Custom Mechanical Load Testing Systems

If you are looking for a mechanical load testing system tailored to your specific testing requirements, we are the right partner.

Over the years, we have successfully developed and delivered numerous custom testing solutions for customers with unique applications. Our engineering team designs and manufactures mechanical load testers that are precisely adapted to your products, test standards, and environmental conditions.

Examples of Custom Solutions:

MLTSys

Mechanical load testing system for photovoltaic (PV) modules and solar thermal collectors, designed for operation inside a climate chamber, including the complete support structure. The adjustable bridge system allows testing of both flat-mounted and tilted installations by adapting the load application height.

MLT64

Mechanical load testing system equipped with 64 pneumatic cylinders, capable of applying forces of up to 6 kN. Designed for testing two PV modules mounted on a torque tube of a single-axis solar tracker. The system features 16 independently controlled load zones, enabling realistic non-uniform load distribution and advanced mechanical stress testing.

Key facts

  • Tests collectors with the entire assembly system
  • Housed in a climate chamber
  • Climate conditions in test chamber from -40 °C to +60 °C
  • Wind and snow loads up to 6,000 Pa on the entire test area (push and pull)
  • Cyclical and asymmetric loads
  • Maximum size of test surface 3 m × 4 m
  • Tests inclined installed samples, e.g. thermosiphon and PV systems
  • Remote controlled camera
  • Fast and precise cylinder positioning through coupling of the cylinders

Other Mechanical Load Testers

Software features

  • Intuitive graphical user interface for full remote control of the test stand
  • Predefined load cycles according to international standards as ISO 9806
  • Customized test schedules (even non-cyclic, free definition of various load setpoints, can be saved and restored)
  • Real-time visualization of key measurements in graphical displays
  • Quick and easy test scheduling – through displaying of required testing times. Automatic start of tests at predefined start times possible.
  • Remote view via camera

MLTSYS is equipped with highly sensitive force sensors enabling detection of applied forces in all three directions (3D). This allows the examination of thrust forces. Please see page 16-19 for our standardized test stands to simulate static and dynamic loads on modules and collectors, other variations are readily possible. We will be pleased to tailor the test stand MLTSYS to your needs!
