The Latest On Herons Construction

Construction work has been continuing apace on London's Heron Tower site with the erection of the final one of the three tower cranes marking a very visible landmark in what is going on on site.

To set the trio up, Select Plant Hire supplied an Ainscough mobile crane which built the Comedil CTL630 crane which will be the larger of the cranes, and this in turn was used to put together the two Comedil CTL 400 cranes.

The Comedil CTL 400 cranes are capable of handling up to ten tonnes over a 40 metre radius whilst the Comedil CTL630 can lift 9 tonnes and has a 60 metre radius.

The cranes have already been built to their maximum free standing height and for extra stability once the structure gets underway they will be tethered to the 11, 17, 23, 29, and 35 floors of the building allowing them to be increased in height until they are capable of reaching the top of the building.

Due to the high number of cranes for such a small site they will also require a choreographer who will pre-check their movements against each other first to prevent any collisions and coordinate them like a high-rise ballet. Adding to the safety protection will be the additional feature of a computerised anti-collision system fitted to each of the cranes.

The primary role of the cranes will be to lift the large amounts of metal used in the structure from fabricated beams to the metal decking although visible structural work above the skyline won't begin until February or March 2009 making it the first of the new generation of skyscrapers to go up in the City of London but with the Pinnacle hot on its heels.
