Love the attention to detail on the exhaust cover, beveling the edges to close up the gap to the mesh.
I love your music you are playing
This is pure craftsmanship.
Time and knowledge = perfection.
You have my vote I'm now a subscriber from Down Under 🇦🇺
Wow, brilliant craftsmanship. I think i got myself a new series to follow. Keep it up!
Brilliant job, the project is really coming along nicely, cheers
Super quality as usual!
You need to clean the aluminum with an abrasive to remove the aluminum oxide before welding. Also wipe the weld area with acetone to remove anything else that would cause a problem. As a 60 year tig welder take my advice and get nicer welds. Aluminum oxide forms on the surface over time, it melts at over 3000 deg f the aluminum melts at 1100 or so depending on the alloy. Removing the oxide before welding will make a big difference . Thanks Great job on the project
hi, yes it is not easy to weld alu. at least it is going in the right direction. I use a stainless steel brush and acetone, but still find it difficult to get a clean weld. have a very cheap welding machine too, can blame it 😉
Awesome build. We posted this video (and the others in the series) on our homemade tools forum this week :)
Super impressive, very sophisticated and very very well built.
I'm so happy I found this channel! Awesome videos!
dude, this is just awesome
Excellent!
👍👍👍
You should connect expansion tank closest possible to centrifugal pump suction to keep pressure in suction as high as possible. Now when the pressure limiting cap is on the top hose is kind of of nominal pressure setting of system... Of course top hose needs to deaired but maybe a smaller hose (orifice kind of like) would do the job and main inlet from expansion tank with larger hose to pump inlet.
You have a lot of patience! :) Very nice job! Keek up the good work, we want more videos 😁😁😁
Thank you Edgar 👍🙂
Super!
beautiful job
Роскошь 👍👍👍
Jävlarr va bra detta kommer bli!
Excellent , just found a new channel worthy of many replays, well done. I just know I missed it or you did not show the hinging access or another mechanism to the engine, the detail I see makes it impossible you omitted maintenance access... Again you have a new subcriber for a long time going forward, love it when people have the opportunity and ability to make things and machines, ex aircraft mechanic myself.
Hello,
Yes it was maybe a little unclear. The two hoods are fitted with a total of 6 rubber straps and are very easy to remove for maintenance. No hinges.
Thanks for your comment.
Really great video. I’ve learned a lot from watching you. I noticed you are using a Eaton Hydraulic Pump. What size pump would you suggest for a mini excavator (like the previous project you had)?
Hello and thanks.
I really want to help you but I actually dont know. I´m not so "in to" hydruaulic. I have used parts from similare size of machines (scrapped). So it is trial and error in my case.
Great construction and skills. Is this a pure hobby, just for fun, and/or you more make things because you find mass produced equipment not suiatbale enough for your purpose?
It's just a hobby to build stuff that I need 🙂
Good job! Where in Sweden are you located? Cheers from Copenhagen.
Thanks Denmark 🙂
Close to Stockholm
what do you think, how much weight can those engines handle? (So max lift capacity, not counting for the other machine limitations).
it depends on many factors. which pump, size and number of lifting cylinders, where the cylinders are attached to the lifting unit (gear ratio) and how fast you want to be able to lift.
theoretically, my machine should be able to lift 1000 kg but I would guess that half is more realistic.
@@AlfaSeven and what do you think can the axles handle?
@@kaistumer198
The wheel motors is Ross me170 from Ransomes Greensplex 160.
Don´t know the max load but so far they works fine.
5:40 I hope you are using stainless steel rivets. Small aluminum rivets will only last a few years.
I hope he isn't I'd be far more worried about bimetallic corrosion than a non load bearing body panel shearing off loads of alluminium rivets
What is a wheel loader and what does it do?
Move things or materials :)
Search on Google Images for "Volvo L150H" to see a typical wheel loader. Loaders typically load trucks, so what they do (mostly) is pick up something (typically loose product like gravel, sand, dirt, stones, etc.), lift it up and unload it into a container, like a truck or similar. They are also called front-end loaders in some regions.
What makes wheel loaders special is the way the arm/boom that holds the bucket is attached to the machine. When the machine pushes into something with the bucket, the force is transferred to the rear axle. When you lift something heavy, the force is mostly on the front axle (closest to the bucket). For this reason, when you push into a pile of gravel, as an operator you can distribute the force between the front and rear axle depending on lifting the arm slightly at certain moments. This is essentially what makes the wheel loaders very efficient; because of this great distribution and traction, they can push stuff very hard (nearly like a bulldozer) but in addition have the capability to lift and dump stuff. In addition, because they are able to achieve this traction using wheels rather than belts, they are fairly "gentle" (for their size) on the surface they're driving on.
Wheel loaders come in many sizes, from almost lawn tractor sizes to huge machines larger than houses. Especially the smaller and mid-range sizes are very versatile with hundreds of different attachments like sweeping brooms, demolition hammers, earth drills, pallet forks, timber grabs, ... to name just a few. So while originally (and mainly still) for loading trucks, today wheel loaders handle a wide variety of jobs.
Otroligt att du inte har fler prenumeranter. Du har bra videos och gör rejäla grejer.
Tackar 🙂
Hi man it was wery good idela how make hydraulic drive systém 🤤. I am trying to build this here in CZ, but, everyone tells me that hydraulic motors will have little power to load the bucket, it will not have the strength to go uphill with the load, max speed will be very low etc…. Can you please reply to this information so I can use it? thank you very much I am your big admirer🤘
It depends on many factors.
For example the size of the drive motors (cc). I use four 170cc. But in my case it would be better with larger drive motors to get stronger machine. My machine is also quite heavy, about 800kg I would guess.
It also depends on how they are connected. All four in series bring permanent 4wd and fast machine.
All four connected in parallel result in a strong machine. But in the worst case, you only get drive on one wheel on slippery ground. Compare with an open diff on a car.
I have taken the middle road. The front motors are connected in parallel. The rear motors are also connected in parallel. Then these two devices are connected in series with each other. This means that I have drive on at least one front wheel and one rear wheel.
You can also use extra valves to switch between series/parallel while driving . But it is more complicated to build.
@@AlfaSeven well, if all motors are connected in series, I still have 4x4, but that doesn't matter, right? men want to know some parameters of your engine and drive pump, I want to use an OMT 500 engine. it has 16mpa 1220nm 240rpm 125l/min and 28.8kw. what pump should i use for these 4 motors connected in series? I want a machine weighing around 2500kg and wheels 400/60 r15.5
Btw: thanks you wery mutch for comunication

My hydrostatic pump is a very old Eaton pump from a machine scrap yard (may be more info in episode 4). It turned out to work decently together with my hydraulic drive motors but it was a gamble. I cannot answer your other questions and must refer you to the internet. Try to find a machine forum and post your questions there. Another idea is to analyze what pumps etc to be find in production machines.
Are you going to use hydraulic oil radiator type cooler?
I want to make solutions as simple as possible. therefore I have chosen not to have a cooler and instead built a slightly larger hydraulic tank (40 liters). Also, it is not intended to be used 8 hours a day. I think it will work well for me
👍👍👍
Show next time please, the finished product a littel longer.
