When you are tripping with the machine, just the weight of the hammer do not lift the machine to apply more weight to the hammer like this guy did it in the video you screw everything up he’s a young kid. I got 40 years under my belt. Driving those machines and chipping and excavating
Great video, some misinformation in the comments. NPK suggests no more than 30 seconds in the same spot. And, you should always lift the tracks 4-6" off of the ground to preload the material. Otherwise you wont break that blue rock. We generally suggest against those type of couplers, because when they fail, broken parts are spread into the hammer ans excavator. We suggest using Stucci or Roflex couplers which thread together. They are more robust and if they fail, they shut. Greasing once per hour, always with full pressure on the tool.
What the suggest for greasing and brand for this breaker?? Mine using high temp grease but not work properly, grease still liking like oil. Need suggest frlor type and brand grease. Thanx
Yes your definitely hammering too deep, just hammer a little just to crack the concrete and go to the next spot, its tricky with rebar as it holds it all together, its a pressure game, good luck
Morning just seeing this question. Please be careful with rebar as it can whip around and injure u someone else or damage ur machine or other equipment or property. As for hammering I have found that making minute adjustments while hammering usually leaves the chisel with enough room for its withdrawal. Also its recommend that u do not engage the hammer for more than 20-30 seconds which should reduce the chisel getting stuck unless u r hammering a semi hard material causing hammer to pass thru quickly. Pray this helps u. I hot 30+ yes experience in Bermuda.
video ok one thing you missing totally and that is the settings part of the hammer attachment.you should take down the camera and focus it on the screen so that we could see fully what you was doing,but over all I like the video cause soon ill be operating,I would appreciate it if you could do over this video and include the part I told you to ok,thank you brother and continue to make videos for the world one love ,
Greetings one Very Important thing which you Failed to mention is Before you start using a Hydraulic Hammer you should Grease the Tip and detail the proper way of greasing the hammer tip effectively. No offense intended just think it's a Very Important piece of info which should be shared. Also it is advisable when hammering for extended periods / hours, I will grease the tip more than the 1 time at the beginning. I have 30+ years operating experience with various machines. Also when explaining that you should not pull the hammered material, because you can break the tip / Chisel as it gets extremely hot.
Been Hammering since I was 15. I’ve used a verity of hammers and even broken a few. That’s a cool feature it won’t let you dry fire. That is very bad for the hammer it happens sometimes when you break through boulders. I’ve never greased the tip seems like a waste of grease to me but to each their own. Each hammer is different but my experience is grease every hour on the internal 30 pumps. Some hammers require a specific type of grease. Over time you learn to read the rocks lol in order to break big rocks you need to chip away the edges until you can get to a seam or use the rocks weight against itself. Now I’m that guy on the internet hahaha anyway if you’re hammering for a trench you should go as wide as possible the ledge will always want to V in. Finally get yourself a good half inch shield of lexan do not clean with glass cleaner research the best way to clean it certain chemicals will fog and swirl the expensive bulletproof lexan shield. Also they make socks for the pistons otherwise it will chip em and ruin your seals on your boom pistons. 10 hour days of non stop rock smashing will break your brain and you’ll end up on RU-vid talking about it be advised sir 😂✌️
Every time I talk about buying a hammer, everyone says they destroy the pins, shake your machine apart... one of my friends spent $1,000 a day to rent a whole machine with a hammer. And he has an excavator. Do they really drastically lower your pin and bushing life?
I've seen machines with many thousands of hours of hammering still in good condition. It comes down to machine maintenance and operator competence. Yes it increases stresses on the machine but nothing that a high quality machine can't handle.
Been Running Hydraulic Hammers for awhile and Yes it does cause some wear on the machines but if you're running a quality machine like a Cat, Komatsu, Case, Hitachi, Takeuchi, or Yanmar, then you won't have to many issues. Those machines are built to last and will run Hammers day in day out for years. But if you're running a hammer on a low quality machine then it will fall apart very fast and won't last. Just get a Cat or Komatsu and you wont have to worry, they are worth every penny.
@@WesD808 I had a takeuchi 35, now got a kubota 25. My neighbors got a cat 315, I'd like to get one of them. Seems like the perfect size machine. Thanks for the response.
Thanks for this man. I'm getting ready to rent a mini excavator with a 1500lb hammer to bust up some limestone boulders in my yard. This was very helpful
Maybe it is in our culture, but few things i see when hooking up the hoses of the hydraulic hammer with a wrench: no safetyglasses, no helmet. I would not feel so safe when manipulating with a wrench, if something happens, the hydraulic pressure is over 400 bars. GReetings from Netherlands
You should replace the Hammer with a MB-R Drum cutters. They work very well with excavators and do the same job with less arm strain, more precision, less seismic activity AND everything it comes in contact with gets crushed to 4'' and minus.
And hammer no longer than 10 seconds at a time or they will overheat and it will break the tool/pin or blow the seals out of the hammer break for 10 pause for 3
I was hoping to possibly add to my hammer knowledge by watching this video. Unfortunately I found it a bit disappointing. I thought that this video was generally informative but there is (at least in my opinion) a lot more critical information to hammering than what was presented. Hydraulic breakers can be a very expensive tool to purchase and can be very expensive to operate. Especially of not operated correctly. A critical addition could be to talk about what techniques could be used to prevent premature wear to the hammer itself. There is actually some information given that I would disagree with. I almost didn't post a comment as I feel bad about not posting a positive or up lifting comment (especially in a public forum). Hopefully I haven't offended HML or Wesley. BTW, if you someday find that your machine begins to get hot while breaking (higher hydraulic temps and then possibly engine temps) consider using Stucci couplers or maybe just go to no couplers for the hydraulic hoses.
Appreciate the comment. Absolutely open to feedback and constructive criticism, so thank you for being respectful about it. I think you make some very valid points. Honestly I don’t have any experience with breakers so I enjoy hearing feedback from others. Thanks again!
I also liked the video but similar to @Jason Chapman's comments mentioned I am very interested in learning how to pick the correct size hammer for the excavator. I see that they are typically sized based on the weight of the machine... I'm guessing. Possibly HML could go over how the hammer was sized, the cost of it, and where it was purchased. Other than that, great video, I really like the resolution of your camera...super clear. Nice work!
I find that the quick coupler seems to restrict flow, some need to be repurged with nitrogen. I'm sure after this week I won't want to hear the word hammer. Fortunately I'm unloading the blasting mats on Friday. Here comes the boom
