no worries man. I service these machines daily so I just have first hand experience is all... As far as when they need to drill I'm not to sure, my guess is that it's the depth required for the piles that determines what type of machine will be used, normally (depending on where you are) the top 50 feet or so of earth is pretty soft so a small vibro is suitable for driving, any deeper and maybe you'd pull out the drill.
I think these steel sheets are for retention before excavating for large-scale building of foundations. They opened up the ground later.
In the Netherlands, where houses need piles even when built only a short depth into the ground, they use larger, solid piles and they hammer them in with a weight that is raised and dropped repeatedly. That's what I saw there many years ago, anyway. So this kind of equipment is at the lighter end of the scale, then, isn't it?
yes it is, from the looks of the video anyway, there are however all kinds of different vibros out there, traditionally they are lifted by a crane and they rely on their own weight plus the vibration to drive the sheets, the type in this video is a very new and innovative design. Traditional style vibros come in all different sizes from tiny ones (the size of the hood of a car) right up to huge ones (Bigger than a transport truck)
Perhaps there is some continuous pressure, but pulsed. Vibration makes use of the fact that there is water present lower down because it is by a river.
The machine is actually a drill rig, it has a vertical mast mounted on hydraulic cylinder out front of the machine, normally it would have a drill on the mast but some models like this one have a vibro retrofitted to the mast. They use a winching system knows as a crowd to pull down on the attachment in this case the vibro and force the piles into the ground. If it where a drill, the crowd would pull on the drill head and force the auger into the ground,
I hate to have misled people with my statements about what appears in these videos.I think it's true to say, then, that it's a drill rig being used as part of a pile driver. Maybe in firmer ground drilling would be necessary?

It is hitting it, or pressing it?
