这段英文啥意思
The key was to use a pulley system that would magnify the applied force.So they rigged up a tent-shaped scaffold directly above the tip of the horizontal column,with pulleys suspended from the scaffolds apex.The idea was that as one end of the column rose,the base would roll across the ground on a trolley.
怎么都不看不懂.谁能给我讲讲

关键是使用一个能放大作用力的滑轮系统.因此,他们在横柱顶端的正上方搭建了一个帐篷形状的脚手架,滑轮就悬挂于脚手架顶端.其想法是,当柱子一端升起,触轮/滑接轮上的底座就会在地上翻滚.
再问：真的挺好的，那个base我一直不知道是啥，你翻译成底座。最后on the trolly怎么翻译？
再答：在触轮/滑接轮上的 trolley：小车，手推车；滑轮；触轮, 滑接轮
再问：翻译的很好。可是我还是看不懂。把柱子从横放，变成竖放，您能给我讲讲吗？画图更好。
