Cool Job. Where I use to work I oversaw the same job on 2, 797 haul trucks that hit frozen berms, at speed while loaded. We contracted the first to one local Cat dealer and I did the second in house. We built everything from scratch. Fortunately I had a young welder that the guys nicknamed "tick tick" who was fantastic at layout and cutting. I don’t remember the final numbers but I know we did all the structural repair, bumper, top deck substructure and re-machining the mounting face for the front strut that was torn off in the impact for less money than Cat wanted for the front bumper. The cutting and welding took less than a week. I had a really good crew.
When I first read this I wondered how two thousand, seven hundred and ninety seven haul trucks could be on the same job and hit the same thing. Took me a minute to figure it out, TWO model 797 haul trucks.
Is there an issue with alignment of the over all structure of the 797. My guess is the 797 took a glancing blow from the bridge, also I’m sure the bridge structure is like new except for some yellow paint scratches. I have seen pictures of cement bridge abutments hit head on by a locomotive pulling loaded BOx cars at moderate speed. The abutment appeared mostly undamaged.
@@Timothy-lb2vr On the other hand, I saw the photo of a semi that took out 12 wood guardrail posts + guardrail and then sheared off one column of a two-column bent under a bridge over the interstate. The driver had gone to sleep at the wheel. I saw the bridge about one month after the accident. The state had to replace the bent, the span, and the approach span. It took over 6 months to get the interstate and overhead bridge back open.
too many comments to make!, plasma explanation the best, chain hoist too cute, outsourcing fabrication NO FUN for anyone, magnets WOW, having a clone for measurements and to copy is a tremendous help. making me wait for part two no fun but understandable... 👍👍
I used to haul big machines in Africa. A new driver whacked sn overhead pedestrian bridge one destroyed a D11 and the bridge obviously. Pushed the cab 2 feet back and snapped a 3" kingpin on the gooseneck
Thanks for the explanation on the difference between cutting and gouging. You have the hands of a man who works for a living. Keep up the great content.
Whoa! What a mess! The owners are lucky they have you to put things back together again. Good that there was a sister machine for part sizes and shapes. Thanks for an excellent video.
That was awesome, thank you very much for uploading the video. You are a real tradesman and it’s a pleasure to see how you fabricated the components. Looking forward to part two. Watching from Perth Western Australia.😁👍👍🇦🇺
Kind of like fixing a plastic model that falls off the shelf. Ya just need a different type of glue and a real sharp Exacto knife! Love your work Greg, always spot on! Be safe, have fun!
Welded 28 years myself; I like your truck setup an especially the truck Crane with remote controls. An Wilton vise . For most work “Go big are Go Home “ your video s are are truly a Credit to the Trade !!! Thanks.
Recently discovered your page while deep into the RU-vid realm. I know very little about welding or metal work but these videos are fascinating! Amazing fabrication skills. Keep up the great work and viewing content!
Good grief, what a mess to have to deal with!.... would have loved to see and hear that impact. I hope you are getting paid very well for this one. Not many folks out there that could do a repair like this one. Please be careful with all that heavy stuff! Looking forward to seeing the finished results! I bet you'll be glad when this one is finished. Very tough job!
Awesome job buddy, I love that welding machine you own/using, we had 2 of those and a whole bunch of big 40 diesel machines where I retired from, Miller welders are the greatest ever. I own a Miller Bobcat for my farm and I run it to death. Keep making these great videos, I sure enjoy them, Thank you👍
It's amazing how much technology has advanced I can remember my dad using a wash tip on his cutting torch love your videos be safe and have a great day Sam ❤
Thanks for the rundown gouging/cutting. Only chance I had to run a plasma cutter was in a welding course 20 years ago. Some kid managed to erode two electrodes to worthless in one session. (that machine wasn't rated to drag the nozzle, it needed a standoff. He had been instructed on that point multiple times)
I have a Hypertherm 30 Air, and it does O.K., but damn your 110 is the hoss! For someone starting out, seeing all your gear is pretty intimidating just thinking about all the jobs you must have done and loads of hard work to get where you're at. I'm at the age where I'll prolly never get there, but it's cool to see someone who has. And you built all that capability purely on your skills and attention to detail. Awesome work! Thanks for being such an inspiration to the Repair & Maintenance community.
Yes a welder providing three phase and a huge plasma cutter must certainly give him an edge. Someone asked how long a job took the time it took was amazing. 👍🏼😁
I have a buddy whose over 70 owns his own welding service down here in SoCal He started welding when he was 17 I sent him this video he called me after watching it he said it was a real good video and that you know what your doing I've been jumping around watching your videos great content hope you get to work on or finish the 623 soon those will be good videos
Very interesting videos. I am now retired but I would have love to see your videos when I was a young man wondering what I would do for a living. I would have chosen your field of work. Every day it is something new and rewarding.
Those little "Pocket" Cahin hoists are such a great back savers and alinment tool. Everyody laughs when you show up with one of these but doesn't take long before they ask where you go it.
I use the same hoist, I have a trolley overhead in my race trailer for removing and installing the engine in the race car, as well as a trolley that goes out the side door to do the same if the car is outside next to the trailer. The hoist works flawless. Engine probably is maxing the weight rating but it has not failed yet.
This is the coolest repair ! We use those baby chain falls at work ( on tractor tugboats) for mechanical repairs-My late boss was from Holland. He called them”BBs” and they are INDISPENSABLE. THANK YOU Greg for sharing your outstanding content with us !
Beautiful as always. Maybe you can get them to drop a bucket full of gravel there for you so you can get rid of the pallets and pool of water that you are working in. Shouldn't take much and would make it so much better for you to work.
I have a feeling that when a job needs to be done that your name is at the top of the list. At our place I can tell who fixed our equipment by the weld and the finish.
Hey…. We’ve all been there. Wake up on a sunny Sunday morning and decide to take the belly scraper out for a leisurely drive with the family. Everything’s great then all of a sudden -BAAMMM!!! - the days plans were shoved down a shotgun barrel and shot to shit. Oh the humanity.
Those are nice self-loaders!, hate to see the repair bill on that!. I'm sure a structural engineer will have to access the concrete pillar!. Good luck repairing that scraper!.
@@alanrichardson1672 Well in my mind taking something that weighs tens of thousands of pounds that hit something at 60 mph and got twisted like a pretzel being repaired to operational by some guys is pretty impressive.
When I first found this channel I thought you were a rookie because everything you own is brand new. Ha ha was I wrong. I just want to go on a shopping spree like that.
I've been watching a few of your videos and started wondering why your voice sounded so familiar, and then I saw this video and realized why. I met you when I worked for JWT, and I worked there when this machine hit the Manning overpass.
"Ouch!", that must have been a hell of a collision 💥. Excellent job of rengineering, like those small magnetic plate clamps you used to hold the speed square on with 👍. Thanks for sharing
That front bumper bar seems to need an extrabracingt bar, coming out at 45 deg from the RHS chassis member, just before the front tyre, to form an angular strut!
Gonna be alot of squaring up to do on this one.🤞🤞The frame wasn't pulled to much.😪😪 Driver must of fell asleep behind the wheel. Sure hope he or she has nice insurance or a fat bank account. This is gonna hurt the wallet no doubt about that.
What a shame for a new machine like that to be butchered by a careless driver. Man that's a headache and a half for an owner of such an insanely expensive machine. Great job fixing it up, that's a tall task!
I hope that they ran him off, just sent him down the road kicking rocks I know that I wouldn’t be able to trust him after this screw up Unbelievable simply unbelievable
