Hydraulic rock drill is a new generation of Zaoyanjixie products. The early 1960s, the German Krupp company developed a practical hydraulic crusher, it is first used for urban construction projects; 1970 French the Montabert Company First successfully developed the worlds first practical hydraulic rock drill, and soon put into mass production, drill rig for sale and promote the use; followed by Sweden, Germany, the United States, Finland, Japan and other countries has been developed and the various types of hydraulic rock drill or hydraulic crusher market. Compared to traditional dth drill rigpneumatic impact mechanical,water well rigs suppliers hydraulic impact machine has low energy consumption, high efficiency, low environmental pollution, easy to operate, easy to realize the advantages of automation in the water well drilling rigs for sale
