Yep, hydraulics drag a 200kg weight up to 8 foot and drop it at speed, highly dangerous, this precise machine has already claimed one finger when a friend left his hand on top of a post and someone else released it.
Yep this one is an old one, so it has two screw link arms to adjust both planes
An impressive and dangerous looking bit of kit.
Is it hydraulically driven?
I'm guessing you have to set up vertical/square for each post?
Got to be much easier than using a drivall.
