Durability? Chisel Pin, Thourgh Bolt is Bigger than other companies and improved durability.

? Minimized process of Bracket welding and strengthened durability.Function

? Applied 2 step stroke and Idle blow preventing structure system

? Maximized impact powerSupplementation

? Fixed the problem with Chisel pin looseness.

? No oil losses when changing the control valve.? Prevent vibration between power cell and bracket when assemblingEase of Use

? Simply disassemble and assemble

? Control Valve can be replaced on site speedily.? Easy Maintenance (save the time and cost)? Extend the part's lifeDifferences compared with other company products

? Our product can be handled on site when the control valve have a problem.

? Because It doesn't have to disassemble whole parts, the excavator oil doesn't decrease.

? Because It doesn't have to disassemble the through bolts, the loosening by vibration is less than the existing hydraulic breaker, when operating.? The front cover was designed to prevent crack. the existing front cover is angulate shape but our front cover is round shape.? Stable support system between Power cell and Bracket → Reduced Noise → Minimized the screw loosening by vibration. → Stable operation

Why AY Hydraulic Breaker?? Easy Maintenance on site? Save time and cost? Extend the part's life? preventing falling off in efficiency of Excavator and Hydraulic Breaker → Maximized profits of User
