Our company's first set of blasting-free rock construction products came out in 2011 under the painstaking research and development of the open source intelligent technology team. A series of products have been launched one after another, and they have quickly won praise from users because of their environmental protection, high efficiency, and low maintenance costs. The innovative rock-breaking arm technology has obtained a number of national patent certificates. The products are sold throughout the country and exported to Russia, Pakistan, Laos and other regions. They are widely used in road construction, housing construction, railway construction, mining, permafrost stripping, etc. construction works.
