That job site was north Finland in winter. Upper than arctic circle. Ground was very icy and hard to dig. But fortunately we had Ruston. Hydraulic excavators are toys in these jobs. : )

ok, i understand. You need , for your big jobs, an 88 B series 4, the best !!. The transport cost is the same , but is another machine: stronger and bigger. Forget all Liebherr and Sennebogen, to phofisticated, also if are strong machines, the HD versions, not the crane versions. But have too much electronic components and i don't like Liebherr politically. Sennegogen use Cat engine, Liebherr his engines: when you have problem, expeciaally on the tier III and IV engine and over the 6 V cylinder engines, you are in difficult, forfamous service problems. Rest, all hyd circuits are Rexroth and winches are the same: Zolller. I prefer Sennebogen for this ( also Bauer prefer Sennebogen , why??!!!!! ). But, for your demolitions jobs and excavating jobs, old cable Bucyrus are the best: lower cost, lower fuel consume ( minus power ), better reability. Remain the transport cost that, for these machines , are difficult and expensive. A good compromise was the 65 D, hyd-mechanic, , same 38 B class, but more modern: hyd swing and travel with mechanical winches and torque converter drive : two levers: one , for accelerator, one for torque converter mechanical stator variable angle ( what you haven't on your 71 , because was disconnect ). Had a welding cab frame instead the casting , strong , casting frame as Bucyrus typicol. Is more faster that the 38 in excavating, three bars shoes excavator undercarriage; undercarriage frames with dismantling possibility. Was the precursor of the 5160 RB , 90 's years. Is good for your high reach demolition jobs Good job for your 71 RB tks
