Spider notes
The real issue on steep slope work with a walking excavator is center of gravity.
That's why you see most of these operators digging uphill as with the boom downhill you use the boom to push your machine farther up hill and your counterweight is always uphill. The stabilizer legs have a spread of 17 ft. so it's pretty hard to turn one over. In soft dirt or slate rock slopes you often slide a few feet til your feet dig in good. A winch is rarely needed except on extreme 12 to 1 slopes or wet slopes.
Now is a good time to buy a walker/spider as with the economy slow a lot of equipment is getting sold cheap. A 1994 6000T series Menzi Muck with wrist sold in auction for $8000 in Houston Tx. last week. Had a failing pump but only 3200 hours.

All are good sources of equipment. Kaiser, Menzi Muck and Terex/Schaeff are the only three with parts dealers in the US. Given Terex's problems with buying too many companies too fast, so their dealer network is shaky, I'd stick with Kaiser or Menzi Muck. Both make superb machines. Most machines built prior to 2001 are not electronic which may limit some operational abilities but make them much simpler/cheaper to owner service. I'm impressed with the agility of the new machines but the over $200K price tags and the potential repair cost of on-board computer and sensors galore makes me wonder how long the electronics will last and what the future repair bills will be to replace all the gizmo's electronics that will prevent the owner from easily repairing them. I've got a 2002 Terex SCL 515 wheel loader that runs,turns, loader lifts but will not move one inch because the computer that controls the sensors is down and a new one is $5000 which is nut's for a pc that has less computing power than a cellphone. A Terex ripoff. So the machine sits till I can figure a way to bypass the wiring harness that goes into the computer. Any one out there that knows how to hotwire a Schaeff 515 speak up! Ren :beatsme
