What is required really isn't sufficient to keep vehicles from sliding under the trailer, especially when offset. https://www.youtube.com/watch?v=bT3G-kcKN70 Edit: shouldn't have just a video as a reply. Frankenstein fucked around with this message at 02:21 on Mar 8, 2013 |

The anti-submerge bars on the trailers in the US look pretty crap. The ones in Australia have angled re-enforcements so they just don't collapse under like in that video.

The lovely US one would at least be marginally better if the material thickness was enough to prevent tearing. Would still bend with that crummy gusseting but from the underneath camera you can see the whole bar is just tearing off the mounts. I'm not sure what the US legislation looks like, but the language probably needs to be changed to enforce more stringent design and material standards. The  one does a really good job, it just needs the main support beams at the edges of the trailer. Possibly a triple beam setup to maintain center strength.

I basically figure if someone rear-ends a truck, they probably were being a dipshit in some way. It's not like they're small, hard to see vehicles that make sudden moves and can't be spotted a mile away.

Well its like they tell you it takes a football field to get to a dead stop from 60, which is false if you actually know how to downshift and brake properly. But they say things like that because most people cannot stop from that speed, and that is probably what happened. They thought they could stop or move in time, something blocked them in or they underestimated the speed change, and wham right into the truck.

Had one simply decide it was coming into my lane, no signal, and I had to slow down to dot get sideswiped by the trailer. The only thing that saved my rear end is that there was no one behind me, considering I had to go from 10 over to 10 under in the fast lane with literally ZERO warning.

I had this happen once on a really ugly road and ended up having to make a third lane out of two. Turbo kicked in and I got the gently caress around, and didn't really get the adrenaline fail until after I got home nearly an hour later. Most truckers are fairly sane (excepting Walmart branded tractors).

Except you bothered to mention "no signal", that's standard here  I haven't had problems with truckers because, having driven a large, heavy, slow vehicle with poor rear visibility, I am constantly aware of the fact that they can't see well behind and around themselves, sometimes get fenced in or cut off by some idiot, etc. I try to stay either a safe distance behind (even when in another lane) or ahead of them, and pass/get out of their blind spots as quickly as possible. Hell, I even let them into my lane once in a while if it looks like they're about to get screwed by a merge and no one else is letting them in. Thread content: An LBZ block Duramax that a friend just lost.   I apologize for the terrible photo editing, I didn't realize he'd left a bunch of blank white space around the photo when I uploaded it. Pretty sure he had a straight pipe, tuner, etc on it (aka probably had this coming, if he wasn't being careful)... and had just lost some injectors to bad fuel. Best guess is it hydrolocked on fuel, rings stuck, piston melted, or piston seized in that bore, the injectors he got for it mostly fixed the issue but it threw a rod pulling out of a side street a few days later.

And another one, shamelessly stolen from another friend who is "the car guy" in his circle of friends...

The 'High Ride' air solenoid is stuck open on my bus, the road mechanic couldn't change it out today so it's going to the shop tomorrow. Driving empty feels like I'm driving a bouncy castle, and driving loaded pisses off my passengers. I've apologized for the rough ride hundred times, but at least the roads here in central Florida are nice and flat. Note: The back end of the bus is up about a foot and a half from where it should be, the air bags are completely maxed out and I can't believe they haven't blown. Water from the toilet has splashed the ceiling. It drove down from Ohio like this.

The company does the maintenance, but the company garage is currently 1,038 miles away. Stuff like this rarely happens, but when it does I call dispatch and start the following process: -Is it really that bad? -Shut it down for 5 minutes and call back. -Can you do anything to fix it? Try This, Try That! -Can you make it to where you're going? -Can you at least make it to _______ rest stop? -Alright we'll send out a road crew -Alright take it to ______ shop if you can. -Alright  I guess we'll send another bus out, sit tight for the next 1-5 hours and by the way you'll do nothing but low-paying casino runs from here on out.

I wonder if part of the problem is that as cars have become more crash resistant in the front, the bars haven't kept pace? So while they'd hold the line against the front end of a 30 year old car, a new car bends them right back.

Cars have become safer by crumpling more easily. That should make that hang-down bar's job easier, not harder.

Occam's Razor. Bars become mandated, no mandate on actual strength, just placement, businesses cut costs by making them cheap-as-gently caress. Simple. No explanation beyond that.

So that you have a flat floor in the trailer. Plus it's cheaper to make a simple box on wheels.

So something roughly in this shape that holds up more like a wall instead of crumpling away is too hard to do?  I honestly know nothing about 18 wheelers.

Would it, though, with those new deflectors I'm seeing on trucks? The ones that look like an "A" from the top down, with the point in the middle of the front axle and the tails as wide as the rear of the box? The ones I see look like this, but with the front of it closer together or joined into a point.

And don't forget the tandem slides.

So some guys complain that this portable 75hp exhaust blower is "making a noise." An hour or so later, they call back and say it stopped working and the breaker popped. So we wander on down, and take a peek in the exhaust.  That's not good. Disconnect, replace (no easy task, as this unit is close to 1200lb, 12' tall, 14' long, and 6' wide. Back at the shop, we get the intake plenum off.  Maybe the impeller should be attached to the output shaft flange somehow. Just a guess. Get the intake off all the way and the impeller out. Two and a half of the six bolts are laying in the bottom.  So The Story: These blowers were manufactured five or so years ago. They were intended to be spares, so they went into the yard. They got pressed into service a few months back. Now at that time, someone noticed that they'd never been touched since they were initially delivered. "I'll do some PM," he says. There's a grease fitting in the rear, but not the front. The manufacturer's recommended break-in instructions said "ensure proper lubrication" but the company's maintenance deck didn't have "grease the bearings" as an explicit step, so no grease. The blower started to make "there's a dry bearing" noise a couple of months ago, so one of our guys went down to grease it. There's a grease overflow cap on the bottom side of the motor at each bearing. It's completely impossible to get to the front drain cap due to the design of the blower housing. Anyway, grease goes in the back, and water comes out of the drain. That's not good. Forty pumps later, and cleanish grease starts coming out. He then swaps the grease fitting from the rear bearing to the front. Pumps 20 pumps in, and no more will pump in. After we get someone to rig the motor out on Monday (75 hp is too big for me to lift), we're gonna take a look at that front bearing, which has probably never, ever, ever tasted clean grease since its construction five or so years ago. It'd probably be cheaper and quicker to just take the thing to the scrapyard and use the money to buy a new one. I didn't take pictures of all the rusted bolts or studs we broke. For some reason, clamping aluminum plates to steel flanges with stainless nuts doesn't work as well as some would have thought. Especially when you leave it in a rainy waterfront equipment yard for four years without ever glancing at it.

Doing u-joints with a press or a vise is the easy way to hate yourself and buy more new parts than you needed to. 5 minutes with a flat screwdriver, a BFH, and a vise. I can quite have a jeep drive to me and replace a ujoint in under 30 minutes including taking the wheel off and pulling the axleshaft, even if the unit bearing hasn't been out of the knuckle in years. https://www.youtube.com/watch?v=9PpR-DcRV08 Versus screwing around with a press, wondering if it's going to pop loose, wondering if the ears are going to break/bend, etc. I'll use the vise+BFH method every time.
