Air tools operate at around 20 - 28% efficiency on energy input. That means a 32HP diesel engine is required to power an air breaker, for same hit power that hydraulic breaker does with a 9HP engine, because hydraulics operate at around 73 - 82% energy efficiency. Ask yourself this, have you ever seen an air powered excavator? Neither have we ......it's hydraulics that make it happen.
In order to really clarify this, let's look at nature, it designs everything based on natural selection and efficiency, anything that fails in nature becomes extinct. Your Father used hydraulics in order to ensure he had the means to insert seed. If air was that good, his lungs would be used to fill the chambers that make boneless flesh hard, it is actually blood under pressure, hydraulics that do that. Which is why the heart rate rises and blood pressure increases when we get excited. It's a reason we love our hydraulic tools.
Short of coming out to your premises and comparing them with any competitors machine, if there is or was one, we will look at facts, performance, feedback and our own experience. As we own, have owned, used contractors with the equipment and/or hired this equipment in on our own projects, plus we would not hesitate to bring any of it in on a job tomorrow, if we had one, that should be proof enough, however!!!

They are highly profitable job winners
They actually do not do the same job, yes both cut concrete, but the method and production rates are totally different, as is the reasons for using a ringsaw instead of a track/wall saw. If you have a saw cut to do that is say, 250mm deep for more than 5 metres in length, we would use a track/wall saw, if it could be used. Often access makes it difficult to do so. Other consideration is the physical toll on operator. For deep mass concrete you could wire saw it but splitting it is faster and more economical, you could also use a hammer to break it up, are there noise or vibration restrictions? You really need to evaluate the nature of the job and choose from what equipment is available, the correct option. Cost is a vital factor, does the client have the money, did they underprice it at tender stage? As they say in Thailand, same, same but different.
We sort of covered this earlier in the bit about saws, it comes down to cost, site conditions, restrictions in place and access, one or all can dictate what NEEDS to be or should be used.
Noise and vibration are two major obstacles to using an excavator with a hammer, access is also an issue, can you get the excavator into where it is needed? We look at it like this, what is the material, where is it located, what is the fastest most profitable way of doing the job? Two splitters, hoses, enlarging wedges, core drill, saw, ringsaw and packs to power them would cost less than $80,000. An excavator in the 5 ton range, without any attachments cost more, needs a truck to move it and has limited ability, it will not break granite.
Profitability is up there in reasons NOT to use a hammer. An excavator was designed to dig, hence name excavator. No one calls it a breaker or hammer carrier!!! Every time you use a hammer on an excavator, the slew gear, bushes, bearing, welds and everything else, including the operator, suffers from fatigue and vibration. These eventually fail and can be expensive to replace or repair.
There is a long list of advantages of having hand held tools. We firmly believe that the range of work you can undertake, in even the most isolated of locations or in the hardest rock you can find, results in more work, higher utilisation = greater profits. You can work in road or rail cuttings, demolishing unstable rock, or work in a hospital that is occupied and has noise restrictions but still break concrete, quietly.
Look at it this way, a basic kit of a Hycon petrol pack, core drill, saw and 23 Kg breaker would not cost a fortune but to undertake work with them, or hire them out, would give an excellent return on investment, simply because of the easy tranportability of it and the range of work you can do. Add a Darda splitter or two and a set of HCS6 Combi-Shears to the kit above, you have just taken it to a whole new level, in ability and capability to widen your range of potential work that can be done. The beauty is you can keep adding tools to the kit, post driver or post borer means you can do work for a fencing contractor, the possibilities are endless. We think the best part is, they do not cost a fortune to own, run or maintain and you can do a LOT of profitable work with them.
If you have a carrier machine between 0.9 - 15 ton, you can use the same attachments that are applicable to your carrier weight. What you cannot do is send your excavator and operator into a hot kiln, dangerous area with risk of collapse, or anywhere that puts the operator at risk. A Brokk operator stands back in a nice safe spot and controls his robot from a place of safety.
The other very important thing to note is the Brokk's ability to climb stairs, go up in service lifts, go through narrow doors and work in areas an excavator cannot get to, model dependent of course. Most of the available attachments, crushers, steel cutters, hammers etc. were designed for use on excavators, it just so happens a Brokk can do a lot more work than an excavator many tons heavier and bigger than they are. Working in areas an excavator simply cannot go.
The first time we worked on a rail track, it was while reducing the size of big floaters and rock stabilisation in railway cuttings, using Darda splitters. It was the first time we saw these types of track maintenance machines and equipment in action, so we had a play with them. As our interest is in hydraulic machines, we took an interest in what they do, why they are used and what they are used for. Later, while working in the rail industry in the UK, we trained on these machines and operated them on various track renewal and stressing jobs.
With very recent knowledge of various machines on the market, using them, comparing them and specifying which to purchase, it made sense to include them on this site. Sharing knowledge and experience, does help many people make informed decisions. Our decision to include rail equipment when upgrading the site, was a logical one.
