Product Features
Primarily designed for 10.9-grade high-strength bolts.
Maximum working pressure: 150 MPa (1,500 bar).
Equipped with an automatic rapid-return mechanism for faster piston retraction after each tensioning cycle.
Features a red stroke indicator line to provide a clear visual warning when the piston approaches or exceeds its allowable stroke.
Equipped with an interchangeable tensioning head, allowing adaptation to different bolt sizes and applications.
Standard surface treatment includes polishing and black oxide coating for improved corrosion and wear resistance.
Incorporates a mechanical over-stroke limiting mechanism to protect the tensioner from excessive piston travel.
Features a multi-stage hydraulic design with multiple cylinders, providing high tensioning force within a compact overall size.
Optional Accessories
Safety protective cover
Spring-loaded nut rotation socket
Nickel-plated surface coating for enhanced corrosion protection
Hydraulic manifold / distributor connection
Bolt elongation measuring rod
