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 Technofast Industries have successfully developed the EziTite®  Hydraulic Head Nut System to replace the outdated, standard mantle Head Nuts.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

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

FastJac

Technofast’s FastaJac saves on Production, Labor and Maintenance Costs for Manufacturers and End Users of Plate Heat Exchangers.

The use of a lightweight hollow cylinder jack, in conjunction with the patented ‘Tri Nut’, allows the compression of plates to be  carried out evenly, squarely and efficiently. The hydraulic cylinders simultaneously compress the plates. The Tri-Nut is designed to fit over the major diameter of the thread until it engages into it’s spherical seat. Then the nut closes onto the thread and the nut is screwed home as normal. This facilitates speedy fitting and removal of the tools  removing the need for ‘running down’ the Tensioner retaining nut over the full length of the thread.

Tool Features:

  • The Patented ‘Tri Nut’ allows the Tensioner to be removed and installed on the exchanger quickly
  • The hydraulic cylinders simultaneously compress the plates so the compression of plates are carried out evenly, squarely and efficiently
  •  Unique cam lock design
  • Tri Nut locks into tool, even in upside down position
  • Quick connect fittings
  • No Pinch Points
