Simulation may explain Science Tower lift failure


INVESTIGATORS SEEKING the cause of last month's embarrassing lift failure at Glasgow's troubled Science Centre Tower are to stage a simulation of events preceding the debacle.

Ten visitors were trapped for fi ve hours half way up the 105m high rotating structure nearly three weeks ago, and were fi nally rescued when firefi ghters cut through the tower's aluminium skin (NCE 3 February).

Early investigations revealed that a power supply cable had been severed, cutting off power to the external lifts.

Swedish manufacturer Alimak built the special stainless steel rack and pinion lifts for the tower. It launched an immediate investigation, but although it was easy to identify what had happened, establishing the failure mechanism has turned out to be more difficult.

Initial investigations are now complete, ' a Glasgow Science Centre spokeswoman said.

'A detailed analysis has been launched, which will include a simulation of the operating conditions immediately before the failure occurred.

'We expect a full report in about two weeks.' The tower will remain closed until the report is published.

Since the tower opened 40 months ago it has been closed for 30 months after a series of defects.
