It is used to determine the constant load creep and constant elongation relaxation properties of various geotechnical materials under high and low temperature, normal loading, corrosive liquid and other test conditions.

GB/T17637-1998, JTG E50 T1131-2006, QB/T 2854-2007, etc.

1. The all-stainless steel work surface is easy to clean and tidy up, effectively preventing soil particles from entering the inside of the instrument.

2. Equipped with JIGAOTEST expert test software, the software has a software test report certificate issued by a national inspection and testing agency.

3. High-speed dynamic data collection, which more objectively reflects the mechanical properties of materials;

4. The computer processes reports, graphics, screen displays or printouts

5. Operating software system function: the instrument can be connected to the PC: record the whole process of the test, and display the graph and test data in real time.

6. An all-in-one machine with two functions of constant load creep and constant elongation relaxation, as long as a small number of fixtures are changed, various test conditions such as high and low temperatures, normal loading and corrosive liquids can be achieved.

7. Adopt microcomputer control, human-computer interactive dialogue operation, multiple character input methods, and print and output Chinese reports.

8. The horizontal loading device adopts Panasonic AC servo drive and servo motor to realize full digital speed closed-loop control. It has the advantages of stable speed, wide speed range, high positioning accuracy, etc. The stretching speed can be set arbitrarily digitally.

9. The normal loading device is driven by a servo system or a pneumatic system, which is convenient and reliable.

10. Using pin connection technology, it can quickly and easily change the holder required for the test.
