The Excalibur gondola that failed was installed in 1994. Tower 4 that failed appears to have fractured a horizontal weld on the main support pipe column (from the photos it looks like a clean fracture) not a 'split' as reported. I can not remember but it is possible that tower 4 was one of the towers under vertical tension (up ward pull of the cable). We, engineers will be watching this investigation with interest. I have ridden this lift many, many times. The story below suggests that 'ice jacking' was responsible for thr tension failure of the weld.
