A tensioner that makes the complex task of tightening foundation bolts easier and takes safety into consideration.
In a wind turbine assembly project, tightening the foundation bolts is one of the most complex tightening tasks. Dirt, misalignment, rust, control of elongation, and oil return speed complicate bolt tightening and can lead to assembly errors. The tensioners in this series are designed to facilitate the tightening of foundation bolts while also considering safety. 【Main Features】 ■ PD Tensioner ● Safety: Incorporates safety features similar to those of blade tensioners. ● Slim Design: The double-decker type guarantees high loads with limited radial clearance. ● Laser-etched Scale: Allows for easy control of elongation. ● Gearbox: The most reliable gearbox, enabling the fastest oil return to avoid unnecessary time wastage. ● Optimized Design: Achieves high loads with a small diameter, suitable for applications in limited space. ■ BR Tensioner ● An ideal solution for applications with significant bolt protrusion or unique thread types. ● Maximum stroke of 10-20mm. ● High-pressure quick connect coupler that does not require O-rings.
