Loading dock repair

Welding and fabrication done to repair an issue with failing concrete on the loading docks of a large foodservice company

[@joaoveloso4954]

That was genius and the best part is you backing everything you said 100% with that before and after, nicely done.

[@NBSWELDING]

I appreciate that!

[@Lull622]

That hammer & hot tack tip you shared is great. Amazing work as always.

[@randomschittz9461]

Your rivet remover is badass! I think it’s about time for some thumbs up t shirts.

[@NBSWELDING]

Mom is lookin into it...👍

[@chucktaylor4958]

The hammer blow increases the pressure which increases the heat of the weld, and, therefore, improves the weld, as well as closing the gap. Your construction is well thought out, executed, and comprehensive. Great looking job.

[@stalinfontana]

A lot of job for just one person. Well done!!!

[@NBSWELDING]

The boss from the big construction company that built that million dollar addition said that they just didn't have the manpower to fix those docks... So I fixed them by myself...in 11 days

I appreciate that hot tack method. I know that'll come in handy. Keep making these videos brother, I'm hooked.

Hilti screw ancors have been my go to for concrete lagging you can use apoxy with them but ive found that its not necessary ✌🏻

Just found your channel the other day and watched the bridge build. You have yourself a new sub.

Ive been doin hot tacks ever since i started stick welding stuff (old man at my job taught me them) but ive never seen a slow-mo video on them. Awesome shit!

[@lowrider9249]

Nice work, keep the videos coming you have a lot of good info and tricks on welding and fab work I enjoy watching all your stuff.

[@NBSWELDING]

Thanks

[@deepwinter77]

That hot tack is a great idea, thanks 👍🏻 It looks like there's not enough rebar in the concrete and the anchor bolts for the plates are to shallow. We built some dock levelers about 20 years ago in a Cadbury chocolate factory in Dublin Ireland. There was a lot of rebar designed in to them. They actually designed thick steel angle iron set into the concrete with large threaded bar bolted to the pieces of angle steel coming out through formwork cast deep into the concrete. We just did the formwork and rebar so we were gone by the time the bumpers were bolted on but seemed like and extremely robust design.

[@NBSWELDING]

I agree...there was not enough rebar and the way the dock bumpers were originally designed was just not strong enough...it is obvious that there is a weak place in the concrete where the wall and floor were done in two separate sections there at the corner also. I just wasn't built strong enough for what its for

[@deepwinter77]

@@NBSWELDING yea makes sense, the design of the ones we did was monolithic, slab & wall poured together with the sides and rear forms suspended.

Thank you

[@mikef6879]

I wish more of our customers would come off the money for repairs like this. I install this stuff daily and youd be surprised some of the walls they want the equipment mounted to. Cmu's, hollow core precast (foam in the core) etc. Wall thickness less than an 1" in alot of cases.

[@johndenton5555]

that 'bottom bumper' isn't a bumper. That is the under-run guard that is meant to prevent an auto or truck passenger cabin from running up under the trailer if hit from behind. An aid to try and prevent decapitation fatalities in these accidents. might not want that to get bent up before it's needed.

[@NBSWELDING]

Good info...thanks for watching and commenting

[@redzed40]

Great work mate

[@NBSWELDING]

Thank you

[@Jammer.1]

I think the heat from the weld helps the epoxy set faster As for the dock plates thats a great idea i seen some i would not drive a fork lift over because there falling apart ! Love your work !

Thank you

I work for Euclid chemical. Cool to see one of our product being used!

[@cgindustrial1859]

Those flip-up docks have a much less structurally sound pit design then a standard dock leveller. Good money maker for us dock techs....or welders.

Years ago I melted sulfur and poured it in the holes to anchor bolts with

[@cgindustrial1859]

I;m a loading dock tech. this repair is actually pretty common. Minus the bottom bumper, which is completely useless...just an upsell.

[@Farmersamm]

I guess I ought to start off with a little house cleaning. I feel absolutely terrible about the thing I said about the bridge. It's not my mission in life to make people feel bad. Anyways................this turned out nice. You're absolutely right about those vertical corner plates. The main bumpers are nothing but a cantilever. They want to tilt when the truck hits 'em. The vertical plate will take the load, along with the plate you put over the flat floor in the pit. Nice. As far as that lower bumper,, by the DOT bumper hook.............................. Those guys are crazy. All that bumper need do, is protect the safety hook mechanism. No way it's gonna be able to match every DOT bumper out there. You can look at 20 different trucks/trailers, and the DOT bumper is gonna be in a different place as far as height, or distance from the actual rear of the truck. They're all either designed different, or have been tweaked by getting hit, or damaged when guys pull away from a dock without making sure the safety hook is retracted. I drove for years, and I never saw any two DOT bumpers in the same place.

[@NBSWELDING]

I don't think ya made anybody feel bad...certainly not me...I just think your claim that the pier pins would shear off is unlikely...each pier has eight 3/4" stainless steel pins and four 1" cold rolled pins As far a spalling, underneath the channel bases that the piers set on we cast a new section of cement using Rapid Set Cement All (9,000psi) to spread the load out across the old concrete footers so I think it could suffer severe spalling for a century and never remove enough strength to cause a structural problem with the bridge Thanks for watching and commenting 🙂

[@dont-want-no-wrench]

whichever co that is is keeping an eye on details to get that repaired right- lot of cos would just let it go

[@jamesward5721]

It ain't - it's the rocking up & down as the forklifts enter & exit that does the damage to the bay. I worked out a spring loaded dock bumper that cut that issue down to nothing - being too poor to get patents & whatnot, I got sidelined on those - but they work. The dock bumper has to go with the lorry. Resistance is futile.

[@HamJamming]

I've been watching your videos and find them very interesting. I was just wondering a couple of things. Do you ever do MIG welding with gas and .022 wire on auto body sheet metal? I am trying to learn how to do that better. Also, do you ever have occasion to do any brazing (brass, not silver)? I enjoy doing it because you can build up such a nice fillet.

[@NBSWELDING]

I don't do much of either really...I rarely weld body metal or braze

[@johnmcgowan9903]

I'm trying to figure out how you didn't hit any rebar drilling those holes, every time I drill those I hit Fukn rebar!! LOL

[@NBSWELDING]

Yea...starting to think they took the rebar home and made a deer gambrel for everybody in the county...I drilled a total of 70 holes 8" deep and 1-1/8" in diameter and didn't hit shit

[@andrewrobinson2869]

What about rusting on the front . Are they going to prime & paint ?

[@NBSWELDING]

They said they would

[@NBSWELDING]

They have maintenance people that do stuff like that

[@davidkenworthy7548]

Looks like your gettin the hang of it,.... what's the hash marks inside your door?

[@NBSWELDING]

I used those marks to keep track of the number of wellheads I welded on the gas wells for Antero Resources when I was serving their drilling operations here in the Appalachian Basin

[@tangowhiskeytrailertranspo6662]

The damn steering wheel holders that are slamming into the docks need to be fired. If they slam into the dock hard enough to do that kind damage, just imagine how hard they slam into the kingpin whenever they hook-up to a trailer.

[@NBSWELDING]

It has something to do with the way they dress...when I started welding in 1990 truck drivers wore jeans & cowboy boots and they could squeeze a pinpong ball against a loading dock while talking on their CB radio and lighting a Marlboro and never bang the dock. These drivers I saw while I was repairing these docks wore shorts & flip flops...they all had Bluetooth head sets on...3 of them had lollipops in their mouth (no I ain't kiddin ya)...and they backed up until they hit the dock like a 40 ton wrecking ball

[@tangowhiskeytrailertranspo6662]

@@NBSWELDING Sneakers were outlawed on the property of most warehouses when I started driving in '93. As time goes by all common sense rules seem to go by the way side, sad thing about it is fools get hurt and the property owners or trucking companies are stuck footing the bill- in one way or the other. I had a great teacher, my grandfather owned his own truck when I was born. He hauled milk and I went with him everyday till I started Kindergarten, then on weekends till I was in the 3rd grade later in life he began hauling meat for Monfort. I learned finesse from him. Anyway sorry for rambling. Thanks for the video and especially thanks for the reply. Love your work and your videos.

[@TheGamingKing64]

It is because of the automatic transmission in trucks now. You can't just easily roll into the dock bumpers. There is no clutch to hold in and roll. You have to have your foot on the petal or off. When your off, it stops rolling.

[@Doitgood52]

Seems stupid to me to have a truck reverse into a SOLID steel and concrete wall! Of course the concrete is going to fracture.. there needs to be a method of softening the impact.. say some sort of shock absorption.. like a leaf spring, just sayin 😊

[@NBSWELDING]

All I've ever seen on them is the bumpers...rubber bumpers on the loading dock and rubber bumpers on the trailers...when they make contact the rubber on the truck hits the rubber on the loading dock The issue I saw when I was working there was drivers that hit it far too hard...they need to make contact to dock in correctly but some of those guys bash into the dock hard and rollin fast...if I owned the place I'd do something about that problem...it's just blatantly unprofessional if a driver cannot dock in with some degree of control...those loaded trucks are 40 ton wrecking balls in the hands of an unprofessional driver

[@armandhammer9617]

Don't waste your money on liquid nails or gorilla anything, those products are inferior to almost anything else imo. (carpenter 35 yrs)

[@NBSWELDING]

If not liquid nails or gorilla glue then what products do you recommend for use with steel, concrete, and block?...I know I wouldn't use the Euclid epoxy every time because it is far to expensive for some applications...on steel base plates on concrete I've drove steel pins in with no glue at all before and that works fine to prevent the base plate from moving but any adhesive would be better than none...even it you just shot some silicone in the hole it would be something sticky that could offer some corrosion protection
