UK-based City Lifting lifted the 4t units at a radius of 54m using only the crane’s main boom, as the limited space in central London prevented the company from rigging a fly jib.
To reach the site of the children’s hospital the crane also had to navigate a hole which had been dug in the adjoining access road.
The lifts, which represented the first time City Lifting had used its GMK6300L, were completed in a day.
