EziTite Headnut

Technofast Industries have successfully developed the EziTite®  Hydraulic Head Nut System to replace standard mantle Head Nuts.

Since the development of the Gyratory Crusher, mineral processing industries have sought better means to effectively and safely tighten mantle head nuts. Technofast Industries have successfully developed the EziTite®  Hydraulic Head Nut System to replace the outdated, standard mantle Head Nuts. In addition to technical and performance criteria, the major benefits of the design are focused on the protection of operators from strike or shrapnel injuries that commonly occur when hammering the standard mantle head nut tight. The EziTite® features a hydraulic clamping nut and reinforced protective cover which can be constructed according to the abrasive nature of the material being crushed.

Tool Features:

  • Precise clamping forces are generated by hydraulic pressure activation in the optimised containment area of the EziTite® nut.  The Head Nuts are fitted with mechanical locking rings that retain these tensile loads. In the unlikely situation that there is a hydraulic malfunction, a simple, patented breaker-ring (that is positioned between the lock ring and the nut body) can be used to release the load on the shaft.

Benefits of the EziTite®  Hydraulic Head Nut

  • Vastly reduces downtime and maintenance problems
  • Improves productivity
  • Greatly enhances tool life
  • Repeatable accuracy of the tensioning operation reduces product variation
  • Achieves faster throughput without compromising product quality
  • Minimises risk of personal injury and collateral damage to capital equipment during blade and tool changes
  • Threaded locking collar counteracts loosening forces of impact on rotating shafts
  • Requires low level of skill for operation

EziTite Hydraulic Nut

The EziTite® Hydraulic Nut is a precision engineered, high pressure/high performance, hydraulically operated bolt tensioning device that can be quickly and easily fitted and used with Technofast pumping equipment.

The EziTite hydraulic nut is ideal for tensioning all of the studs on a flange, joint or cover – simultaneously loading 100% of the fasteners at once. This ensures an extremely accurate and balanced load onto the flange/joint.

EziTite Features:

  • Reduces maintenance down time
  • Improves safety on the job
  • Gives reliable and precise tensioning
  • Is user-friendly
  • Fast to fit and remove
  • Requires little physical effort
  • Is ideal for difficult or confined spaces

The EziTite® Hydraulic Nut is Ideal 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 or difficult nut locations

EziTite TR Hydraulic Nut

Tool Features:

  • The patented metal-to-metal seal design allows for applications in temperature conditions upwards of 550˚C
  • Compact Design for tight, confined applications
  • Smart design to eliminate load losses
  • Secondary backup release mechanism (Sacrificial ring)
  • Multiple tensioning provides even bolt loads and short assembly/disassembly down time

Benefits of the EziTite® TR Hydraulic Nut:

  • Reduces maintenance down time
  • Improves safety on the job
  • Gives reliable and precise tensioning
  • Is user-friendly
  • Fast to fit and remove
  • Requires little physical effort
  • Is ideal for difficult or confined spaces

The EziTite® Hydraulic Nut is Ideal for:

  • Pressure Vessel Closure(i.e.: Autoclaves, Boilers, etc)
  • Flange Makeup
  • Gas Turbine Joints
  • Steam Turbine Joints
  • High Temperature applications

Clamp Nut

EziTite® Hydraulic Clamp Nuts are the modern, safe and efficient way to ensure precise tool clamping.

EziTite® Hydraulic Clamp Nuts replace conventional, torque-loaded threaded nuts to make shaft tensioning a simple, safe and efficient hydraulically assisted operation. They are also widely used to set large shaft bearings. Our Clamp Nuts are manufactured in a wide range of sizes to suit applications throughout many industries. EziTite® Hydraulic Clamp Nuts are made in a standard range to suit thread sizes from 50mm to 300mm – additional sizes can be tailored by request.

 Tool Features:

  • Vastly reduces downtime and maintenance problems
  • Improves productivity
  • Is user friendly, fast and easy to fit
  • Greatly enhances tool life
  • Repeatable accuracy of the tensioning operation reduces product variation
  • Achieves faster throughput without compromising product quality
  • Minimises risk of personal injury and collateral damage to capital equipment during blade and tool changes
  • Threaded locking collar counteracts loosening forces of impact on rotating shafts

Benefits of EziTite® Hydraulic Clamp Nuts:

  • Accurate hydraulic loading
  • Positive locking with mechanical ring
  • Replaces lug wrench and hammer method
  • Increases worker safety – decreases injury potential

EziTite® Hydraulic Clamp Nuts are Ideal 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 or difficult nut locations

Cam Nut

Technofast’s revolutionary Cam Nut EziJac system creates an affordable and efficient solution, in a compact system that is simple, safe and easy to use.

Normally, Bolt Tensioning tools pull on the bolt threads protruding above the regular hex nut, which are then screwed down to retain the loads induced by hydraulic operation of the tool.  With no available thread, the Cam Nut performs as the connection to the bolt for the operation. Its integral collar expands to take up  the bolt’s elongation under force and retains the load when the hydraulic charging pressure is released.

 Tool Features:

User friendly, fast to fit & remove.

    • Requires little physical effort
    • Quick connection from nut to Tensioner
    • Ideal for situations with short bolt grip length
    • Modular construction reduces overall tool weight
    • Operating temperatures from –40 deg to +650 deg C

Benefits of using a Cam Nut:

    • No longer need to replace expensive studs to provide sufficient grip length
    • Modular construction reduces overall tool weight
    • Designed for extreme situations/adverse conditions
    • Minimises cost
    • Reduces downtime
    • Achievable reliable and precise tensioning the first time
    • User friendly to improve safety
    • Requires little physical effort
    • Fast to fit and remove
    • Reduce breakdowns and damage
    • Removes risk of strike and pinch point injuries caused by other tightening methods

A Cam Nut is Ideal where:

    • Regular maintenance requires repeated adjustment or removal of nuts
    • Speed of operation is essential
    • Bolts are of large diameter
    • Accurate and reliable loading is required on bolting
    • Space for tooling is restricted
    • Simultaneous tightening of bolts is required
    • Even joint/gasket compression is required
