1 SB hydraulic breakersEasier to use, easier to own, tougher than everSB 102: 564 mmFor years, Atlas Copco s solid body breakers have been considered the toughest, most reliable on the market. Now we also aim to make them the easiest to use and why develop a new generation? Contractors are using hydraulic breakers in an increasingly wide range of applications, as they move from handheld to rig-mounted equipment. So, we ve made the new range accessible even for inexperienced users. The result? breakers that are easier to use, easier to install and easier to harder, hits fasterBut rest assured no compromises have been made when it comes to reliability and productivity.

2 In fact, we ve taken the solid body con-cept a few steps further. In terms of impact energy, the new SB's, the first breakers of the new design in the range, hit harder than their predecessors and with 50% higher frequency. Plus, productivity has been given an extra boost by improving operator ergonomics in the form of reduced noise and vibration : efficiency has been boosted thanks to the design of the new hammer hoses at the sideAll hose connections oil in/out, dust suppression, air flushing and automatic lubrication are positio-ned on either side of the breaker , making for neater installation of hoses. This reduces the risk of the hoses getting damaged when wor-king in confined to installEasy to useShort and easy to transportThe new SB breakers are the smal-lest on the market in their respective carrier class.

3 This means they can be easily tucked up under the carrier boom during transportation between noise, less vibrationsThe noise and vibration levels have been considerably reduced. This has been achieved with the help of a new hammer mechanism with recoil dampening, as well as the new compact design of the hammer body. Double tool retainersWith double oval-shaped tool retainers, tool rotation is minimized, thereby reducing wear and tool breakage. The strength and design of the tool retainers ensure that they can withstand blank firing. Simple tool retainer lockThe patented tool retainer lock is robust and allows minimal play. With no small parts that can get lost, the system also simplifies tool replacement.

4 Widest shank diameters The shank diameters of Atlas Copco tools are among the widest on the market. The extra few millimetres gives a stronger, longer-lasting tool that can take much higher bending stresses. Made by Atlas Copco, the tools are the result of many years of experience and offer a perfect balance between hardness and durability. Impact rate boosted by 50% Although the new SB's weigh the same as their pre-decessors they hit both harder and 50% faster with the same oil flow. This boost in efficiency is due to the new design of the hammer to serviceTechnical dataEasy to replace tool bushing The new floating bushing can be replaced on site with standard hand tools.

5 The bushing is protected against oxidation by a patented pres-sure system. This ensures that even after hours of work, the bushing can be changed in the field quickly and easily. A new protection ring keeps dirt out and grease in. Idle stroke protectionWhen the breaker blank fires, the energy of the stroke is absorbed by a piston dampe-ning chamber. This significantly reduces both the breaker s and carrier s exposure to suppression and underwater breakingUnusual in smaller breakers , the new SB's have both a dust suppression con-nection and an air flushing connection (used when working underwater or in extremely dusty conditions). There is also a built-in lubrication channel and a connection for the central lubrication and more compactThe sleek lines of the new SB's make it easier for operators to see the tool.

6 Plus, the compact dimensions make working in confined spaces simpler inside buil-dings, for example, or in narrow trenches. The accumulator is now cast into the main body of the breaker . Not only is this a more robust design, but it also means you don t have to unbolt the accumulator to reseal the hammer tool bushingThe length of the bushing gives greater tool guidance, redu-cing off-line move-ment and subsequent fewer partsThe original solid body breakers contained less than half the number of parts common in conventional breakers . In the new range, that number has been reduced still further, making it even simpler to ser-vice the accumulatorWith the accumulator now cast into the main body of the breaker , you don t have to unbolt and remove the accumulator before pulling out the hammer mechanism.

7 This saves time and also makes it unnecessary to recharge the oil changeIt s now easier for operators to switch between oils when different carriers are being used. Instead of having to dismantle the whole breaker , we have added a drainage port through which you can flush the breaker clean with compressed without toolApproximate Service WeightBlow FrequencyOperating PressureOil Flow RateWorking Tool diameterPart Numbermminkglbsblow/minbarpsil/mingpmmmi nSB 524441755121720-1800150217512-273,1-7,14 01,68460 0300 10SB 1025642287191720-2,280100-1501,450-2, 0300 30SB 15266226140308840-1,920100-1501,450-2, 0300 40SB 20271428200440840-1,800100-1501,450-2, 0300 50SB 552989395201146660-1140100-1501450-21756 5-11517,1-30,31003,98460 0300 0592 01b 2004, Atlas Copco Construction Tools AB, Stockholm.

We make our own grease: it s rich in graphite and copper which gives it high temperature stability for superior downtime, increase lifetime Tools, tool retainers and bushings need to be lubricated at regular intervals.

10 With our central lubrication system, grease is conti-nuously pumped to the breaker . This gives you two advantages: first, you eliminate downtime caused by lubrication stops; second, you protect your breaker because it s always being lubricated ,500-2,600SB ,400-6,600SB ,200-9,900SB ,200-13,200SB ,800-33,100 Choose the right breakerUse only authorized parts. Any damage or malfunction caused by the use of unauthorized parts is not covered by Warranty or Product s hydraulic breakers offer a signifi-cantly improved ratio of percussive perfor-mance to weight, which in turn imposes far greater loads on all breaker compo-nents. The dimensions, material properties and tip geometry of working tools have a major impact on reliability, wear behavior, performance and working tools from Atlas Copco are made from a special alloy that has been optimized for hydraulic breaker applications.
