#Keyword : Hydraulic breaker, Excabator, hammer, top box type, internal side type, skid loader, foot-operated valve #About AY HEAVY INDUSTRIES CO.,LTD AY heavy Industries is growing to become the company continuous developing and challenging with know-hows from our professional engineers regarding the business ofHydraulic Breaker, Compactor, Crusher, etc. And also the company is hittachment, Skid steer loader attachment, Construction Machinery, Excavator Attachment, Skid steer loader attachment # Strength Easy Maintenance when it has a problem. We have a listed patent on this technologies as well as design registrations also. If there is a problem with the control valve, the hydraulic breaker is not working. The existing breaker should be moved to the factory and disassembled whole parts to change the control valve because it has the control valve in cylinder. when the breaker is being disassembled, there is a lot of oil leakage that is causative factor in decline of efficiency of excavator. However, AY hydraulic breaker doesn't have to be disassembled whole parts because the control valve is located in head cap and also can be changed the control valve on site only loosening the two bolts so there is no oil leakage. In conclusion, customer can save time and cost, the part's life is extended because minimized disassembling to change the control valve and it is prevented falling off in efficiency of excavator and hydraulic breaker. Stable support between power cell and bracket (have a patent with this technology) when the power cell and bracket join together, certain support system is needed between them. Because our support system is tapering shape, so it enable power cell and bracket to stick together solidly even if there is an error when producing. It can help to reduce noise, minimize the screw loosening by vibration and stable operation. # Youtube : # Certificate : CE, ISO9001, ISO14001 Certified.
