Hailo Wind Systems

Partner for the International Wind Industry
 
hailo bladeliftAs the inventor of the aluminium ladder in Europe 50 years ago, it was Hailo that introduced ladders to wind turbine towers. So Hailo was on board right from the start of our industry. Its fall arresters and service lifts made important contributions to the development of the industry as the height of towers increased. Today, Hailo is a supplier of tower equipment that is installed all over the world and the company is present in all key markets, providing support to its customers. With its versatile range of products, Hailo offers solutions for all applications – onshore, offshore and in lattice towers.

The Helical Robotics Revolution

Bringing Industrial Automation to Wind Farms

helicalAbout three years ago, while I [Bruce] was sharing a drink with some friends, the evening’s conversation turned to wind turbines. One of the gentlemen at the table was managing a blade refurbishment project in Iowa, USA, that was behind schedule and over budget. His problem was related to the removal and re-installation of the blades. The project was constantly being held up by weather conditions unsuitable for crane operations, and the additional time delays and crane costs were threatening his project. Having experience with industrial robotics and composites, I asked him if it was possible to paint the blades in place and eliminate the crane entirely. ‘You’re nuts, that would never work!’ was his reply, and the next morning Helical Robotics was born. The following story outlines the solutions we have created to fix this sort of problem, and the machines that make it possible.

Ge:Net

Worldwide Wind Measurement with Turnkey Meteo Towers up to 140 Metres

ge-netWherever the installation of a wind turbine or an entire wind farm is planned, precise information about the area’s wind potential is imperative, not only in order to choose the most suitable turbines but also to calculate the expected energy yield as accurately as possible. Since the amount of energy generated by wind rises with the third square of the wind’s speed, even minor mistakes in estimating this speed have an extreme effect on the actual yield. Exact wind measurement directly on site may be the only answer. This is the speciality of Ge:Net GmbH from Clausthal, Germany.
