[@CharlieBehrens]

Hi Grady, I'd love to see a series of construction techniques that have moved to fully electric machines instead of gas or diesel. Bobby Llewellyn on the FullyCharged channel has covered some of the smaller ones, but what about that big gear that has moved over to cleaner power?

[@emrahdincer]

How about on the various compaction machines/processes such as dynamic compaction or vibro-compaction. I've worked around both and they are fascinating but I don't know the science of what makes them work.

[@RobertCraft-re5sf]

[@tgruetzm]

My wife and I have always enjoyed your videos. Our son (18 months) is obsessed with construction equipment. We don't really let him watch TV unless he is sick but we discovered this video today and have NEVER seen him so happy and engaged beyond seeing the vehicles in real life. Thank you for inspiring the next generation of engineers!

[@leenevin8451]

Is that a good thing not being allowed to watch TV?

[@whirlwind872]

​@@leenevin8451depends what you watch. When you stop watching TV you realize how terrible it is on the rare occasion you see it. The main drawback of not watching TV is the social aspect, since youll be out of the loop on some things. But as far as content goes, theres much better content online than on TV

[@rogink]

Lego mostly seems to be film characters there days, but if you can get hold of the simple blocks, no doubt that would inspire your lad to create his own construction projects. I'm impressed that he can follow this fast moving content. For something slower - and more age appropriate - I'd suggest 'Bob the Builder'!

[@d_kortman]

@@leenevin8451it’s best to limit a child’s interaction with devices nowadays. Basically everything on the internet has found a way to hijack your brain’s attention and reward mechanisms in ways that will keep you engaged and consuming as much as possible. This can lead to an addiction and/or reliance on technology at an early age for kids, as well as poorly influence the development of their brain prioritizing things like instant gratification and emotional dissociation. Many parents nowadays will give a child an iPad to watch kids shows when they’re upset just to ‘shut them up’ which is a big culprit of the aforementioned effects. This will lead to the child relying on that instant gratification to ‘deal’ with their emotions by basically just blocking them out by being distracted by carefully curated shows to keep a child’s attention span on track, making sure that kid consumes as much time on their videos/shows as possible. So yes, it’s a good idea to limit a child’s interaction with TV’s, internet, video games, and other electronics to avoid these adverse effects until they start maturing and slowly let them have more and more access. If you want the best results for your kids, stick with hands-on activities and tasks that keep them entertained and reinforce those good habits. It will go a long way.

[@mightymak1416]

It’s fantastic that he enjoys the video, but I think only letting him watch TV when he is sick might lead he to connect sickness and TV/treats, he might learned to act sick to watch TV, which won’t be great

[@athompso99]

I wish this had been an hour-long video that went into more depth on each machine. Two other industries with lots of bizarre equipment that I'd like to see explained are Railroads, and Forestry.

I spent a summer in college working on a large construction site, and during one of my first days on the job I received a piece of advice from one of the equipment operators that has stayed with me for going on three decades now. Lucien was an ancient French Canadian who drove the bigger of the two excavators on the site, and I'm pretty sure could have performed heart surgery with it if he'd had to. One morning before climbing into his office for the day, he noticed a bunch of us young guys standing around admiring his rig, gestured to the business end, and told us in his impenetrable Acadian accent, "You guys stayway funat bocket. Thas donzhrus." Best safety briefing we got all summer.

[@graysonmclester9137]

Love the video! Sad one of my favorites didn't get a mention: the snooper truck. A cousin to the boom truck that. Instead of lifting the bucket to a high point, it is designed to allow the bucket to go underneath the truck. They are typically used when inspecting a bridge, the truck parks ontop of the bridge and the boom is used to move the bucket so that the occupants can inspect the underside of the bridge for damage or other signs of wear that may need to be fixed.

[@justindunlap1235]

I was wondering what those were called, I recently watched one in action inspecting bridges. The operator was doing an impressive job coordinating with the driver to maneuver the boom through the steel trusses.

[@Merennulli]

I don't know how often they are used, but I see them about 3 times a decade inspecting some part of the twin bridge I use every day. It's 2 near identical 3 lane bridges and they just close off a lane and creep along it, putting the bucket between girders.

[@bp-ob8ic]

[@bruhice6058]

[@bp-ob8ic]

@@bruhice6058These drones can carry a variety of sensors, including x-ray and infra-red. While hands-on is great, the ease of access allows the inspections to be more more frequent, and provides more specific detail than the average eyeball. AI is already involved to help avoid the structure where GPS is not available. I suspect that AI is also used to enhance the defects detected.

[@jordanamoth6724]

One thing you missed is a hydrovac. It uses water to remove soil around existing pipes so it's safer to dig around live wires

[@seanrogerson4120]

Or colloquially, a sucker truck! Good pick.

[@shademournthepegasi2366]

I just call them pumpvac trucks

[@mafarnz]

The machine that you call a pipe layer is very common in the railroad industry, where they are called “side booms”. They are commonly used in derailment cleanup jobs. Two or more side boom dozers are really useful for picking up and moving rail cars back to good track or moving out of the way for track rebuilding. Large heavy locomotives can take 6 or even 8 side booms to pick up and move, which requires careful coordination by each operator.

[@SkyhawkSteve]

I spent 20 years as an engineer at one of the "big yellow machine" companies, and it's a challenge to keep up with all of the stuff being produced! A bit more detail on each subgroup of machines might be fun. Even I learned a bit in this video!

[@swolebro]

[@rogink]

Seeing that shot of different plant made me think - why are they all yellow? I suppose it's obvious with hindsight - the colour stands out, especially on a construction site. But someone must have thought - this is a good idea. Of course it's only moving plant. Tower cranes always seem to be red - probably cheaper paint.

[@mr.d.rektorstudios]

Every time Grady talks about how much he loves watching construction, it reminds me of my idea that I think state departments of transportation should set up live feed cameras of the worksites, and put them on their websites and youtube channels, and when a job is done, take that video footage, speed it up to a more reasonable watchtime, and then upload those as well. Not only would people enjoy watching it, it would raise awareness about just how much the process involves, be useful for education, get more people interested in going into those fields, and it would (hopefully) encourage onsite safety.

[@JeffMTX]

Very smart! It would make drivers more accommodating of this traffic jams too

[@PianoKwanMan]

Some do! You can watch a bridge being demolished and rebuilt in a few days. They make amazing promotional materials. So, the company releases them, or put them on a public webcam.

[@rogink]

As a junior engineer one job I was on was an underground reservoir. I set out the excavation area and was expected to check on progress. But I remember being mesmerised watching the skill of the excavator operator digging and trimming each slope. I probably should have been planning for the next stage of the project!

I was watching the demolition of an old factory near me and was impressed at the skill at which the various machines were used. One front loader was taking down a wall and had to stop to check on something. The operator used the boom to support the now weakened wall while he did his check. They had skid steers there as well and what impressed me was that one was lifted to the roof by a crane and was used to remove stuff from the roof.

[@jordanashe2586]

Similar to the bucket truck is the line truck. About the same size as a bucket truck, but with a crane arm and auger to drill and set utility poles.

Milled pavement is often a bit of a concern for motorcycle riders. If, as happens with wear, the cutters are uneven it creates longitudinal grooves and the bike's wheels tend to follow those. Growing up in northeastern Pennsylvania a sign of larger building construction (bigger than houses) was borehole drilling to determine if coal mines are under the site. There are maps from the coal companies but they are known to be inaccurate.

Pretty sure this could easily be turned into a series to cover a lot of other industries: forestry, mining, railway construction, and canal/bay/waterway dredging and maintenance. Of course it's also interesting to see how many machines from agriculture get adapted to use in other areas as well - especially given the large variety of equipment used in all the various forms of agriculture. In fact it's been years since I've seen a dedicated scraper/earthmover, as most large construction sites I've seen in the south eastern US are more likely to use a tow-behind version pulled by a large articulated farm/ag tractor --- with the tractor occasionally pulling multiple in a chain. Will also frequently see large/heavy disk harrows/plows on construction sites to loosen/breakup/dry(?) the soil/clay for other equipment to work. It's fun to see & learn about the equipment that literally changes & builds civilization - especially since the types of machines and equipment continue to grow and expand into new areas. In the last year I've seen my first stone slinger truck driving down the road (something I never knew even existed until watching an Essential Craftsman video about them).

I am not in the construction industry, but from when i was very little, I always was so fascinated by these machines but didn't understand their purpose. Thank you, Grady, for showing us. Also, please do more lists on trians, mines, and various other industries.

[@BarBar3ar]

A version of this for mining would be pretty cool. I know about the big things like bucket wheel excavators but I bet there's all kinds of weird specialized equipment for the constraints of underground work and for mining various materials

i work in construction and engineering in the DC area. i really love watching the construction equipments do their stuff. Exquisitely engineered, expertly operated, tough and strong like titans. Such a confident and purposefully existence

This needs to be a monthly series where you feature interesting machines and explain their purpose. Please like this comment if you want this to happen!

[@UltraGiantMeteor2024]

Again, Grady…words can not truly express how much I enjoy your videos. Not only the content, but the way it’s presented. The visuals are wonderful. Your commentary is both informative, and concisely expressed. You truly are a gift that keeps on giving. Keep up the excellent work! I will impatiently await the next video 😁

[@UltraGiantMeteor2024]

@@David-bv6xz absolutely nobody on an engineering KZbin channel is asking for unsolicited, unrelated, and unnecessary religious propaganda. Peace be with you, but maybe take this conversation to a page not dealing with science. Most scientific people aren’t going to be convinced to subscribe to a very antiquated book of stories.

[@truevision1463]

In India, we call every excavator a JCB, regardless of the actually company that makes one. A skid steer is called a Hitachi.

[@V8therapy2186]

Hitachi doesnt make skid steers

6 year old me would have loved a video like this being shown in school. 24 year old me loves watching it at home.

[@AnanasWolf]

In the Netherlands we got another specialised machine for paving, called the street printer. It's used for brick roads. It might be a funny machine to give a look at

[@stepheneyles2198]

Is that the one they feed blocks into by hand? Saw a video of it somewhere, no doubt a quick search would bring it up! ;-)

[@Appa-the-husky]

Yes, it is still hand-work but standing. Way better and faster.

I work on railroad for 33 years and you could make a episode of its own just to name the various machines we use there. From the single hi-rail pick-up to the huge undercutter, there's a world of its own.

[@barriewright2857]

Brilliant this is something that should be used as education and or information for the construction industry.

i remember back when i was a kid having VHS tapes of construction demos and all around heavy equipment operation. its so nice to have a modern medium for it now

[@dazac21]

Having worked around most all thoses machines I think you did a great job. Doing a list of semi trucks and trailers would be cool. Most people don't realize how many different types there are

[@LucarioBoricua]

Or just how specific they can get in their functions. Most people know of general stuff like flat beds, dump trucks, single unit box trucks and tractor-semitrailers with intermodal or tanker containers, but there's definitely a huge world beyond these.

[@TheDayzman]

The only thing I am missing (probably only because I have worked on one) is the drilling rig. Mostly used for wells but also for construction if you need to dig below the ground water. Than you install a couple of temporary wells with big pumps to actively lower the groundwater level.

[@robmurphy806]

You forgot to mention geotech drills for subsurface investigation or diamond drills for mineral exploration. Third generation driller and I've worked with diamond and geotech drills mostly but have worked with cable tool and rotary well rigs.

[@seanrogerson4120]

I like your comment about the myriad different names people use. I've been a special inspector for 11 years and I always tell new people that the toughest part of construction is learning all the names. Woe be on the inspector who uses the wrong name for a piece of machinery to the operator!

[@smidge-J]

one of my favourite machines is the water cutter. It shoots high pressure water directly onto the road surface to cut it up a bit, rough up the road surface a bit so there is more grip on the road, and less chance for frost and ice to form. A lot easier than having to repave entire sections of roads, especially in rural areas.

[@wyndwalkerranger7421]

Thank you for your videos, as a retired civil engineer I really enjoy them. Would like to see a video on electronic grade control or grade control in general.

[@basshead2003]

Copperhead Marie uses grade control on a number of his dozers and graders. He’s done videos about the system he uses, but I can’t remember how much detail he goes into.

Elevated scrapers are the coolest; but love the utility of the small skid steers!

Thank you for this. If you aren't aware there are a few drone pilots that have been offering almost daily coverage of the construction of Tesla's new factory site in Austin, Tx and Berlin, Germany from Summer 2020 to now. It has been fascinating to watch the different parts of the process come together, with excellent phasing to get the work done.

[@lindastarr3751]

Thank you. As a parent of a three year old, I needed this information.

[@Badge124]

Many years ago I would read the same book to my 1 year old son every night. It was a book about construction and logging machines and he was fascinated. This brought back memories. Thank you.

[@Sandy.J.Lloyd.Sr.]

I would like to see an episode of machines used in the space industry, even small handheld tools would be interesting.

[@gratedcampbell9553]

The explanation of all explanations

[@brandongaines1731]

I've seen those tires-in-a-row compactors in use at I-70 pavement replacement work sites through Kansas, and though I could tell that they were some kind of roller, I couldn't figure out what they were used for. Also, those pipelayers are often used by recovery companies to get big locomotives back onto the track after a derailment, often working with 4 such vehicles: 2 with the crane on the right, 2 with the crane on the left, positioned around the locomotive in such a way as to ensure proper rerailing of all of the locomotive's wheels with all 4 pipelayers facing the same direction. It's often the most efficient way of doing the job, proving that a machine doesn't necessarily have to have interchangeable implements in order to be useful in multiple different scenarios!

[@Michaelonyoutub]

I had a physics teacher in high school who spent his free time looking at site selling old construction machines, which he would buy for a few hundred bucks, and use in an empty lot he owned as his own adult sandbox. He was a kid who never really grew up and was my favourite teacher ever.

[@Fdco]

love your content and here's a possible future video Idea: A train recently derailed in the Gotthard base Tunnel. It destroyed parts of the track and is currently being rebuild. It might be interesting to look at how such a Tunnel is repaired in record time. Keep up the great work!

[@sirBrouwer]

The only add on to all these would be a basic tractor. Atleas where I live they are often both used as a addition to dumptrucks and for bulldozer/wheel loader like work. Do to there use on farmland they are very good at driving on mud at places where a dump truck might get stuck.

[@theprogrammer32]

I was LITERALLY on a recent binge / hyperfixation abt all these road vehicles and KEPT looking them all up. I was literally thinking about making articulated loaders and extending boom lifts in space engineers day in and day out. Recently we've had a lot of work on the main highway and I've seen all types and sizes of machines. I've literally been DREAMING of the chance to hop into one of those huge loaders they use at quarry sites and just lifting up buildings' worths of material. But I don't want to do actual work though...

You know, it's a little off topic for you but there are military models of trenching machines intended to, well, make trenches. As in, for infentry to take cover in. They're pretty cool in spite of the nature of their niche. Sames can be said of other military engineering vehicals.

[@seanbrockest3888]

I work in an underground mine. We have a lot of this equipment, but it's all been modified to be no more than 6 ft tall, some of it even shorter. It's really hilarious seeing a 5-yard scoop that's only 72 inches tall, but we don't have any other option.

[@phillipmoore6295]

I'm a retired Operating Engineer, IUOE Local 15, 38 yrs. I have run or worked with all of the machines that you depicted. I would however, add two machines. 1. Pipe pulling machines. Such as Ditch Witch or Vemeer LM 20, 40. (Used for irrigation and small water mains.) and 2. Brocks, remote controlled swiss army knives. Which are use in places too dangerous for a manned machine to work.
