Tips to Get the Most Out of Your Rock Breaker

YuchaiHI supply professional and honest service.

Designed to break large rocks, rock breakers or generally called as hydraulic hammers, as an attachment to backhoe loaders, excavators etc., are generally used in the mining industry where oversized rocks are too large or hard to be reduced in size by a crusher. A hydraulic hammer to break rocks and a boom (arm) are two major components of the rock breaker. There are two major types of rock breakers i.e., mobile and stationary, typically placed on a pedestal or slew frame.

Generally, rock breaks are used to perform various tasks. These include...

1. Rock mining without blasting: Rock breakers are used for primary rock mining to increase productivity and save time. The rock breakers can in fact reduce the load on the primary crusher, thereby, increasing the latter&#;s output. Rock mining without blasting is also environment-friendly as the blasting emissions are eliminated. Also, this method boosts safety at the site as there are no flying rocks in the air.

2. Secondary reduction: In cases when the blasted rock is too big to be handled by loading equipment or the crusher, the importance of secondary reduction comes into play. Even with the most advance blasting techniques, it is inevitable that there will be oversize boulders and these need to be broken as economically as possible. It is in such cases that rock breakers come handy than the crusher.

3. Demolition: Rock breakers are very much suited for the demolition tasks. They are commonly used to break down concrete structures.

4. Other uses: Rock breakers can also be used for other operations such as tunnelling and excavating and trenching.

How to get the best out of the rock breaker?

Keeping in mind the functions performed by the rock breakers, it cannot be denied that they are an important attachment with backhoe loaders or excavators and need to be maintained well to give good results. Here are some top tips to get the most out of your rock breaker...

1. Visual inspection of the rock breaker: It takes only few minutes to visually inspect the rock breaker for any wear and tear. Visual inspection should be done after every use of the rock breaker. This can help you identify any worn or damaged components and prevent unexpected downtime. The visual inspection checklist should include checking hydraulic hoses, the breaker shell, attachment pins, tool retainers and locks and the tool point for any cracks or gouges.

2. Greasing the equipment: This is an extremely important step because it helps in lubricating and clearing the tool bushing area of debris. Thus, rock breaker should be greased at regular intervals. When greasing the rock breaker, manufacturer&#;s recommendations should be followed. To quote an example, there could be seal damage or even a catastrophic failure if the grease is added before properly positioning the breaker. Another example could be that too little grease could cause the bushings to overheat, seize and damage tools. Ideally, greasing should be done every one to two hours to reduce build-up, tool wear and bushing wear.

3. Inspecting the nitrogen pressure: Some breakers feature nitrogen gas assist systems that work with the hydraulic oil to accelerate the breaker&#;s piston. In these cases, it is necessary to maintain and fill the nitrogen reservoir as needed for consistent power and output. The proper nitrogen charge pressure depends on the application and outside working temperature. The nitrogen level required for breaking rocks is different from what is required for breaking concrete in a parking lot. Here, the attachment&#;s operation and maintenance manual can come to help as it will have the mentione about the nitrogen pressure setting for your application and working temperature.

4. Performing regular checks: It is necessary to regularly check the wear status of chisel, bushes and chisel pin. Excessive wear of bushes and chisel can cause chisel head and piston damage. Rock breaker parts are easily available in the market and they can be bought to bring back the rock breaker into a good working condition.

5. Servicing the rock breaker on a regular basis: The durability of the rock breaker can be increased by servicing it on a regular basis. Rock breakers can be repaired or rebuild to give good results.

Apart from the above, the other few things that should be kept in mind include:

1. Always follow the rock breaker specifications written in the owner&#;s manuals, catalogues and brochures.

2. The rock breaker should never be used in a &#;lever&#; motion. Also, the rock breaker should not be dropped on the object which is to be broken as it can damage the rock breaker and the equipment on which it is attached.

3. The impact point should be moved from the edge to the centre for achieving best working efficiency.

4. The tool point should be matched to the respective application to significantly maximise jobsite production and extend the breaker&#;s life.

5. In order to effectively break material, each breaker must be properly sized to a specific carrier&#;s performance. Energy can be displaced and this can diminish the breaker&#;s impact on the material, if the breaker is too large for the carrier. Alternatively, if the breaker is too small, it can put excessive pressure on the working steel and other mounting components, thereby, causing damage.

Thus, by following the above-mentioned tips, you can ensure that your rock breaker gives maximum result at the jobsite and its life is extended considerably. While there are many companies which manufacture rock breakers which are very efficient but one that deserves a mention is Mahindra Construction Equipment&#;s (MCE) rock Breaker.

So, it is right time that you arm your fleet with the best rock breakers to keep up with the growing demand.

With the last month of the year upon us, and waiting to see if Bonus Depreciation will be approved yet again, some of us are out looking for equipment to purchase either for tax purposes or to get ready for next year.  Often times, this is when People look at attachments that may make a good addition to fleet diversity, but please be careful when doing your research.  

If you are purchasing an attachment to be used more than two to three times a year, it is probably wise to look for quality and at a good price.  Many times, this quality comes from Equipment Dealers, not internet deals.  Often times dealers will represent attachment lines who have good support, a solid base of operations, and an ample stock of parts to keep their nationwide network running smooth.  I was looking online at some of my competitors this morning and realized how easy it is for a consumer to be fooled by some photo shopping and smoke and mirrors on the internet.  The picture I am referring to is a hammer company who posts a picture of their hammer working on an excavator in a quarry.  If you zoom in, the excavators bucket pins appear to be oval, almost rectangular.  Also the hammer logo appeared very bright.  Unless you have ever seen oversized oval pins for an excavator bucket, its safe to say its photo shopped to give the illusion that their hammers can withstand the heavy duty work conditions of a quarry.  

Questions to ask when calling around for quotes.

1) Does the website look legit?  You can tell when a company used something like godaddy or actually have the budget to hire a professional design company.  I am not saying that you have to spend money on a good website in order to have a good product, but it simply begs the question... if you can't/won't spend money on the website that is the main representation for your product, do they have the budget to stock parts and support you when you are down?  Thats when they money you may save comes back to be very expensive.  You may save 20-50% on an internet deal, but when you are down for 2 weeks waiting on someone to get you parts....how much does that cost you?

2) If you call to get quotes, ask them for references....and call them.  The main players in Hydaullic Hammers have a number of dealers that they can use as a reference point.  If they claim to just go direct to save you money....what that means is they do not offer the support for their product that dealers want from their vendors.  So if they cant support a dealer, how can the support you?

3) Ask to see a picture of their warehouse.  Ask them how much inventory they keep on hand as well, and get proof.  Many times, you would be shocked at what lies behind some of these websites.  Many times, its a "warehouse" that may be no larger than the shop out behind your house.  They have a connection overseas, and keep light stock on hand to meet some orders, but the parts could be ordered as needed and they often come from overseas.  If you were going to buy an attachment from a garage, why not look at your local garage sales instead?

4) Often times, you get what you pay for.  If its too good to be true, it probably is.  If a GMC costs 45,000 new, but you find a car company online called XYZ Motors and they claim to distribute their own vehicle but it literally costs half as much....whoo do you call when it eventually breaks down?  The rule of thumb is: Fast, Quality, and Cheap....pick two.  If you get all 3, it could be fishy.  Stick with your local dealers or at least buy name brand rebuilds where at least you can find a dealer down the road or be buying from a manufacturer taht can tell you where to get parts and support quickly. 

5) Ask if they are a member of AEM- this is the voluntary governing body for hydraulic hammers.  It is a voluntary membership, but usually members are legitimate hammer companies.  If they are not a member of AEM, keep looking.

Happy Shopping, Merry Christmas, and Happy New Year.  Good luck!
