The derricks have been specifically designed for installation of towers, poles and vertical structures and they are manufactured in tubular welded light aluminium alloy reticular structures. They are available in sections of different lengths to be connected to reach the required total length. The derricks have swivel head and swivel base and they are pre-set for external rope passage.
To choose the correct derrick it is necessary to specify :
1.derricks total length required
2.derricks working position (see the working pictures)
3.lifting load required “C”
1. Check in the total capacity required according to the lifting tackle type to be used and the “C” lifting load required.
2. Identify the correct derrick type according to the total capacity, the length and the working position required.
Special design derricks are supplied on demand (e.g.in case of not standard lengths, internal rope passage with special suspended working position attachment etc.)
