The crane, believed to be a 500 tonne Krupp KMK 8500, (The design was a modified Gottwald AMK – the company was acquired by Krupp in 1988 this unit is possibly a 1989 model), was set up with a partially extended main boom and what looks like a full luffing jib, (The unit had up to 77 metres of luffing jib)to place an air conditioning unit onto the roof of a hotel in Via Franchetti, close to Milan’s Central Station.

The apartments on the 10th floor were damaged and although occupied at the time by a family with children they were frightened but unhurt.

Tenants have been evacuated from the building until the crane is removed and the buildings declared safe.

Local reports suggest that a cable snapped, causing the jib to both collapse and twist, buckling the main boom.

However looking at the photographs it would seem that a supporting lug for the jib mast may have failed causing extreme side loads on the boom. What we do not know of course which happened first.
