Main characteristics


1. Main frame and foundation is integration, good stiffness and high stability.


2. Axle of rotation adopts simple strut-beam, good stiffness, simple and reliable structure and high precision.


3. Round pendulum makes wind resistance to mini.Impact knife adopts wedge block to compress and install.It is easy to exchange.


4. Suspension pendulum device adopts hydraulic buffer to avoid damage and low noise when hang pendulum.It extends service life and improves safety.


5. This machine adopts reducer to transport. Its structure is simple, easy to install and maintain, long service life and low breakdown rate.


6. Three kinds of display modes, they display at the same time.Their results can compare with each other to remove possible problems.


7. It has samples recycling device. The device outputs broke sample from testing machine after impact to avoid tester to recycle broke sample from testing machine and improve efficiency and safety.


8. It has totally closed safety net to avoid broke sample to splash and tester to approach testing machine when processing test and ensure tester and equipment safe.


9. Control system adopts Germany Siemens PLC and Japanese imported high-precision rotary encoder to get timely angle of pendulum. Anti-interference of system is strong. It has the characteristics of reliability, stability,accurate data and others.
