Heavy Duty Rock Arm For Sany SY500 With Excavator Ripper

Kaiping Zhonghe Machinery Manufacturing Co., Ltd, a leading Chinese excavator manufacturer, is proud to unveil its versatile heavy-duty rock arm, also known as the burst arm, eagle beak arm, and excavator super hook.

The heavy-duty rock arm is specifically designed for excavators to handle the excavation and crushing of weathered rock and shale. Unlike standard-arm rippers that are limited in functionality, and breakers that often have lower efficiency, this rock arm provides optimal performance, meeting engineering needs while maximizing profitability.

Operating with exceptional efficiency, the rock arm significantly reduces crushing costs and maintenance expenses compared to traditional blasting operations. Its versatility and robust design make it a cost-effective solution for various excavation and crushing tasks.

Kaiping Zhonghe Machinery Manufacturing Co., Ltd continues to prioritize innovation and customer satisfaction, offering cutting-edge tools that enhance productivity and profitability in the construction industry.

✅Rivers cleaning dregging project

ZHONGHE triple quality control system

The first system is the technical design drawing review mechanism,
The second system is the semi-finished product review mechanism,
(each process has a detection testing for the previous process),

The third system is the finished product testing.
(Before painting, the overall inspection is carried out to check whether the design size matches the welding size, and whether the installation size meets the design requirement.)

To sum up, every single ZHONGHE product has been passed the above three-stage inspection system to ensure that is qualified before shipping.

Usually use 40GP container to load product !
