Are you talking about the plate between the weight and the post or the weight itself.Our banger has a 12mm bash plate, soon got destroyed and replaced with thicker metal
I made a drop hammer piling rig for a job knocking 300mm steel casings in the ground 3 m deep and made the weight out of an empty oxygen cylinder cut the top off welded the end of a hydraulic ram on for the lifting eye then melted lead into it.
Now that weighed just over a tonne and by god that could shove them in for such a small weight
It was made from a FLT mast so when up to 3 meters but because we where bottom driving the deeper the pile the more dropHow far was the the drop, derrick height?
Force = Mass x Acceleration
Hydraulic legs are great, I've go a Protech with them, great for rough ground, can lift up to slide the boom out, then plum.
The legs on the Protechgenerator are on the sliding carriage then? I'm sure the ones on the Bryce are on the main frame but I'll have to go back and look. ie drop the legs then side shift and power out to the rear as required.
Bob c and gav0994, those machines look good. Do you have more pics and some dimensions? Did you have side shift and and rearwards movement. (Not sure what you call that!)
I was considering building a post knocker as a winter project and priced up a 200kg solid round bar 380mm diameter 205mm long and it was £300+vat with local steel supplier
