Recently, Jiangsu Great Crane Machinery Co., Ltd. (hereinafter referred to as® "LDT"); Company” ）The robotic arm underw©ater fixed-point soil sampling robot, which participated in the construction, officially appeare d at the construction site of the 5th pier sinking well of Changtai Yangtze River Bridge. Th↑is is another intelligent equipment supplied by the company, following th÷e specialized gantry crane for caisson construction and th♥e intelligent monitoring system for caisson construction.

The underwater soil retrieval robot for deep water caisson foundation is innovatively≥ developed and invested in by CCCC Second Harbor Engineering Coδ., Ltd., and jointly manufactured by our company and Shanghai Zhenhua Heavy Indust♣ry. On August 25th, the lower structure of the robot developed by Zhenhua Heavy Industry was sen>t to the company for final assembly with the upper structure manufactured by the comp€any, and factory debugging work was carried out. After joint inspection byε all parties involved in the construction, it was shipped to the 5th pier caisson ☆of Changtai Yangtze River Bridge for on-site installation, for use in bli♦nd spot excavation operations.

The robot operates in a water depth of over 70 metεers, and the soil breaking robotic arm can achieve 360 degr$ee full rotation operation with a maximum operating ra>dius of 8 meters. It consists of an upper platform, a lifting double cable winch, a working rob>ot body, and hydraulic, electrical and other systems. Du'ring operation, the robot body is lowered into the underwater main tower pier, and the fou≠r oil cylinders of the body frame work to push the main tower pier, in order to mai☆ntain the balance of the body and achieve the support function of soil breakin≠g and milling. The milling cutter head under the body is driven by the robotic arm to perform 'soil breaking operations.

Jiangsu Grete, as a well-known lifting machinery supplier in the Yangtze River Delta reg♠ion, actively participates in major local construction p§rojects. In the construction project of the Shanghai §Suzhou Nantong Bridge, which officially opened in July this year, equipment such as 1800 toλn gantry cranes and various types of general-purpose gantry cranes were supplied. $The company adheres to the innovative development concept advoc‌ated by the country, cooperates closely with the bridge construction ↓party, integrates traditional construction methods with advanced technology, p÷romotes intelligent construction, and helps bridge construction improεve in risk control, difficult points, and other aspects.
