INSTALLATION & SERVICING APPLICATIONS WIND ENERGY CATALOGUE Wind turbines are not always conveniently located. Reliability of bolting is critical to avoid down-time. It is harder to control joint integrity when on-site in mountains and at sea, in extremes of heat and cold, wet and dry. Norbar tools are designed to be joint insensitive, able to deliver the correct degree of bolt pre-load despite variances in joint rate between fastenings. The Norbar “intelligent joint sensing” technology controls motor speed, reducing load variation due to temperature induced movement in steelwork. Wind turbine design does not always lend itself to easy bolting applications. Curved surfaces, tight spaces and working at height all create challenges. Auditing to identify trends and service intervals can save money and avoid disaster. The unique audit mode of our EvoTorque® corded and cordless models allows a very slight bolt movement to be analysed and the status of the fastener recorded periodically to look for trends. As with manufacturing applications, sometimes the old way is the right way. A manual torque multiplier can be paired with a mechanical setting wench, or an electronic measuring wrench and the combined system calibrated to give traceability and even data capture when power tools are too large to fit. So, when you need help ensuring accurately installed threaded fasteners, call us. We are happy to help shoulder the load. enquiry@norbar.com | www.norbar.com 4
