As a former crane repair guy, i have several comments. Heating a boom section to straighten a wrinkle makes a soft area in the boom. Where did they get the new plate for the repair? Is it alloy steel like original construction or just a chunk of mild steel? Did they have a sample of the old boom material tested to see what is or contact the factory to find this out? I wouldnt load test or certify this repair and I have done this repair several times. Trigger welding isnt welding. No attempt to check overall straightness with a string line or laser. And finally, if you have to use bondo to make it look good, you shouldnt have even tried to do the job.
Poor guys doing it have no glasses, ear protectors, respirators, or closed toe safety shoes either. I’m guessing safety is a bit of an illusion in that shop.
Мягкий меттал поставили, там должно быть легированная сталь. При нагрузке стрела сломается именно на закладке из сырой стали, это может привести к серьезным последствиям...
Not to discount this video at all...but I think a prequel of this crane when it broke would be at least as horrifying in terms of safety as this. Actual build quality may be a toss up in terms of end user experience. What's another time bomb gonna do in a room full of time bombs.
I was a bit concerned about the bubblegum weld, once I saw the body fill going over it all is good as that will strengthen it up. I assume it's guaranteed until the first lift or 'till it breaks whichever comes first? (If it lasts long enough to get it reassembled). Nice paint job tho.
Как они работают без очков? Я работаю всегда в очках и все равно залетает под очки. У меня в больнице мед карточка вся исписана; Инародное тело в глазу, инородное телов глазу...
None of what they did to make that repair would be legal in the US. You would have to replace that entire section of boom with either new or used. I like the rubber glove the "welder" is wearing on his left hand.
How do we know it's straight ? "we use string". How do we know it's not twisted ? "we used same string". How do we know it's strong to original spec ? "we used car body filler" Will this kill someone if it fails ?? "we can make coffin from off-cuts" omg.
OMG. No safety equipment or guards used, exposed wires coming out of the grinder and also note the inline switch because the factory switch must be faulty. Yep NEVER EVER going that Crain.
u dont repair a crane part u do a new , the steel can be broken beyond eye sight..... but i guess look how many 1000+ crane and lifting accindents in some parts in asia, pakistan,india
