A3 Modular Series HydraJac The HydraJac Stud Tensioner provides accurate and versatile tensioning of bolts and studs whilst being fast, simple and safe to use.

The HydraJac uses hydraulic pressure to tension the bolt to the exact load required. Once the bolt has been tensioned, the nut is wound down the thread to retain the load. The HydraJac is then de-pressurised, released and ready to use again.

Suitable for: The HydraJac is suitable for use where: • Accurate and reliable loading is required on bolting. • Vibrational or torsional stresses are a problem. • Regular maintenance requires repeated adjustment or removal of nuts. • There are confined and difficult nut locations. • Simultaneous tightening of bolts is required

(eg: Flanges)

Features: • Reduces maintenance down time. • Improves safety on the job by eliminating hammer tightening. • Gives reliable and precise tensioning. • Is user friendly - fast to fit and remove. • Requires little physical effort. • Is ideal for confined spaces or difficult locations. • Multiple tensioning for leak-free flange makeup.

A3 HydraJac Technical Specifications

A2 Dedicated Series HydraJac The HydraJac Stud Tensioner utilizes the power of hydraulic pressure to easily produce the forces necessary to effectively tension bolts and studs. Once the HydraJac is in place, screwed onto the bolt’s thread over the standard nut, the required pressure is applied to stretch the bolt to its recommended preload, and the nut screwed down to retain the load. The pressure is relieved, the HydraJac removed and is ready to use again. HydraJac Dedicated Thread Stud Tensioners provide the answer to many of the fitting problems associated with using larger tensioning equipment. They are also ideal for single task applications which do not require interchangeability of thread sizes. Any number of HydraJacs can be interlinked to provide even amounts of simultaneous tension over multiple studs or bolts as required. Produced from high strength alloy steel, HydraJac Stud Tensioners are made in standard configurations. They can also be made to suit the requirements of a specific application.

Suitable for: The EziTite® is suitable for use where: • Accurate and reliable loading is required on bolting. • Vibrational or torsional stresses are a problem. • Regular maintenance requires repeated adjustment or removal of nuts. • There are confined and difficult nut locations. • Simultaneous tightening of bolts is required (eg:

Flanges) • No torque means used (eg: Foundation Bolts)

Features: • Reduces maintenance down time. • Improves safety on the job by eliminating hammer tightening. • Gives reliable and precise tensioning. • Is user friendly - fast to fit and remove. • Requires little physical effort. • Is ideal for confined spaces or difficult locations. • Multiple tensioning for leak-free flange makeup.

Operation Although smaller and lighter than many competitive types, HydraJac Stud Tensioners are capable of high application forces. The higher forces generated by HydraJac devices permit their use with bolts of very high tensile strength, for example, in bolting of highly stressed assemblies or those prone to destructive vibration. Operation of HydraJac at typical lower charge pressures requires less use of costly pumping equipment, and with an improved degree of safety. All HydraJac tensioners are designed to use seals which can be easily replaced in minutes, eliminating expensive repairs.
