Wind Blade Mould Hinge System
Red Maple wind blade turnover system is the choice of industry leaders, proven on more than 130 moulds worldwide. The system provides a convenient and safe opening and closing system with an opening/closing time of 2-3 minutes.
The full closed loop arm angle alignment control system avoids any risk of mould twisting with a smooth variable speed operation and a super-slow final closing action.
The final closing motion is totally vertical for the last 120mm allowing a free floating upper mould for perfect alignment. This system assures excellent cost/performance ratio and is available with zero lead time.
PROVEN TECHNOLOGY
Many of the established wind turbine blade manufactures use this model of the turnover system, and this system is used on approximately 40% of all wind turbine blade moulds that have been produced.
Red Maple, in conjunction with ‘Power Hinge Inc’ have sold in excess of 80 moulds with the hydraulic closing system, and when combined with over 130 mould installations, 20,000 wind turbine blades have been assembled using this hydraulic closing system since 2003.
