CAUGHT IN A WEB

News

A redundant 135m tall concrete chimney at Corus's Port Talbot works is being nibbled down to ground level by a giant 'demolition spider'. Developed by tall structures specialist Bierrum in conjunction with Pendrich Height Services, the spider has six extendable legs supporting a hydraulic breaker tool, and is winched into position without the need for a crane. Bierrum says the chimney, which tapers from 7m diameter at the top to 10m diameter at the base, is losing height at a rate of up to 2.5m a day - twice that possible with traditional hand-held breakers. The £250,000, 16-week contract is due to finish by the end of next month.
