Frequently asked questions
Which bolting tools are suitable for slewing bearings on cranes?
Hydraulic torque wrenches such as the DRS and electric high-torque wrenches such as the EDS are mainly used for slewing bearings on cranes. These tools enable precise, uniform and secure pre-tensioning of the bolt connections – even in confined space conditions and at high torques.
How does ITH ensure the quality and safety of the bolt connections?
ITH is setting standardized processes according to DIN ISO 9001, regular maintenance and calibration of tools as well as documentation of all bolting processes. Quality is ensured by trained specialist personnel, digital documentation systems and annual inspections – also directly on site at the customer’s premises if required.
Does ITH also offer individual advice and on-site service for crane projects?
Yes, ITH offers objective, technical advice on all bolting applications as well as a comprehensive on-site service. This includes inspections, maintenance and calibration of tools directly on the construction site or in operation. This provides customers with tailor-made solutions for their specific requirements.
What are the advantages of using ITH Bolting Technology for foundation bolt connections?
ITH bolting tools ensure maximum precision and traceability during the assembling and maintenance of foundation bolt connections. The tools are designed for large bolt diameters and high pre-load forces / preload and enable safe, efficient and documented assembling – even under difficult conditions.
Are the ITH bolting tools compatible with different crane models?
The ITH bolting tools have a modular design and can be adapted to different bolt sizes and crane models with different inserts and reaction arms. Customized versions are possible at any time, so that almost all common crane models can be covered.
How can I request a technical consultation or inspection?
You can request a consultation or inspection quickly and easily using the contact form on the ITH website or by telephone. A special service request form is available for maintenance and calibration, which you can conveniently fill out on your PC and send to ITH.
Is there an on-site service for inspections and technical advice?
ITH offers technical advice and optional inspections of bolt connections directly at the customer’s site.
