Product Details
400kN Anti-Slip Coefficient Testing Instrument HY-24L
1. Product Introduction:
- The LLG-24HY anti-slip coefficient testing instrument is mainly suitable for testing the anti-slip coefficient of friction surfaces in high-strength bolt connections of grade 10.9 and 8.8, as well as for testing the anti-slip coefficient of friction surfaces in torsional shear type high-strength bolt connections (a special wrench for torsional shear needs to be ordered separately), testing, and research.
- High-strength bolt connection: A general term for high-strength bolts and their matching nuts and washers;
- Anti-slip coefficient: The ratio of the external force that causes the friction surface of the connection to slide to the sum of the pre-tension of the high-strength bolt perpendicular to the friction surface in high-strength bolt connections;
- LLG-TEST LCD microcomputer force measuring instrument, with four physical channels and a total of 24 logical channels in 6 groups.
- Parameter backup and recovery function, peak hold function, automatic calibration function.
- Specifications for high-strength large hexagon head bolts: M16, M20, M22, M24, M27, M30.
- Specifications for torsional shear type high-strength bolts: M16, M20, M22, M24.
- To facilitate users in connecting to a computer, the LLG358 interface is set up (needs to be ordered separately), allowing data to be transmitted to a computer for further processing and printing of test reports.
- This device is easy to operate, convenient to carry if sent for calibration by measurement departments, and extremely convenient for future equipment upgrades and maintenance. This device is currently a low-investment, high-return high-strength bolt testing instrument widely popular among high-strength bolt manufacturing enterprises, engineering quality testing institutions, steel structure construction units, engineering supervision agencies, high-speed railways, bridge electricity, and research institutions such as colleges and universities in China.
