hynew^® Hydraulic Head Nut

Since the development of the Gyratory Crusher, the quarrying industry has sought better means for effective and
safely tightening mantle head nuts。

Technofast Industries have successfully developed the hynew^® Hydraulic Head Nut System to replace standard
mantle Head Nuts。 In additions to technical and performance criteria, major considerations of the design are
aimed at protection of operators from strike or shrapnel injuries commonly occurring when hammering tight
the standard mantle head nut。

The hynew^® features an hydraulic clamping nut with an integral sacrificial protective cover which can be
constructed according to the abrasive nature of the material being crushed。

Features:
Precise clamping forces are generated by hydraulic pressure acting on a constrained area within the hynew^®
Hydraulic Head Nuts and are fitted with mechanical locking rings to 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。

Advantages:

• Vastly reduces downtime and maintenance problems。
• Improves productivity。
• Greatly enhances mantle shaft life, by reducing the damage
• Repeatable accuracy of the tensioning operation reduces product variation
• Is user friendly, fast and easy to fit。
• Minimises risk of personal injury and collateral damage to capital equipment during changes of wearing parts。
• Threaded locking collar counteracts loosening forces of impact on rotating shafts。
• Requires low level of skill for operation。
