As China-Africa cooperation continues to progress and deepen, cooperation stories are continuously unfolding on the continent of Africa, and Chinese engineering machinery is also showcasing its capabilities in African infrastructure projects. Recently, on the Rosso Bridge project in West Africa, ZOOMLION's full-rotary drilling rig efficiently and reliably completed the piling task, helping the construction of the bridge foundation to steadily advance. The high-quality products and services provided by ZOOMLION have received unanimous praise.

It is reported that the Rosso Bridge, located on the Senegal River at the border between Senegal and Mauritania, is the first large-scale project jointly constructed by the two countries. Once completed, the Bridge will become an important hub of transnational trade trunk lines in Africa, greatly saving cross-border travel time between the two countries and facilitating personnel and material exchanges.

To safeguard the local environment, the Owner has forbidden the use of chemical sludge for wall protection. Due to the sandy soil composition, the rotary drilling rig cannot be used due to the risk of collapse. Originally, the client intended to drill holes with disposable casing and vibrating hammer; however, this approach proved excessively costly. After a thorough consideration, the full-rotary casing drilling method was adopted with reusable casing to reduce costs, and the reputable ZOOMLION's full-rotary drilling rig was selected for the operation.

Since the mobilization of equipment in February this year, the ZOOMLION service team has rapidly completed the training of local construction personnel to ensure that African workers can skillfully operate the full-rotary drilling rig. The implementation of European standards that prohibit the use of chemical sludge in Africa necessitates the employment of full-casing technology. The ZRT260H full-rotary drilling rig utilized on this occasion sets a benchmark pile as requested by the client, with a casing depth of 55 meters and pile depth of 52 meters. With a crawler crane, the rig excavates soil swiftly," remarked Tong Bing, a resident service engineer of ZOOMLION in Africa. "The client commented the machine's robustness and stability, and the stable construction and achieved casing depth met their expectations."
