The reconstruction and expansion of Jiangdong Avenue and the EPC project of underground comprehensive pipe gallery undertaken by Dongzhu Ecological Development Co., Ltd. are the main development axis of Hangzhou Dajiangdong's core industrial park. In the first bid section of the project, the Infrastructure Construction Group Co., Ltd., which has the first-level qualification of the national foundation professional contractor, is responsible for the construction of the foundation works. Due to the high-voltage cable laying of the National Grid, the construction period is tight, the tasks are heavy, and the quality requirements are high. The ZDG650 hydraulic grab of Zoomlion was used for the construction of the foundation to participate in the construction of the diaphragm wall. During the construction process, the Zoomlion grab showed the characteristics of stability, efficiency and precision.

The equipment was officially delivered to users on November 30, 2020. During this period, the actual work was about 7 months except due to factors such as the Spring Festival, the epidemic, and site shutdowns. It has been in normal operation for more than 2500 hours. The three construction sites of Hangzhou, Shaoxing, and Xiaoshan have achieved this. The total output value exceeds 30,000 square meters.

The full-time service engineer provides a 24-hour nanny-style full-process follow-up service for the project to be completed on schedule. During the continuous operation gap of Zoomlion grab, full-time service engineers use night to guide maintenance and replacement of worn-out parts. The construction period of one day has never been delayed due to equipment reasons. This has created value for users to the greatest extent, and the good performance of Zoomlion has been achieved. Highly recognized and unanimously praised by users.

Zoomlion Pile Worker is one of the earliest companies in China to develop and produce hydraulic grabs. The ZDG650 hydraulic grab adopts a classic special chassis, which is powerful and stable in quality; it has a built-in swing correction device and a 9-meter long bucket body. To ensure the quality of the groove, the vertical accuracy of on-site ultrasonic testing is 1/500.
