ITH project engineering: implementing customer specific solutions in bolting technology
Since the beginnings in 1979 ITH has successfully implemented numerous individual solutions for business partners and whole industries. For example: transport and lifting devices, automation solutions, lifting or extraction tools, digital documentation, management systems and many more. Those innovative devices have led to significant time and cost reductions for customers because they provide higher efficiency. They speed up processes and make bolting jobs easier and safer.
Bolting project process
Here is a sample process of ITH project engineering:
- Contact
to business partner: competent, objective consultation - Analysis
of the bolted joint / the task / the application - Development of a solution
by the ITH design department - Result
The best technical and most cost effective solution for customers.
Advantages of ITH project engineering
Optimized bolted joint design, innovative bolting tools, or customer-specific solutions lead to cost reductions.
The most cost saving options are achieved by:
- Time saving
(faster bolting procedures, less total assembly time and/or maintenance procedures, reduced costly downtimes of machinery) - Optimized flange design by small alpha-a factors up to 1.1
By achieving small alpha-a factors up to 1.1 , ITH bolting solutions offer:
a.) higher pre-tensioning forces when the bolt sizes and flange dimensions are unchanged
b.) unchanged pre-tensioning forces with smaller bolt sizes and flange dimensions (example: substitution of M72 by M64 with a higher bolt spacing t) which leads to significant cost reductions - Higher working safety
with patented ITH safety features and easier handling - Customer specific solutions
Specific bolting tools like lifting/extracting /spreading devices, hydraulic jacks, automated solutions, or customer-specific management software
Examples of ITH project engineering
Digital input and management systems
Documentation system for bolting technology
Transport and lifting devices
Test and calibration systems
Automation
ITH Autostretch: robot supported automation solution for Bolt Tensioning Cylinders
Application: Automatic tensioning of all bolt connections of wind turbines for high volume production (Bolting slew bearings to the hub).
- Automatic identification of bolts with a 3D camera system and automatic processing
- Automatic tensioning of bolt connections by Auto-BTC with safety management
- Automatic control of hydraulic pumps with the ITH-APC-Control (Automatic Pressure Control)
- The ITH Autostrech was developed with the Center for Mechatronics and Automatisation ZEMA in Saarbrücken (Zentrum für Mechatronik und Automatisierungstechnik).
Digital input and management systems
ITH develops its own digital input and management systems. For example:
Documentation system for bolting technology
Documentation systems to manage and control all bolting applications
Transport and lifting devices
- Several high performance transport and lifting devices with capacities up to 350 kg and more
- Mounting systems, e.g. for Bolt Tensioning Cylinders on wind turbines or flange cover lifting devices
- Organization: ITH shop trolley systems
Test and calibration systems
ITH mobile test stands to test tension and torque tools on site, available for:
- Bolt Tensioning Cylinders

Synergy effects from a whole system supplier
The technical and economical efficiency of a bolted connection depend on 4 major factors:
- Design elements
- Fasteners
- Bolting method (tensioning, torqueing, others)
- Assembly procedure
Being a whole system supplier only ITH Bolting Technology analyzes the whole picture. We have the capacity to configure the factors among each other for the best technical and most cost-effective solution for our business partners. One factor affects others positively: That is what we call technically efficient.
Overview all ITH industry solutions
ITH has developed several solutions for all industries like
- power generation inustries
- maritime and offshore
- machines and more
