A large number of construction machinery are needed in municipal construction, subway and sewer reconstruction, river cleaning , etc, but standard excavator is not capable for these engineering program.In these situations, it is necessary to use the extended-arm excavators , which can be used in dredging, slopes, and subway construction,etc.
Zoomlion Long reach excavator is improved on the exsit mature model. Through advanced 0computer-aided design system, combined with Zoomlion’s more than 20 years of experience in the design and processing technology of extended-arm excavator, the finite element method of the stress distribution of the extended-arm is used to optimize the structure of the extended-arm to ensure the stability and reliability of the arm. Beside that, we have optimized the ECU program of excavators to ensure the best working efficiency and fuel economy.
