Tentec, a leading UK designer and manufacturer of bolt tightening equipment for wind turbines, recently exhibited its Aero range of bolt tensioning tools for wind turbines at AWEA’s WINDPOWER 2010. The complete series was on display, with Tentec being the only company in the world to offer a full load, positive stop safety feature on the entire range of wind equipment. The new elliptical tool, designed for foundation tooling where there are space restrictions and accessibility problems, is the latest tool to be launched with this feature.
Overstroke protection is one of the most important factors to consider when assessing bolt tensioning tools. Without this feature engineers are prone to keep stretching, and this can result in the failure of seals and other parts. More importantly, any failure could create a critical safety hazard. Once this occurs the operation has to be stopped as, at a minimum, the seals have to be replaced, along with other work that needs to be carried out to rectify any further damage. This results in costly downtime that could be crucial for completing profitable job on time and within budget. Tentec’s in-house engineers have designed this unique full load, positive mechanical stop system so that just fractions of an inch over the required extension and engineers will hit a mechanical stop and stretching will cease.
As well as the range bolt tensioning tools for wind turbines, Tentec offers a choice of electric driven high pressure pump units that can generate pressures of up to 2000 bar. For more information call + 44 (0) 121 524 1990, e-mail sales@tentec.net, or go to www.tentec.net.
