Hmmm, is this Infernal Machine on the russian ship in one of the freight rooms?
If so, you must get up to the balcony above these crates. I sometimes succeeded to climb as high as possible and then do a running jump to one of the opposite crates. However, you're supposed to move one of the crates into position and then whip over to the other one. Hope this helps, haven't been there for a long time
