Atlas Copco has been providing tensioning solutions for the wind industry since 2005. The initial tensioners were supplied to European manufacturers for the build of wind turbines within their facilities.
As time progressed the range expanded to Asia and then the rest of the world. Due to the demand from the manufacturing plant progressing to other sections of the industry, tensioners quickly started to be utilised within installation and service.
Relationships with many OEMS grew rapidly, due to working together on key applications and continuously delivering bespoke customized solutions for a litany of different applications within the industry.
Due to the typical application spacing within the wind industry, bolt tensioners are often small in diameter, with a taller height dimension. Depending on where the tensioner will be used on the turbine, bolt tensioners can range from single to multiple stacked load cells, allowing a smaller footprint but higher loads, typically working up to 95% yield of the bolt. With higher stack load cell requirements, puller bars were then designed for the tensioners, in order to be fully operational and fit for purpose.
