Only a special type of the human race can admire the information in this video. The curiosity of the youth is headed the wrong way. Flawless video sir.
Thank you Carl for your expertise and easy to follow tutorials. As I retired from the workforce and started playing with heavy equipment I had limited experience on the hydraulics I soon started my search and knowledge your lunchbox sessions became my go to ! I recommend them to anyone that has equipment Thanks again from Prosser Wa
Excellent video and excellent teaching skills......Greetings from Pakistan.......Just i would like to add that same joysticks were used in old fighter aircrafts to control FCS. Now, modern aircrafts still rely on same hydraulics but with slight modifications in control i.e when pilot turns the control column /joystick, command goes to the ECAM that performs same pilot operated function )(hydraulics), commonly known as "fly by wire " system.......Please keep us educating......Once again, thank you very much for sparing your valuable time....
Honestly, I just finished watching it. And I've almost watched the past few episodes as well. It is a great help to further develop this understanding. Two years ago I was an Engineering technician at an Industrial plant for over two years. Almost all mechanical motions are hydraulic. As I watched your videos, it came to my mind again. Thank you for this teaching of knowledge. I'm from the Philippines. And now I'm a Service Technician in a Company.
Ah , yes Sir.... As of now , nasa isang Company nmn po ako na ang mini maintenance ay mga Srew type Air Compressor po. As part of my scope of work. Mostly sa Electrical works po ako (Motor Control , Electromechanical , Electrical Power Supply , Etc...) Since , 2014 nagkaroon na po ako ng interest sa Hydraulics. Till now... Kaya halos nakasubaybay po ako dito. Nice to met you Sir. Keep safe.
I love you guy. You have deliver the subject precisely. I wish that it will continue in the future to educate and shre knowledge to interesting people. God bless your company, the team that make this video possible. Thank you very much.
You people who are involved in making these amazing resources are excellent and amazing in explaining and sharing your knowledge. God Bless you All. Love from Bangladesh
I would really enjoy a video for pilot operated joystick controls for large excavators. (Mine do not have a tank connection at joystick). Hamworthy/hydreco system.
Hello carl! Thank you so much for your demonstrations. Actually I've been auto,truck,and heavy equipment mechanic over 5 decades but,your video and instructions excites me alot. I have learned a lot and made me a compident hydraulic technician. You enlightened all my questions about hydraulic system.May the almighty god Jehovah bless you.
I would like to say you cleared alot of things I was trying to understand. If you please if you can explain more stuff regarding Komatsu hydraulic system. I'm working with Komatsu every single day
Cool video presentation Do you know when and where hydraulic pilot servo control first appeared on any kind of equipment, mobile or industrial? I know Monsun-Tison (today Parker) introduced the HVP2 pilot control valve around 1973. I also know that Åkerman (excavators) had its own pilot control valve on the full hydraulic excavator H11 in 1965. But before that, I have only seen pneumatic pilot control on an excavator from the early 1960s. Åkerman is today Volvo CE owned. I know the airplane technology used pilot joystick controllers but that was for closed-loop "position control" of rudders ie rudder position proportional to joystick lever position. For mobile hydraulic crane and excavator applications, we are working with actuator motion "speed control" proportional to the joystick lever position.
Hi from India. Could an orifice really control the speed of oil in the pilot line opening a pilot check valve and make it slower than it was before using an orifice.
if we block the pressure reducing valve , will we get reduced pressure , or is the main spool spring will determine the reduced pressure ? Thanks for clarifying
Thanks so much. Im from algeria . I want to ask , example that we have fully contaminated system how can we clean it and solve the issue. System contains tank long hose valve bank directional valves cylinders motors.... sun hydraulic cartridges
hi.. can you tel me a bit mor about joistic control supply... it is clear for pressure but what about flow? and from where usally is taken this flow, from gear pump ?
Greetings from Phil.nice you tube channel,very informative.In yourPilot Press Control video,the main hyd valve is just common hyd pilot valve?or it is a special valve to match the Pressure Reducing Manual Joystick valve?Thanks for these tutorial.
Wesley Hibner we do work to keep the fittings leak free (minimal tapered threads) and our shop (the RU-vid Live set) is very clean. But if we take our equipment on the road then the dust does start to become an issue.
