Old Hitachi C60 Railway Crane
I'm sharing photos taken in Argentina of an old railway crane used for maintenance. The crane has a fixed boom, several drums for steel cables, slewing pulleys, and a gear that allows the superstructure to rotate.
The frame shows the identification C.60 and the inscription "T. 92,000 Kgs." According to railway records, it corresponds to a Hitachi GV400, of Japanese origin. The crane was reportedly in service at the General Guido station. It is now abandoned.
This type of crane was used to rerail railcars, lift heavy components, and perform railway maintenance work.

Help moving this bandsaw? Tips in lowering it? 600lbs.
Bandsaw is 86" tall. Garage is 78". Last two times to move it we used a fridge dolly and 4 guys. Leaned over a lot to clear the garage and muscled it in side. I then ran and lowered the garage door to get it to close.
Using a tool to lean it over 45 degrees isnt enough, still too tall.
Any other ideas aside from just 4 strong guys again? If we did strong guy I'd ratchet strap a 4x4 somewhere to help. The cast iron top will be removed to cut 120lbs.
If I can just slowly lower onto a pallet I'd be fine. I'd figure out how to raise it up later.
Thought about strapping two 800lbs furniture dollies too BUT the tricky part is lowering and not dropping it and or crushing someone.

Mini excavator
Good evening everyone,
I’m sure most of you have seen those mini excavators on FB marketplace for 4-5k no brand name as what I’m seeing. Anyway, I have to friends of mine that have bought them and they have quit working pretty much as soon as they got them. Just wondering have anyone had trouble with them and what did you do?
Both have trouble staying running.

Advice on Selling Old Cat Generator?
I have a 1973 Caterpillar D398 750kva in a warehouse that I want to sell. I don't know much about it, but it was used as a backup for a municipal water station, so likely has few hours.
I can't confirm if, or how well it works but I get the impression that it would not take much to get it going.
My question is, whether it is worth paying a technician to come out, check it out, try to get it going, etc., or just sell it "as is"?
What kind of reports/analysis would a potential buyer want in order to pay more that as is value?
It is an impressive looking machine, but any dealers I have contacted have said that it is too old for them.

Bobcat E20 Help -Tilted locked out of controls.
***SOLVED! When I tilted back I must have kicked the control patter selector (which is oddly located by your heel when seated) It was maybe five degrees off the CAT control setting. This allowed only the functions that were the same between CAT and SAE to work. So the tilt alarm was unrelated to the issue. Thanks again for all your help.***
Hello all. I'm renting this bobcat e20 and it gave a tilt alarm and locked me out of the controls. I could easily get myself out of this if I could just USE THE CONTROLS. Does anyone know of an override? And is this a safety feature or am I experiencing something else entirely.
PS The User Manual is $60 so I thought I'd ask you good people first. Thanks in advance.
***Forgot to mention: the tracks still work and the cab still rotates (left controller left and right) and the bucket can still go in and out (right controller) but the boom and arm itself is not moving.

Why standard truck frames fail when you mount a 100-ton rotator without secondary subframe FEA.
Had a contractor ask me last week if they could just buy a bare 100-ton rotator superstructure and weld it directly onto a standard heavy-duty dump truck chassis they had lying around. I almost choked on my coffee.
A lot of guys in fleet management think a truck chassis is just a solid block of steel. But when you are rotating a 100-ton load sideways with outriggers fully extended, the torsional stress on a C-channel frame is absolutely brutal. If you do basic static structural analysis, you'll see the stress concentration near the rear tandem axles spikes way past the yield strength of standard St 37 structural steel if there is no continuous, reinforced subframe.
If you weld it directly or use poorly designed mounting plates, you will twist the frame rails into a pretzel on the very first heavy lift.
For heavy-duty rotators, you absolutely must run full finite element method (FEM) modeling in software like ANSYS. We have to design an integrated, high-strength subframe that runs the entire length of the chassis to distribute that localized bending moment.
Also, standard gear pumps will kill you here. Trying to slew a heavy load with manual on/off valves makes the boom whip. You need load-sensing proportional valves (LUDV) to keep that multi-action swing smooth.
For the operators here: What's the sketchiest home-made rotator setup you've ever seen on a job site, and did the frame survive?
