Training & Technical Backup
We at HTI have been designing engineered solutions to your toughest bolt tensioning problems for over 35 years! While all our products come with an instruction manual, sometimes it can be helpful for product assembly, service, and field technicians to receive in-person training in the proper use of our hydraulic tensioners, hydraulic nuts, and the pump systems that drive them.
We can also provide training in calculating proper bolt-loading.

Hydraulic Equipment from HTI is specially designed to offer maximum performance stud and bolt tensioning for any application or industry. We offer hydraulic tensioners, hydraulic nuts, and hydraulic pumps. We at HTI can assist you in finding the ideal product to suit your specific requirements.
Variable stud tensioner models allow the tensioning of different bolt/stud sizes or thread forms while utilizing a common load cell.
Single Stage Tensioners
Single-stage tensioners are ideal for applications that are vertically limited. They provide a large amount of stroke in a vertically compact package.
HTI foundation tensioners are designed for the unique constraints of foundation studs for applications such as wind turbine foundations.
Through-hole (also called hollow-piston or hollow-plunger) tensioners are intended for use with long protruding studs, such as for wind turbine foundation bolts, or with a proprietary rolled threaded rod.
High Load & High Stroke Hydraulic Tensioners
HTI long-stroke tensioners are useful in circumstances where a long stud deflection is require to achieve the target stud load.
