Now that’s sweet – Technofast’s cost-crushing fastener technology rolls out big maintenance savings and safety gains for mill operators

Technofast EziTite® hydraulic nuts were tensioned simultaneously to ensure an even tensioning force over all units, extending reliability and operational safety.

An Australian fastening technology proven globally in some of the most demanding primary industry crushing, milling and materials processing applications has once again demonstrated its ability to slash maintenance downtime while increasing safety and productivity. 

The Technofast EziTite® hydraulic nuts – which are also applicable to mining and quarrying applications – are being used by Northern NSW sugar mills to speedily secure and release roller clamping, mill stand and cap bolts in less than a third of the time taken previously. 

The rapidly installed EziTite nuts were supplied by Norbar Australia – a specialised distributor of Technofast hydraulic bolt tensioning products – and installed by Technofast’s Technical Solutions specialist, Matt Blundell. 

The simultaneously actuated hydraulic nuts, used in place of the previous flogging spanners, precisely tension multiple hex nuts up to 5in (127mm) diameter by stretching the bolt with hydraulic tensioning during installation then locking it in place in a clean and fast operation. 

The ruggedly reliable nuts (which have decades of service in different applications) can be simultaneously and easily de-tensioned as required for roller and other machinery maintenance. This cuts downtime of vital machinery operating continuously during harvesting, while at the same time curtailing OH&S concerns about working at heights within confined spaces using physically demanding heavy tools with no control of bolt loads to ensure ongoing reliability and safety. 

Operators reviewing the EziTite installation report major time and safety gains with the technology, which simplifies operational and installation processes and applies precise bolt loads.

Results of the installations include: 

  • Roller clamping hex nuts – actuated simultaneously by a Technofast hydraulic pump configured with 4-way manifold – are installed in 30-60 minutes by two personnel, compared with 4.5 hours previously, with 2-3 or more personnel. Time savings achieved at the busy mill total 3-4 hours per operation, with maintenance personal reporting that the EziTite nuts are much faster to use and require less effort to install. They remove hard manual labour and OH&S risks. 
  • The mill stand and cap bolts application is similarly far swifter. It now takes an hour using two personnel, compared with four hours and 30 minutes for the old method, which used 2-3 personnel. Again, on-site maintenance personnel report the EziTite nuts are much faster and require less effort to install. 

“These are big savings in downtime and major increases in safety in a seasonal industry, says international fastening specialist John Bucknell, Founder and CEO of Technofast precision engineered solutions. “Primary industries such as sugar can be extremely busy during harvesting time with many people operating under arduous conditions. Technologies that can save time and cost, while increasing safety, are wonderful for staff and wonderful for the bottom line”.  

Technofast fastening solutions are used globally in time and safety-conscious industries with the highest operational standards, ranging from nuclear, fossil and green power plants through to hard rock mining and quarries where reliability and safety is essential. (www.technofast.com
