It's suspected a cable broke, sending the car careening until it hit a pylon and the fell to the ground.

据推测，事故原因是缆绳断裂，导致车厢倾斜，撞到电塔并掉落到地上。

" I can see it would be a terrible thing for Switzerland if a cable broke" .

“我认为，如果电缆断了，对瑞士来说将是一件可怕的事情”。

In November, only 3 months after the first cable broke at Tower 4, a second one failed.

11 月，即 4 号塔第一根电缆断裂仅 3 个月后，第二根电缆也发生故障。

NSF scientists believed the cables could deal with the added pressure and weight they were carrying. But on November 6, the main cable broke.

美国国家科学基金会的科学家认为，这些电缆能够承受额外的压力和重量。但11月6日，主电缆断了。

However, if the cable broke — releasing its tension — springs behind the levers would force them outwards into grooves in the elevator rails, those rails were then forced against the shaft walls, quickly arresting any cars fall.

然而，如果缆绳断裂——释放拉力——杠杆后面的弹簧就会迫使杠杆向外进入电梯轨道的凹槽，然后这些轨道就会被压在井壁上，迅速阻止任何坠落的电梯轿厢。

It wouldn't be surprising at all to find out that the peak stress in the remaining cables on Tower 4 actually did exceed their rated strength when that first and second cable broke, even if only for an instant.

当第一根和第二根电缆断裂时， 4 号塔上剩余电缆的峰值应力实际上超过了它们的额定强度，即使只是一瞬间， 这一点也不奇怪。
