A pinless coupling that demonstrates outstanding power in core extraction!
The "PLC-64/74/84" is a pinless coupling that has improved rust prevention and wear resistance effects due to special surface treatment. During drilling, drilling water is sent to the core tube, and when pulling up the boring rod, the water inside the rod is blocked at the top of the core tube to prevent the core (sample) from falling off. 【Features】 ■ Exhibits outstanding power for core sampling ■ Rust prevention and wear resistance effects are enhanced by special surface treatment ■ Resolves concerns about core drop *For more details, please download the PDF or feel free to contact us.
