Wow, finally someone who can explain the way the dam thing works. I once did a summer internship in a local heavy equipment shop and the mechanics kept telling me that "the chisel doesn't move", which made no sense at all given that a hydraulic hammer is triggered by the weight placed on the chisel by the machine. These guys even got belligerent with me and told me to stop asking questions from what I can remember. Thank you so much for posting!
You're not quite right in your description. The tool (you call it a chisel) does not push the piston up into the nitrogen chamber. This is done with hydraulic pressure. If the tool and piston move together as a unit there would be no hammer action. The nitrogen pressure acts as a shock absorber for the piston and helps the piston to start it's downwards stroke until the hydraulic switch over valve has switched over from pushing the piston up to forcing the piston down onto the tool. It is important to push the tool back into the hammer before starting the hammer, if it is not then the piston will dry fire (not hit the top of the tool) and may get damaged.

I have a brok machine sb 202 epiroc breakers the problem i faced is that the breaker stroke is not working properly the stroke is very low means stroke pressure please suggest me some causes so that i able to repair it.
does it mean on the first stroke that as long as you press the breaker on a rock and there's pressure, it's not necessary to use the hydraulic control valve?
That first stroke story i badly told. It's not a stroke. It's only the nitrogen giving more and more backpressure the harder you compress it. It's not like the nitrogen is giving an impact on the rock more than the excavator is pushing on it. It's exactly like compressing a mechanical spring but then with nitrogen. As long as no hydraulics are activated its not hammering. The hammering is apparently caused by ports in the piston which have a small offset compared to holes in the cylinder, which makes the piston move back and forth.
Hi Dilip Good question. Speed depends on flow So when you combine another operation while operating breaks, the pump now have to supply flow to multiple operators resulting in less flow to each operation resulting in the breaker to slow. And at the same time when you have multiple operation the operation which has the priority will get more flow depending on how the circuit is designed. Hope it’s clear, please feel free to WhatsApp me @ +642102936490
We have some hammers which hang vertically (3 in a row) and they suffer with dry firing. If we put the pressures up to 14 bar in the accumulator they struggle to fire, so we drop them to 12/13 bar and they will fire correctly until the system has warmed up to 52-55 degrees and the dry firing starts again. System pressure is 145 bar and fixed flow through the use of pressure compensated flow control valves. The model is a CP400 (Chicago Pneumatic). Could you also explain which surfaces the oil acts upon to fire the hammer up and down?
@@TechTrixInfo you said in the vedio it's not works without surface contact but now Dozco 2200 will run with or without surface contact but d135 will only run with surface contact why???
@JayPrakash-pr5qm Hi Jay, Thanks for the question, that means it’s might be a different mechanism compared to what I have explained, there are different types in the market, will have a look and get back to you, have a good day, stay positive, stay kind
Hi there thanks a lot for the share,i have few doubts ,how is the control valve contorlled,can u share how the valve works and will u please explain the rock breaker hydraulic circuit.
Don't mind if i asked, i used to install a hydraulic breaker to some customer. I'm gonna be honest, I'm new on this industries. I found out that, some of the breaker after installed. work for couple 100 hour it stop functioning. Customer did said that, after the excavator heat up. the breaker won't even moving and getting power down. is there any big problem? the measuring pressure were put accordingly to guide. is that the viscosity of hydraulic or or internal problem? sorry for my english
Looking into a bobcat skid steer break. I was told it'll work for a bit. When it stops, you have to back flow the hydraulic flow. Then it'll maybe work a little longer. I believe they did charge the nitrogen once. Where's first place to look for a fix?
I will be buying a rock breaker I have questions the one company is saying their workin of breakertechnology is 70:30 % ratio of gas and oil and another one is vice versa pls tell me the difference between them and which one is better
Hi, very interesting video, i work with hydraulics a lot and was wondering where you got this principle from? the hammers ive been working with are different (montabert brand that is), there is a component termed a distributor which is similar to that of an additional piston, in place of the 'head cap' that you term, when flow passes through this distributor it moves in the opposite direction until it goes far enough that another cavity pushes it back the other way, all the while hitting the
Hi Suraj, I too have a same doubt. what kind of reaction and how much reaction will be there on the hammer bracket during the operation ? I request admin to help us understand this.
Yes you're very right , on head cap you first screw in the check valve then fill ,then on accumulator you first unscrew the nut then access the alen key bolt ....
Wow I've never before watched a youtube video and not actually learnt anything. This is so bad he doesn't actually explain what happens in a cycle, he just writes numbers and draws arrows.
Sorry but that's a rather vague explanation of HOW a breaker works. There is absolutely no detail in the valving and hydraulic flow explanations, therefore it really is not explained how it works.

This guy is an amateur.
Thank you, i believe you are a technical person.
PLease have a look at our other videos too and rate it.
Demonstration of working of a rock braker is very good.I like it very much.Thank you.
Thanku for this valuable video. Please make i video of practical. This will more easy to understand

Great, please refer about us to your friends too.
very good demonstration. it has augment to my understanding of the operating procedure. thank you.
Now we came to know how the breaker is working.
Thank you sir
See breaker is a simple unit, just make sure that the Gas pressures are as per the manual. will get a expert advice on this field issue and revert.
Thank you bro
Welcome, thank for your support
Very important information for me thank very much

Amazing, dude.
good shows.breaker are so easy.
Thank you for posting this info. Very helpfull
If this mechanism was to be condensed into a smaller model, would it still be able to exert the same pressure, or something similar?
Thank u nice sir

Good Narration,
thanks 4 ur info .....
Good nd helpful

Which breker is better dyframe or plane
Hi, do you any idea of converting mechanical to autonomous rock breaker
what is purpose of breaker head, control valve, liner.
i saw sb702 breaker have 2 bush tell me why ?
does it mean on the first stroke that as long as you press the breaker on a rock and there's pressure, it's not necessary to use the hydraulic control valve?

thanks a lot you are great
Thanks for the useful information and video, expecting more thanks again
Sir why did the breaker geates slow while we operate the other fansion during breaking and head gas geates high
Hi Dilip Good question.
Speed depends on flow
So when you combine another operation while operating breaks, the pump now have to supply flow to multiple operators resulting in less flow to each operation resulting in the breaker to slow.
And at the same time when you have multiple operation the operation which has the priority will get more flow depending on how the circuit is designed.

is there any big problem? the measuring pressure were put accordingly to guide.
is that the viscosity of hydraulic or or internal problem?

Hello sir
Plz tell me working pressure drop issue
Thanks
how that back pressure is produced.
how that tool move up and downwhen applying pressure to the nitrogen
I will be buying a rock breaker I have questions the one company is saying their workin of breakertechnology is 70:30 % ratio of gas and oil and another one is vice versa pls tell me the difference between them and which one is better
continued - all the while hitting the tool and then reversing and hitting a nitrogen filled chamber (accumulator with a diaphragm)
could you please answer my question? does the power of the operator pressure affect on the operation or not? i mean the pressing pressure
The operator pressure is needed to place the hammer in position and give a light initial pressure.
