①N2 Gas Charged Accumulator
Rechargeable N2 gas accumulator to assistpower stroke and to reduce the surgepressure and the spikes from the hydrauliccircuit of the excavator.
②Auto Grease Refiller
Compact auto grease refiller isequipped as an optional feature.Easy daily refill is serviced and continuous greasing is available as long as the breaker is operated.
③Piston
Most efficient design for maximumenergy transfer and recoil reduction aswell as ideal match of tool and pistondiameters. It transfers highest shockwave into the breaking objects.
④Symmetrically Rotatable & Soundproof Housing
180° rotating housing will extend thelifespan of the housing from the one sidewear. It also proves to save the operatingcost with such conversion.
⑤Underwater Application(UA)
Air line for underwater use
⑥Super Anti Blank Firing (SABF) System
SABF increases the lifespan of allcomponents subject to wear andfatigue and reducing stress for thearm of the main carrier and thebreaker. (Not shown on the illustration)
⑦Dual Tool Retainer Pins
Correct tool alignment and dispersionof tool wear.
⑧Housing Bottom Plate
Abrasion-resistant plate deliversbreaker protection.
⑨Working Tool
Heat treated and optimallength for efficient breaking.
⑩Field Replaceable Tool Bushing
Convenient for field replacementand protect the front head.
⑪Dust Protector and Replaceablelnner Bushing Sleeve
Option package : dust wiper seal andinner bushing sleeve are also availableto save the operating cost down.
⑫Wearing Plates
Employment of wear resistantplates between cylinder, front headand housing increases the overallproduct durability.
⑬Side(Tie) Rods
Fully closed side (tie) rodsenlarges the durability and theoptimal load carrying capacity isdesigned.
⑭3 Stage Cylinder Design
3 stage rounded cylinder designimproves stable operation toincrease the product durabilityand to reduce the unnecessary-damages such as scratches.the flow variations.
⑮Double Side Buffers
Side vibration absorber and sidesuspen-sion device to protect thepowercell. Convenient installationand replacement for easierserviceability.
⑯Check Valve (Oil Back FlowControl)
Prevents back oil flow and reducesunnec-essary pulsation spikes fromthe hydraulic circuit for the stable operation.
⑰Top Buffer
Vibration absorber to prevent theimpulses between the carrier andthe breaker.
⑱Efficient Power Transfer(Piston to tool)
Optimum transfer of blow energyinto the material and the reductionof the recoil.※Note : some features may be adjusted due to the drawing updates by the manufacturer.
