1. Intrinsically safe and explosion-proof: Fully pneumatically driven with no electrical components, suitable for high-gas and coal dust explosion-hazardous mines, meeting Class I explosion-proof requirements for coal mines, ensuring a high safety factor.
2. Powerful and efficient tensioning: The pneumatic hydraulic pump provides stable output pressure, enabling fast and labor-saving tensioning. It is several times more efficient than manual tools, significantly reducing worker workload.
3. Simple operation, one person can work independently: A reversing valve controls tensioning, pressure holding, pressure release, and top retraction. The compact structure and lightweight design make it easy to transport; a single person can complete the entire anchor cable tensioning.
4. Automatic anchor locking and retraction: Equipped with a tool anchor and top pressure device, it automatically locks the clamps and retracts the top after tensioning, reducing procedures and minimizing errors.
5. Precise pressure and stable prestress: Equipped with a pressure gauge for direct observation of tension pressure, ensuring accurate tension control and stable and reliable support quality.
6. Strong adaptability and versatility: Compatible with various anchor cable specifications such as Φ15.24, Φ17.8, Φ21.6, and Φ28.6. Simply replace the locking plates for universal compatibility; one machine serves multiple purposes.
7. Low failure rate and convenient maintenance: Simple structure, reliable sealing, few vulnerable parts, easy underground maintenance, and good long-term stability.
8. Excellent pressure holding performance: The hydraulic system has strong sealing performance, maintaining pressure without leakage after tensioning to the correct position, meeting the anchor cable locking requirements.
