Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The digital display geotextile tensile tester is a new generation of testing instrument developed by Ji'nan platinum Testing Technology Co., Ltd. The test machine is equipped with the special fixture of the geotextile test. It can complete the geotextile and strip stretching (220mm, 120mm) geotextile top breaking, piercing, CBR top breaking, tearing, holding, geogrid tensile test and so on. It is a necessary test machine for transportation, water conservancy, tunnel, construction engineering and other industries.

GB/T13763-2010 "determination of tearing strength of geosynthetics"

GB/T14800-1993 "test method for bursting strength of geotextiles"

GB/T15788-2005 "geotextiles and related products wide strip tensile test"

SL/T235-1999 "testing rules for geosynthetics"

JJG475-2008 verification regulation for electronic universal testing machine

GB/T2611-2007 "general technical requirements for testing machines"

1. The geotextile test machine adopts AC servo motor and servo speed control system motor as driving system with high speed speed and stable performance. It has over current, overvoltage, overload and so on.

2, automatic display: in the whole test process, the LCD can display the test force and peak value in real time.

3. Automatic control: after the test parameters are input, the test process can be completed automatically.

4, breaking judgement: after the specimen is fractured, the moving beam stops moving automatically.

5, limit protection: with mechanical and programmable two level limit protection function;

6, the transmission part adopts the circular arc synchronous tooth belt, the precision screw pair transmission is stable, the noise is low, and the transmission efficiency is high.

7, the universal joint uses the cross pin structure, and has the angle limiting function. On the one hand, it is easy to hold the sample and ensure the test concentricity. On the other hand, the influence of the irregular sample on the sensor is eliminated.
