The complex encompasses seven tower buildings and Casella was contracted to place the air conditioning units on the roof top of the 18-floor high-rise, which required a lifting height of 70m.
With a narrow timeframe while city centre roads were temporarily closed for the duration of the lift, Casella’s Crane operator Claudio Lozza lifted the units weighing 12.5t each with a radius of 45m.
Limited space in the city center was the main hurdle as the 350t crane, with 100t ballast, had to be positioned on the centre of the road with outriggers placed half on the road an half on the sidewalk on two different heights.
The Y-guying system was used to support the telescopic boom with the lattice jib attached, a TYVEN configuration. The LTM 1350-6.1 is the smallest crane featuring a Y-guying system.
“The Y-guying system allowed us to benefit from incredible load capacities while guaranteeing reduced dimensions – this was the crucial point during this job," said crane operator Claudio Lozza.
“It’s always challenging to operate in metropolitan areas, no matter if you are in the open field, in one of the many industrial plants or in the city center – always a question of timing, traffic and limited space. But with this extrodinary crane, handling gets easy and the work is fun.”
