Only 3 rams like normal for the boom and dipper, it is all very complicated affair
I think the pins get shifted in the boom when you do heavier work
Hydraulics have come a long way
This is hydraulic over hydraulic so no electronics to give drama
But in pretty poor condition which doesn't help at all
I've never seen a boom/stick like that before. Must have four pistons on it! Would like to see it working. Nice pictures Paul, glad to see the ol'girl still earning her keep. .....Hippy
