英語文法分析

某教材句子Passengers can feel their heavy boat being moved up and down while going
through the locks of the Three Gorges Dam.(旅客行經三峽大壩水閘之際,會感到沈重的船隻隨著水位上下移動)

請分析being是如何來的? 可否省略?
更新: 這個句子不能寫成Passengers can feel their heavy boat moved up and down while going
through the locks of the Three Gorges Dam嗎?

就像Mary bought a camera (which was) made in Japan. 直接省略which was 只剩 made
