The teams working as one, seamlessly wrapping the lifting points in blankets, then in cling-film (yes, cling film!), in readiness for it being manoeuvred. On a hand signal, hand-over-hand, the clinking-clanking chains took up the slack, and the immensely heavy mast slowly lifted away from its plinth and was gently eased it down to the floor. A few signals, here and there, team members slipped a series of bogies under the now almost horizontal mast.
And rest, everyone! - Phew! That went well.
