Fundamentally new crane from Spierings
The basic principles of this new crane concept fully differ from that which has been produced by Spierings so far. The name of the model is SK387-AT3 City Boy and the main purpose - city contructions. From this set of requirements, the most noticeable is the single crane operator's cab, that also serves as driver's cab, as crane cab and as lift to reach the top of the tower for optimal view of the crane operator in every operating situation. Additional requirements were: more hook height by adding a third tower section, a maximum truck width of 2.5 mtrs and the possibility to luff up to 45˚.
