AutoBolt - Complete System for Tightening of Bolts in WTG Flanges
AutoBolt is a complete system for fully automated tightening of bolts in WTG tower and hub/blade flanges in any pre-defined pattern. AutoBolt carries battery packs and a proprietary hydraulic pump eliminating the need for external power supply and external hydraulic pump.
The system also includes a control system that documents the tightening process to individual bolt level, including registration of force/displacement curves and determination of achieved bolt pre-tension level using AI-based picture analysis.
Modular Design
AutoBolt consists of 5 modules that are easily assembled with no tools needed:
- Left Caterpillar propulsion module
- Right Caterpillar propulsion module
- Main Unit which carries Elongation Tool as well as the Control Unit with wireless link to control tablet
- Proprietary ADMEDE Hydraulic Pump Unit with 2,000 bar capacity
- Two interchangable Battery Packs
