I am retired now but I worked for Boeing for 14 years then Parker Hannifin (Parker Aerospace) for 22 years till retirement. I recognize a lot of those components from my Boeing and Parker days. I worked assembly and machinist duties during those years. I have built parts for most anything with wings both helicopter and fixed wing.
Amazing engineering of the 777 nose gear-especially given it not only steers, it’s pushed and pulled by tugs, supports several hundred thousand pounds of load and extends and retracts!
Thanks for this video! I started my love affair with aircraft at a young age, and I had a special interest in landing gear. I took my love for aircraft, and my love for fire fighting (from my father) into the Air Force. As an Air Force firefighter, I got to be around lots of aircraft, but especially B-52s in the Strategic Air Command. One of the most dangerous incidents was a B-52D at Andersen AFB in 1973 was a BUFF with hot brakes that turned into a fire on number 1 truck. My first duty was the safe egress of the crew. Just after their exit through the main hatch (not far from the burning truck) one of our P-2 crash trucks started putting out the fire. We pulled a handline from the P-2 to complete extinguishment. Another exciting day in the life of a military firefighter.
I'm an aero engine/ gas turbine designer and love aircraft.....it was refreshing to get a video with proper technical detail, so much going on in there !? Thank you, much appreciated!

@@Chris11249 the gear itself is most of the time made of high strength low alloy steel, used for strut and bogie, other parts can be made from titanium or Aluminum alloy.
This is very interesting! All the working parts of just this one part of the huge aircraft is amazing. Many thanks for sharing! Greetings from a Kiwi aviation enthusiast.
Hello Dennis , Firstly fantastic video! Please do more like this featuring different aircraft gear. I'm currently working on an A330NEO model and would love detail on the gear. Secondly please go back to your original video intro, it was soooo good. Synonymous with a Dennis Vijverberg vid.
I finished my A&P school but will work on small planes. Here at LAX you have to do grave yard shift for many years before you are allowed to leave to cheaper areas to live working for the airlines.
So much technology, parts our lives depend on. They have to work, period. And that P40 NLG Box looked familiar, I worked on that project so many years ago.
All those nuts and bolts, cables, hoses aren’t they the things to become loose or worn out from vibration. I thought there wouldn’t be so many individual pieces just hydraulics cylinders and tires.
That must be noe strong cable i see to be exposed to all the elements of being outside in the weather and stuff flying around when going down the runway
Hi, no brakes are installed on the nose wheels is because it adds a lot of weight and they are not very efficient at that location. Main landing gear touches down first with all of the weight on them, making it more efficient to have all the brake power there. The nose wheel touches down later and not much weight is on there to make them efficient enough for adding much brake pwr.
Спасибо! Очень информативное видео 👍. Обычному обывателю - даже представить трудно, насколько сложна авиационная техника. Честь и хвала светлым головам, которые всё это: придумали, расчитали, поставили на производство - конечно же обслуживают и эксплуатируют настолько сложную технику 💪🤝!
@@fredfred2363 the ILS tracking yes, there are also antennas behind the radome, but when gear down is selected the ILS receiver switches over to the ILS tracking antennas on the nose gear doors
So apparently it's an anti corrosion coating, i doubt very much if that is factory applied because it looks like a blind man sprayed that on, missed areas, running heavy coated patches and just looks shabby all round..... No way did a team of quality controllers at Boeing look at that and say "That'll do"
@@dennisvijverbergbrakesrele6098 On the contrary, I would say the camera work is perfect. It's one of the best shot technical videos I've seen, a perfect piece of reference / educational material
Over paid cutting corners always crying they don’t make enough money! Let’s go on strike be cause the bathroom sink has low water pressure and no free vending machines plus Christmas bonus was only 7,000$ this year workers!
Those immensely strong forged landing gear components are amazing close up, the whole assembly is beautifully engineered.

I never knew that a Nose landing gear was so complicated with so many different functions, that was an excellent Video, many thanks 👍👍
Thank you very much

Amazing! All this tech is unheated and unpressurised, yet has to work flawlessly through every flight cycle. Truely impressive to see.

Glad you enjoyed it!
I recognized a few of the forgings in that nose gear, manufactured at a plant I worked @ for 42 +years. Pretty cool🎉
That’s awesome
What materials are used? I'm assuming inconel or some sort of nickel alloy, titanium and stainless?

Didn’t realise how complex landing gear was until I saw this, well done 😎
Thanks
I didn't realize how simple it was until I saw this. 😅
OK, now I'm an expert in the triple 7 nose gear, adding to my resume. How hard can it be?
It's all ball bearings these days! Looks like that Sphetzer valve needs some 3 in 1.
But seriously, this is very cool. Thanks for posting.
I never new there were buttons on the landing gear
That was neat. Thanks for sharing
Thanks for watching

What is the differences between “Brake on” and “Parking brake set” lamps indicate?
Hello, you get the amber light when the parking brake is set, the red light come on when hydraulic brake pressure is above 1900 psi.
@@dennisvijverbergbrakesrele6098
Oh!
Many thanks sir…
great video, thanks for making it !
It’s not part of the landing gear itself but I enjoyed it when a tug operator referred to the “unemployment line” on the gear doors.
This is very interesting! All the working parts of just this one part of the huge aircraft is amazing. Many thanks for sharing! Greetings from a Kiwi aviation enthusiast.
You are welcome.
Sehr gute Videos 👏👏👏👏👏

@@Erik-rp1hi Yes that sucks, as we are pretty small we work nights, but we don’t have a graveyard shift you stuck in for years.

Really great video! I fly the 777 and don’t get much exposure to these kinds of things down below!
Thank you for posting, subbed to your channel 👍
Thanks for the support
When did it get a clean last. cleaning is a perfect way of seeing faults.
Cleaning of landing gears are normally done during A-checks.
Very Interesting. Thanks.
What does the Tip Over Alarm Sensor do?
@@dannywilliamson3340 this will shutdown the aircraft cargo loading system so no more cargo can go to the back of the aircraft.
@@dennisvijverbergbrakesrele6098 Good idea!
All those nuts and bolts, cables, hoses aren’t they the things to become loose or worn out from vibration. I thought there wouldn’t be so many individual pieces just hydraulics cylinders and tires.
There’s a lot of engineering that goes into making sure the landing gear can handle the loads, vibrations, and heat.
That must be noe strong cable i see to be exposed to all the elements of being outside in the weather and stuff flying around when going down the runway
1:37 What is the 'tip over sensor'?
Hi, only the freighter has this, it will shutdown the cargo loading system when the nose gear extends to a set point.
Geez, can that nose gear make me an espresso?
It can crush the beans.
Interesting content but the zooming transitions are distracting.
So I guess I won’t be asking the Jiffy Lube guy to check the tire pressure on this baby!! COMPLICATED!!
I thought it was going to fall off. Maybe the next video...
I like those "spin brakes." Never knew that was a thing.
Yes, I thought it was a friction pad that that the wheels rubbed against.
Why planes don't have front brakes too?
Hi, no brakes are installed on the nose wheels is because it adds a lot of weight and they are not very efficient at that location. Main landing gear touches down first with all of the weight on them, making it more efficient to have all the brake power there. The nose wheel touches down later and not much weight is on there to make them efficient enough for adding much brake pwr.

The glide slope ILS antennae are inside the NLG wheel well?! Wierd.

Hopefully there's grease in the wheel bearings, unlike my jeep CJ7 ! 😊
Running smooth 😉
Allah has given brains to his human
Beings to create machines like these -
Without this humans could not even
Make a toilet seat ❤
Looks like those grease fittings dont get much love
Lubrication of the gears is done during the A-check
Ongelooflijk hoeveel techniek er alleen al in zo'n neuswiel constructie zit!
Shocked employees are allowed to do this.
No secrets are revealed in these videos. And as long it doesn’t interfere with the normal work.
Someone needs to clean their wheel well.
What's wrong with it?)
This time nothing wrong with it, just a video pointing out what is what.
It’s massive.
Well done uploader, the ads were interrupted by random clips of an airplane, greedy 👎👎👎👎👎👎
Is anyone else concerned how dirty it is in there? It looks like oil leaks and more! I'd be very nervous to fly on something leaking like that!
Where do you spot the oil leaks?
Hi, the yellow coloring is an anti corrosion coating that is sprayed on. Nothing leaking in the nose gear bay.
Besides, remember what aircraft mechanics say...If it isn't leaking, it's empty😂
So apparently it's an anti corrosion coating, i doubt very much if that is factory applied because it looks like a blind man sprayed that on, missed areas, running heavy coated patches and just looks shabby all round..... No way did a team of quality controllers at Boeing look at that and say "That'll do"
All the rubber dust is what makes it look so grungy.
All the Braggers in the comments section bragging about themselves as usual 🙄🙄🙄🙄
Now I know why these planes cost hundreds of millions dollars. All that engineering just to steer it left or right.
Nice but these kind of videos give the Chinese all they need to know.
@@fostergrip well as there are Chinese companies flying B777’s they just need to take it apart and put it in the copier 😉
The video is terrible - the zooming is annoying
