Milan, a lively town in the North of Italy and famous for its cathedral and shopping malls, is also one of the biggest Italian business areas. Every day, restructurings and redevelopments are taking place, as the space in the city center and even the metropolean area is tight and limited. Casella Autogrù was therefore tasked to take part in the redevelopment of a skyscraper complex in downtown Milan. The complex consists of seven tower building, mainly used for offices and being closely built together. Casella was instructed to place the air conditioning units on the roof top of a 18 floor skyscraper, therefore a lifting height of 70 meters was needed. Their choice for the task was the LTM 1350-6.1. The weight of the single units to be lifted was announced with 12.5 t.
