A2 EziJac

The EziJac Stud Tensioner utilizes the power of hydraulic pressure to easily produce the forces necessary to effectively tension bolts and studs.

EziJac 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 EziJac can be interlinked to provide even amounts of simultaneous tension over multiple studs or bolts as required.

Produced from high strength alloy steel, EziJac Stud Tensioners are made in standard configurations. They can also be made to suit the requirements of a specific application.

The EziJac provides the following advantages:

• 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.

Although smaller and lighter than many competitive types, EziJac Stud Tensioners are capable of high application forces. The higher forces generated by EziJac devices permit their use with bolts of very high tensile strength, for example, in bolting of highly stresses assemblies or those prone to destructive vibration.

 Operation of EziJac at typical lower charge pressures requires less use of costly pumping equipment, and with an improved degree of safety. All EziJac tensioners are designed to use seals which can be easily replaced in minutes, eliminating expensive repairs.

Typical EziJac applications are found in many industries, including:

• Mining and Quarrying
• Oil and Gas
• Marine
• Power Generation
• Agricultural
• Structural
• Heavy Equipment in general industry
• Chemical Plants

Once the EziJac is in place, screwed onto the bolts 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 EziJac removed and is ready to use again.
