Automated Tensioner saves times and improves quality

Case Study 1: Large Diesel Engine manufacturer fully automates the cylinder head stud tensioning process



  1. Manual torquing is time consuming and imprecise.
  2. Manually tightening with tensioners leaves room for operator errors/omissions and results are hard to document.


Fully automated tensioning system from HTI provides these benefits:

  • All of the Cylinder Head nuts are tightened simultaneously.
  • Computer control eliminates inconsistency.
  • Position sensing assures all studs are properly tensioned.
  • Time savings, since each cylinder head is tensioned in less than two minutes with one operator.
  • Data logging capability documents data for complete process traceability and later review.
