This was a large rig! Although the scale is roughly the same as our other Pile Driving Rig models (due to the size of the chain treads), this rig has a much higher reach and a serious support arm! The real rig isn't designed to fold, so this one isn't either. However we did develop two attachments for the builder to choose between - a hammer and a drill. And we incorporated a linear actuator that can precisely control the position of the leader.
