HAMAC boom pump has 5 models for your option. 30m, 38m, 48m, 56m and 63m. 38m is the hot model. This client visited China in September, 2019. Because of strict schedule, he couldn't visit our factory in person. We took a video call to show him our factory. He is impressed at our factory scale, equipment configuration and service. In May, 2020, we signed the contract. We felt very honored to supply equipment for such a large construction company and we are confident that we will have more cooperation in the future.
