Key Tasks

  • Torquing of aircraft wheel bolts and nuts with electronic torque and angle control
  • CMM-compliant torque sequence management with digital readout and data logging
  • Single-spindle nut runner for precise, controlled bolt-by-bolt torquing
  • Compatible with KUNZ UAS 

Overview

The KUNZ UTT NGtronic® Universal Torque Tool is an electronic torquing solution for aircraft wheel assembly and disassembly, delivering automatic torque and angle control with digital readout and integrated data logging.

As a single-spindle nut runner, the UTT provides precise, bolt-by-bolt torquing in strict accordance with the CMM-required sequence. The built-in software guides the operator step by step through the torque process, preventing sequence errors and ensuring full traceability. Work orders can be retrieved via barcode scanner or RFID card.

The UTT is fully compatible with the KUNZ UAS and can also be paired with third-party assembly stands. All torque data integrates with the KUNZ Wheel & Brake Shop Software, and remote maintenance support is available for fast issue resolution.

Main Benefits

  • Electronic torque and angle control – consistent, repeatable and error-free torquing
  • Step-by-step CMM guidance prevents incorrect torque sequences
  • Digital readout and full data logging for process traceability and documentation
  • Barcode scanner and RFID card support for work order retrieval
  • Compatible with KUNZ UAS
  • Works with KUNZ Wheel & Brake Shop Software
  • Remote maintenance support for fast issue resolution and software updates
  • Hydraulic lift enables effortless repositioning to the next bolt

Controlled, Documented Torquing – Bolt by Bolt

The KUNZ UTT NGtronic® delivers the precision and process reliability that modern aircraft wheel maintenance demands. Its electronic torque and angle control system ensures that every bolt is tightened to the correct specification, in the correct sequence, every time.

The integrated step-by-step CMM guidance eliminates the risk of incorrect torque sequences, while the digital readout and data logging provide a complete, auditable record of every assembly operation.

It emits significantly less vibration than conventional impact wrenches, resulting in smoother handling and better control. At the same time, it ensures less strain on the operator and nuts, reducing fatigue and minimizing wear on components. Additionally, the KUNZ UTT generates less carbon dust, contributing to a cleaner and safer working environment.

Flexible Integration – KUNZ UAS and Beyond

The KUNZ UTT NGtronic® is designed to integrate seamlessly with the KUNZ UAS workstation, but its flexibility extends further. It can equally be paired with third-party assembly stands, making it a versatile investment for workshops that already have existing equipment.

Whether used as part of a complete KUNZ wheel assembly line or as a standalone torquing upgrade, the UTT NGtronic® delivers the same level of precision, documentation and process safety.

KUNZ Wheel & Brake Shop Software Integration:

All torque data recorded by the UTT NGtronic® can be directly exported to and managed within the KUNZ Wheel & Brake Shop Software, providing a seamless end-to-end documentation solution for the complete wheel maintenance process.
 

Remote Maintenance Support:

KUNZ offers remote maintenance support for fast technical assistance and software updates, minimising system downtime.
