Every Construction Machine Explained in 15 Minutes

🏗Hope you don't mind me trying something a little different. What machine would you add to this list? 👷Watch all my videos early and with no ads: go.nebula.tv/practicalengineering

I think we are pre programmed from birth to get excited when we see excavators and bulldozers and other construction equipment i swear.

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.

The best parts about being an engineer for a company that makes heavy, off-road, industrial machines is 1) seeing them working out in the real world and 2) having scale models of those machines on your desk to drive around.

This started to feel like a children's book in the best possible way with how you kept up the pace and succinctly explained each machine

CAT dealership mechanic here. Loved it. Would also love to see one on the forestry side of things. Skidders, feller-bunchers, knuckle boom loaders, etc.

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!

I really had no appreciation for civil engineering until I discovered this channel. Thanks you!

Since you asked: I'd like to see various vehicles in the logistics industry explained. I've seen so many different kinds of forklifts in my life and I find it fascinating to figure out why they're shaped the way they are! You covered one of them here and it was interesting.

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

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.

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!

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.

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

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.

I would love to see a breakdown like this for the airport / airline industry!

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!

As someone who works for a Caterpillar dealer I loved this video. I would be really interested to see you cover the automatic grade control construction machines are using now. Great video!
