COST

Major cost reduction for both construction and service bolt tightening tasks due to significantly reduced time consumption, improved quality, attractive equipment rental model, and full freedom in tower design.

SPEED

Technology significantly reduces time consumption for tighening of bolts in WTG flanges removing this process from the critical path in the WTG erection processes

QUALITY

Technology ensures and documents that bolts have been tightened according to spec., including pattern and achieved clamping force.

HEALTH AND SAFETY

Technology removes manual labor from the bolt tightening process and is easily installed by two people in less than 5 minutes without any heavy lifts.

Autonomous Process

AutoBolt is mounted on the flange in less than 5 minutes and will after initiation by the operator perform tightening of all bolts in a fully autonomous process according to a pre-defined tightening schedule 

Freedom of Tower Design

AutoBolt runs on the nuts and has no contact to the flange. This secures full freedom in the design and optimization of WTG towers, including reduction of flange widths and thicknesses.

Faster Installation

  The fully automated process for tightening of bolts elimates manual labour and reduces time consumption significantly. Time consumption per bolt 20-40 seconds. Typical time consumption per flange 1-1½ hours.

Improved HSE

The elimination of the manual tightening process removes the risk for installers of white finger syndrome, hand and finger injuries, injuries caused by repetitive lifting of heavy material, and accidents caused by leaks of hydraulic oil from hi-pressure hydraulic hoses.

Cost Savings

Significant cost savings due to faster installation processes with reduced crane time and fewer personnel man-hours, reduced material consumption in flanges and bolts, and elimination of need for re-tightening of bolts during WTG lifetime.

Automatic Data Collection

  AutoBolt eliminates the need for Smart Tools. Fully independent from the tool and pump brand, AutoBolt collects all relevant data from the tightening process, including bolt-ID, applied hydraulic pressure, and angular turn-of-the-nut, and stores these in an encrypted documentation file while at the same time removing any risk of human error.
