Two complete sets of water well drilling rig which we produced for China Railway Resource Group Co., Ltd on Congo (gold) drilling project were finished at the end of June. Our company sent professional technical personnels to Congo for helping them installing and commissioning. We helped them drill the first big diameter hole successfully. Our customers were very satisfied for the quality of our equipments and service, and gave us high praise.
