On July 02, 2021, Five trenchless drilling rigs have been produced and entered the offline inspection and acceptance. The customer sent a Chinese representative to visit our factory for acceptance. After the customer representatives entered the workshop, they were first shocked by the clean, tidy, large and standard workshop in front of them. Secondly, under the leadership of our engineers, carefully check and accept. Finally, the customer representative took a group photo with the machine. And we are very satisfied with our enthusiastic service and product quality.
