Load Frame

This universal material testing machine with hydraulic drive is ideal to test rocks, concrete and other construction materials (Type UL-XXXX SH). The load system can be tailored to customers’ specific requirements e.g. different test jigs, Triaxial or uniaxial tests, concrete tests, combined shear and compression tests with an exclusive software to control load frame in both basic and highly complex applications.

We manufacture different type of hydraulic powerpacks which supply hydraulic fluid for servo hydraulic testing machines to meet the loading requirement of the test. A key feature of our hydraulic power packs is that they offer demand-dependent flow-rate control, delivering at a constant pressure of 210, 280 or 340 bar.

Load frame is compatible for performing direct shear, unconfined compression, triaxial, bending, indirect tensile, direct tensile, fracture toughness, creep, flexural and cyclic loading tests (The hardware for each test should be ordered separately). LOAD FRAME GEOsys software, with several testing modules/ applications for Asphalt, Concrete, Rock triaxial and uniaxial tests controls the test procedures, means it can work as a fully automated system and provides an easy way to create custom test modules.


  • High stiffness and robust 4-column construction designed for uniaxial and triaxial rock testing
  • Wall type load frame also available on request
  • Precise force transducers have been applied to measure and control normal stress
  • Hydraulic power packs with high-quality noise protection, as well as emergency functions
  • Single ended double acting actuator integrated on chassis placed onto vibration isolation pads suitable for studies of post-failure behavior.
  • Expandable real-time high resolution data acquisition and closed-loop control system (20 bit)
  • Easy sample fitting and cleaning
  • Optional Transparent test area guard with front security door
  • Tailor made testing area
  • High-speed, closed-loop control of load, displacement, position and volume or flow
  • The system is capable of applying different stress paths or strain rates
  • Real-time graphics software with zoom and freeze functions for printer output at any time (after and during the test)
  • Carriage assembly for easy removal and placing of triaxial cell
