Over the following three pages, Andrew Gaved looks at some of the latest applications and equipment developments in the UK demolition industry
Samsung customises in UK
SAMSUNG has developed a range of demolition attachments for its excavators over the past two years.
Senior sales manager Nick Rose says: 'High-reach, precision control and specific tools for dealing with different materials are required because the demolition process now is a highly specialised business. It has to be carried out with great care, with attention both to safety and to the need to sort and select debris.'
Such demands could not be met by the standard Korean front-end equipment, so Samsung decided to have its specialist attachments designed and built in the UK.
The first model to come into production was a long-reach version of the SE350LC-2 for Falcon Refurbishment and Demolition. The 35-tonne excavator, with a 19-m reach, has been in demand in the London area.
But when Falcon won a job to demolish three 11-storey blocks of flats, it needed an even longer reach, so a 55-tonne demolition version of the SE450 was designed, using a three-piece boom to give a vertical reach of 26 m. The rig also incorporates built-in spray nozzles for dust suppression.
Samsung reports that the combination of reach, low weight and dust suppression has given a high utilisation rate for the machine, which is often on cross- hire to other demolition specialists.
A new SE450 version with a further development of the three-piece boom is currently being designed for DSM demolition in Birmingham, but Samsung is keeping details of that one under wraps.
Contractor Andrew Connolly Demolition, which originally bought used Samsungs for its operations, bought Samsung's latest specialist demolition rigs from northern dealer Imaco when it needed bigger machines.
Owner Andrew Connolly says: 'They are extremely tough and reliable, and can take the severe punishment of the demolition and reclamation business.
'The drivers like them, too, because they are quiet and well-balanced and the controls are light and precise, which is important in selective demolition.'
Cardiff Arms cracker
CONTRACTOR John F Hunt has been using a new concrete cracker attachment from Italian manufacturer Verdelli on the £5.5 million demolition of Cardiff Arms Park.
The hydraulically driven 2.5 tonne PDI25R crusher rotates 360 degrees and pivots in as many directions as a bucket would. It has been used for primary demolition but effectively pulverises the concrete in its jaws.
John F Hunt's Group Plant Manager Robert Branagan said: 'It also allows good steel reclamation because the steel comes out of the jaws clean.'
The Essex-based specialist is now the UK agent for Verdelli attachments, which includes a range of crushers and a new design of pilebreakers for standard-sized square and circular piles.
