Tube Boiler Installation - A 60m
boiler house, constructed from 350t of steelwork, only allowed for tight
manoeuvring space. The bogey was mounted on railway lines welded to the
steel hanging rods at the top of the boiler house. A crane moved the boiler
into position and the weight was transferred to the strand jacking system.
