Introduction of excavator telescopic boom with bucket:
Introduction:
Excavator Telescopic Arm, also go by Telescopic Dipper Arm, is a working device installed on the excavator, usually work with clamshell grab or other grab buckets. It consists of the fixed body and the mobile body that can extend and retract the mobile body through the action of the telescopic cylinders, to achieve a larger excavation radius and a reasonable loading height. This type of working device is called a telescopic arm.
Application area:
Widely used in the construction of urban streets such as subway excavation and foundation pit excavation of viaducts. Working under limited radius.

Quality Control--professional, more accurate, high-effective:
Post-welding Testing
Accuracy Testing
Weld bead testing
Testing before send out goods
Operation Testing
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.
