Features
1. Energy conservation : the product due to the drilling operations of the hydraulic drive of the hydraulic system , the configuration of the hydraulic rock drill drilling capacity equivalent to six YT28 pneumatic rock drill , drive power 55KW , YT28 type pneumatic rock drill driver power 150KW pneumatic drilling power loss , only 1/3. products actually used hydraulic proportional control system with better energy efficiency .
2.Drilling machinery and accessories and low cost : about 10 times the hydraulic pressure pneumatic pressure . Therefore , in the same impact velocity , hydraulic rock drill piston of smaller areas of impact piston area close to the solder tail area , stress transmission loss is small . Force uniform, high life expectancy , less failure , so the cost of a pneumatic rock drill can be reduced by 30%
