Externally
Located Blast and Paint Booth / Oven Combination
Our client had recently purchased a large tower crane
hire company to compliment their concrete Slip forming service.
Having purchased other facilities from Airblast previously the client
asked us to design a facility for their new site in Sheffield which
would allow them to blast clean and re-paint tower crane sections
as efficiently as possible. These large lattice structures weighing
up to 13 tonne each would prove to be a challenge.

It occurred to us that this facility should be made
up of an in-line Blast then Paint / Bake units. Running through
the facility and 15mt outside both ends would be a rail track carrying
our pneumatically powered bogy. The method of operation would be;
a crane section was loaded on the bogy positioned outside the blast
room. This would then be driven into the blast room. This section
would be equipped with a full recover floor, central pit for blasting
the underside of the sections, two blast machines, reverse jet dust
extraction and high level access platforms. Once blasted the sections
would be driven out of the blast section and on into the spray section.
Painting was to be done by means of a Graco air assisted airless
system located remotely in a paint mix room. Once painting was completed
the facility would be turned over to bake mode.
As well as the two main elements of this facility we were asked
to include a 500cfm compressor package in its own compressor house
and a plant room incorporating the blast machines, grit elevator
and paint mix room.
Airblast completed the whole installation including all plant, portal
framed building and civils in six weeks. From commencing design
to handover took approximately ten weeks.
