Apart from the first attempts to rig 60 m hub height wind turbines by using telescopic 300 toner (Demag AC 300, for instance), at the beginning of this century, most of the leading role in the installation of wind farms in Europe, ran on the side of the large lattice boom cranes on crawlers. The

What the designers of the Demag CC 2800 did not guess in 1998, is that it would undoubtedly be the most successful lattice boom model of the brand, with about 400 units sold. The secret of its success, has surely been its surprising versatility. The modular boom system of this 600 toner has allowed a

 Would you like a challenge?. What crane would you have used to mount each wind turbine model during the first decade of this century? Here’s my proposal (*):

When the first AC 205 all terrain mobile crane unit from the Demag factory in Wallerscheid (Germany), came out in 1994, there was probably no reason to assume that the model would hardly change over the next two decades. It was revolutionary indeed, as it was the very first time that fifty meters length main

Should it be mandatory to get qualifications for operating mobile cranes anywhere?. In fact it should be… at least advisable. In most of occidental countries, the operator needs recognized qualifications to drive and operate a mobile crane. Similar to the mobile crane NVQ (National Vocational Qualification) in the UK, it is likely to find an equivalent assessment all over the world, but in some countries this code of practice is relatively new. In Spain for example, the official requirement to pass an exam (mobile crane test questions and answers) to get your mobile crane nvq (carnet de gruísta) is less than ten years old!

Going further into the safety standards to follow in the workplace by operators and users of mobile cranes, one might consider a few simple rules that in most cases ensure safe operation without risk to the integrity of individuals near the site of operation. Such simple concepts like: determination of stability of a mobile crane,
