Well if you are going to charge a one megawatt hour capacity battery pack in one hour, you need one megawatt of supply. If you want to do it in 2 hours you need 500 kilowatts. And I'm not even figuring on losses. Basically a 1200 amp 480 volt three phase circuit to every charger. And the damn chargers must have a transformer in them, so now you have a problem with "low lagging power factor". And they also have to have rectification to turn the AC into DC. so there is going to be a problem with harmonics. Just like the problems with harmonics we are having in the plants now that all the motors are on VFDs. It distorts the sign wave all to hell. Large data centers have the same problem because of the rectification in the computer power supplies. It's a dam expensive problem to fix. And it's not a problem that is contained in your facility. It gets so bad that it affects the power company's distribution circuits. You might be causing a harmonic problem, and I'm 1/4 mile down the road, and all of a sudden my electric motors start overheating. There are just too many problems, and we are talking on a huge scale

I'm really surprised they got enough cooling under the hood of a RD800 for a 3412. Every 3412 I've ever seen has a huge radiator

Yeah North American Engines had a 149 powered generator in a trailer and it was pretty loud, but I didn't ever have to be inside with it running. Those two 16V at Philly Police Headquarters (Roundhouse) were in sea containers and being inside with them running made it all so much more intense. Did you ever run a DA sander and it makes your hand itch because it's doing nerve damage? Well that is the same itch you feel in your teeth inside that sea can with a 16V running in it. But that isn't the point. The point is that those electric class-8 trucks need that kind of power to charge. If you wanted to set up a generator powered charging station, you'd need a 16v92 powered generator to run it. That damn tesla Semi has a roughly one megawatt-hour battery pack. So to charge it in one hour you will need a one megawatt supply. Have a location that you need 10 charging points, and you need a 10 megawatt supply, a truck stop will need their own peaker plant. It's just totally unworkable

That was from the 16v92 Detroit Diesel running under load. Have you ever been near one running? They make some serious noise 1t 1800RPM under load no matter if they are driving a generator, a pump or whatever And yeah I work on medium voltage switchgear now and again too. Most of the larger plants here have 69KV primary power dropping down to 12.5KV on the secondary side of padmount, and then down to 277/480 close to where the power is utilized. I've never felt it, and I hope I never do

I took their 4 axle autocar and a 4 axle Rogers to Parkersburg WV to pick up a Tadano Mantis back back in about 1986. Not too long after leaving Parkersburg I was using the jakes and the elbow blew out right below the muffler. Talk about screaming. By the time I got home my ears rang for a week

I just checked, it had a Cat 3412 engine in it. The story is that they wanted Carter Machinery to install it, and Carter refused, so they did it in their own shop. Carter Machinery is a super huge Cat dealer in that area

It's adjustable, if it's like the ones I used it's hydraulic. It probably uses the Fifth wheel that takes the large pin. Or like some I've pulled the pins were swappable. I think that orange DM800 that has the Bethlehem Steel on the door has the big fifth wheel on it, or at least it did when it worked at the mill. McHugh sometimes used one of these Cline Prime Movers that they built from off road dumps to pull trailers like that with the tall gooseneck

Yeah I remember Trap Rock. They ran all yellow heavy spec DMs, didn't they? I never knew they had a Mack Switcher. I'll bet JC McHugh would know what happened to it. That's pretty local to him. He's in the old Strick Trailer plant in Fairless Hills Pa. Railroad equipment is his business and he's into the antiques https://www.mchughlocomotive.com/

Famous truck in the Kentucky Coalfields. Crazy Big Cat power. I seem to remember it being a 3500 series industrial. The last I heard it was in pieces in MMI's yard Edit, it's a 3412 cat

6-71 Detroit powered. It might have even been a 2 valve, I can't remember. I think it was 9 1/2 feet wide with the outside tires on

Pepsi Sacramento required upgrades to the utility substation and powerline to be built to run their chargers, and they had to install a Tesla Megapack on the ground. Those Megapacks are 1 Million dollars installed a couple years ago. The project took 3 years. Here is Pitt-Ohio's experience with electric trucks

If they are going to electrify at all, the only way it's going to work is diesel-electric hybrid. People have the impression that they can go to Home Depot and buy electrical supplies, amd find an empty space in their breaker panel and that would be enough to charge an electric class-8 truck. In reality for even a small fleet you are going to need a 1,000 KVA pad mount transformer installed at your facility. If you wanted one next week, you need to get a time machine and go back to the year 2020 and start planning. The customer side of that transformer would be a 1,204 amp, 480 volt, three phase circuit. Just to put it in perspective, I've worked on emergency generators for the City of Philadelphia that were rated One Megawatt. They were powered by a 16v92 twin turbo 2 stroke Detroit. Roughly 1,500 horsepower. If you were in the enclosure doing tests and you had it under load you could feel your bones vibrating and after like 5 minutes your teeth started to itch. Most places don't even have that much power coming down the street, you are talking about having to do upgrades all the way back to the substation. And lots of substations can't handle it and will need upgrades. Pepsi Sacramento's substation had to be upgraded to charge those Teslas. It took them 3 years to get the power. I could go on and on with the problems. The six pulse rectification to turn the AC into DC creates 5th and 7th harmonics on the powerlines that doesn't end at the property line, it effects other power company customers. The people making these mandates and regulations are way way out of their league. BTW here is what the American Trucking Association has to say about it

I haven't followed up on that much lately. I would imagine weight, and getting enough power into the facilities to charge them is a problem. It's not like you can just call up Billy Bob's electric and get him to install a 1,000KVA transformer to supply the chargers. That requires long term planning and in a lot of places 8 figure budgets

There is a place by Pottsville that handles all kinds of brakes for industrial applications. They have all kinds of odd stuff there, and do rebuilding of hydraulic parts, make control cables etc. They might be able to help get those hydraulic parts for that juice brake B85. They are in an old bakery building on if I remember right Bakery road. They got me some stuff for my juice brake Lancer Boss forklift that was made in Germany. I'll have to see if I can find the name of the place Found It https://www.airbrakeandpower.com/ Air Brake & Power Equipment Company, LLC 1048 Bakery Rd, Pottsville, PA 17901, USA

Years ago I had a single axle IH wrecker with the cab burned off of it. I got an R model with a broken trunnion. The R model frame slid right inside the IH frame. Spme minor shimming and it bolted together so nice with lots of overlap. I was tempted to not even weld it, but I did weld it some. That saved me so much work. If that hadn't worked out I would have had to change all the mounts for the crane and the body to make it fit the R Model Frame. Not to mention putting all the single axle suspension under it. I think I probably saved a weeks worth of work

You need ratios considerably lower than that. Is it a 5 speed truck? A set out of a truck with a big overdrive like a Mack 2050 trans or a 2090. Probably where you want to be is around something in the 5s or more

,Yeah the frame on your truck really looked good especially. considering its age. Joe Capecci had some triple frame B Models behind his place on Church St near Sepviva. One had the L cab on it and he was still running it in about 1990. There were some without anything on the back because Liberty Concrete actually owned all the barrels and Joe owned the trucks. I'm not sure where they ended up when he sold the property. I'm no youngster either. I was climbing down off of a machine and my foot caught the base of a pump that was mounted to the floor. I felt a pop, and it felt like I stepped on a spike or something but there was nothing in my boot. I tried to walk up a staircase to get to the other side of the machine and I couldn't do it. Turns out I completely tore my Achilles tendon so now I hobble like an old man. So mechanical projects are tough on me too. Be nice if I could hare a decent kid lol

Are you going to ever use it on the highway? Here in the anthracite region if it wasn't going to see the road it would just get welded up and even the fishplates welded on 😄. Burn it in with 6011, and cap it with some 7018 passes. I'm guessing you have 3.87 ratios. What do you expect to do with this truck. How fast does it have to run. you can find some really low ratios out of something with an overdrive trans, and end up with a truck that tops out at like 35mph but will pull anything

I remember MACK Transportation in Philly. Near the Port Richmond area but to the west of I-95. They had a big illuminated sign you could see from 95. A little off topic, but I think JC McHugh still has this Mack locomotive, I forget the story about them, I kind of remember Mack Truck bought them and repowered them and refurbished them at Allentown. I might be remembering wrong though

Yeah, well I go back just shy of 50 years doing this full time and I remember getting them out and saving them or at least most of them, but older trucks that are run here in the northeast, and especially double frame trucks can be really stuck. But shop labor worth a lot of money anymore, so I just figure on buying new bolts if I have to do one. I'm up in Hazleton Pa and when you remove a mack trunnion in a double frame truck, bolts are usually the least of your worries, the damn rust jacking is your big worry.

Those are all "body bound bolts" They have a shank that is larger than the threads. When you install them you ream the hole to tightly fit the shank of the bolt. That way the bolt also acts like a dowl pin. They don't come out easy. You are not going to spin the bolts. You have to spin the nuts off and then drive them out. Most times they get damaged while being driven out. When you get new bolts the shank diameter and shank length are important. There are larger diameter shanks available because if you are swapping parts around you will need to ream the holes oversized and instal the larger OD bolts. Being you are using the same parts on the same frame rails, you won't have to ream the holes unless something gets damaged. I swear I met you. Did you stop around Eugene Evans shop with Tom Zacny? Or maybe with Thackray or Joe Capecci?

Nice truck. Where is it located? The barn on 611 & Street Rd?
