Product Features
Features an automatic rapid-return mechanism, allowing the piston to retract quickly after each tensioning cycle for improved operating efficiency.
Equipped with a red over-stroke warning indicator line, providing a clear visual indication when the piston approaches its maximum allowable stroke.
Features a polished and black-oxide surface treatment for improved corrosion resistance, wear resistance, and long-term durability.
Designed for high-pressure operation while maintaining a lightweight and compact structure for easier handling and on-site use.
Incorporates a three-stage safety protection system to improve operational safety and protect the operator during high-pressure tensioning work.
A single tensioner can be used with different bolt sizes by changing the appropriate accessories, allowing both bolt pre-tensioning and loosening operations with greater flexibility.
