If you think about it the hydraulics flowing in the lines are relatively quiet. the piston lifting or lowering the boom is just as quiet...so where is the noise ? it comes from the pump and the prime mover for the pump..If its a diesel engine its loud.. If its steam driven ,somewhere there is a lot of fuel being burned and that location is loud...If its run by an electric motor and Even if its just in the bypass mode the fluid screaming through the control valves will be loud...So now ,,,Going back to your question ..the boom is practically silent but the prime mover makes the whole thing very loud indeed. 90-100db at times...
Hydraulic shock from quick closing valves and can cause piping to rupture Hydraulic shock from quick closing valves and can cause piping to rupture
sound can be whatever you want it to be. As quiet or as loud as you want it. To be safe, don't turn the music or sound up too loud because it will/could shatter your ear drums. And also, you do not want it too quiet to where you can't even hear it.
Yes if the installer used the wrong type of check valve as the flapper is reseating
yes, they make a loud roaring noise.
The cause could be your muffler. Mine has a hole in it and when I accelerate it roars, kind of like a vacuum.
Wheel bearing
It could be a wheel bearing or the center carrier bearing of the driveshaft.
The compressor may have a locked rotor in the condenser causing the loud roaring noise. Another possibility is low refrigerant.
I think it's called an engine
Bad fan clutch!!
If applicable, you may have a faulty (locked up) fan clutch.
the clutch release could have broken , the brakes could have locked, the engine could have blown, the transmission could have broken. These are mostly things that have happened to our ranger. It depends what you mean by stops
It turns out that it was a bad idle air control valve. Right after I replaced it the loud noise stopped. About a hundred dollar fix, it was well worth it!
sounds like your back breaks are wore you use them the most when you are backing up.
If you have a clutch it could be slipping. It may also be a problem with the muffler or exhaust system. You may also have a very powerful engine.
