落物保护结构是在有坠落物体(如树木、岩石等)时，对司机提供适当保护的安全结构。

Falling-object protective structure (FOPS) can block objects (such as trees, rocks) so that it supplies protection for the operator.

可以通过使用隔板、防护网或防护墙、扶手系统、防摔网、保护平台或天棚结构等方式来提供防落物保护。

This can be accomplished by using toe boards, screens or brick guards; guard rails systems, nets, catch platforms, or canopy structure methods.

我想冒险一试，或许我们可以借助峭壁上凹入的孔穴保护，迅速通过这段糟糕的落物飞溅的地段。祈祷成功！

I want to risk it, to hurry from protected alcove to alcove, then make one mad dash through the worst of the falling projectiles-and pray.
