Recently, Jiangsu Taixin Machinery received a letter of thanks from the 11th Engineering Bureau of China Water Resources and Hydropower for the project in Zambia. The customer purchased 1 KR125A rotary drilling rig in 2015 and 2017, respectively, for the KK330 power transmission project ( Kariba-Kaifu Gorge West Switching Station) and CLC132 transmission and transformation project (Chipata-Lendaz-Chama) transmission tower foundation construction.Both of these projects are constructed in Zambia, and have the following construction difficulties: 1. The construction of transmission lines abroad is very long, and the construction transition requires convenient transportation as a whole; 2. The stratum constructed along the way is relatively complicated, including sand, pebbles, and boulders. , Strongly weathered stratum, etc.; 3. With good climbing performance, there are hilly areas along the way.Taixin Machinery’s KR125A rotary drilling rig has a weight of 35 tons, a construction diameter range of 400-1500mm, and a construction height of 15 meters. Slope performance.The KR125A rotary drilling rig performs well in construction, with high reliability and construction efficiency. At the same time, Taixin’s experienced special service personnel train construction technical personnel for customers, train repair and maintenance knowledge hand-in-hand, and introduce mature construction techniques. It provides a solid guarantee for the smooth completion of the construction tasks of the project, and at the same time has cultivated a large number of construction technical personnel for China Power Construction, and has accumulated rich construction experience.
