The 525 crane may be considered the ultimate expression of the lifting moment/ weight ratio in the whole category. The use of materials with very high structural strength, the electronics, the advanced design systems and the possibility to use powerful and light joints, allow the crane to achieve the dual concept of lifting capacity and operating speed. The introduction of the PROGRESS electronic system has also made it possible to reach the highest safety standards. The model 525 has been successfully installed on crawler too, to operate on rough terrain and in places not accessible by trucks, such as the interior of some buildings.
