The Typhoon+ multi-stage wind tensioner 14 July 2021

The new Typhoon+ hydraulic bolt tensioner from Nord-Lock Group has been developed to meet the technical and environmental demands of the wind energy market, where high bolt load and restricted access applications are common challenges.

Part of Nord-Lock Group, Boltight has developed a deep understanding of hydraulic bolt tensioning and is working hard to deploy the latest technology and advanced bolt tensioning solutions that permanently eliminate the risk of loose or over tightened bolts.

The robust Typhoon+ design ensures reliability during frequent and repeated use necessary on wind turbine projects, both on and offshore, for low radial clearance applications.

The new design offers many advantages. These include a fast automatic spring-return design using a single reaction allows a full return to zero stroke piston retraction, and removes the need for manual input; as well as improved seal technology - reduces seal changeouts and enhances general performance throughout the high cycle usage. Over stroke prevention also removes the possibility of over stroking the pistons. Internal fail safe technology keeps the tensioner on the bolt in the event of puller bar failure, ensuring user safety. 

Also featuring a high life cycle, the Typhoon+ has long service intervals, not restricted by a fixed number of cycles thanks to high grade material puller bar. It also requires low maintenance – due to an improved spring-loaded auto engagement gear driven nut rotating socket with a geared drive, and it's easy to use. A unique surface finish also provides long lasting protection in harsh environments.

Gavin Coopey, Boltight’s commercial and projects manager, said: "We're delighted to be launching this new solution to our overall product offering. We feel confident that the Typhoon+ will play a crucial role by making the process of using hydraulic bolt tensioners on wind turbine bolts much quicker, improve durability and reduce downtime.”
