Three-arm drilling jumbo

Three-arm drilling jumbo

It can be divided into two types: computer-controlled and hydraulic-controlled, it has the characteristics of generator four-wheel driving,  plastic wheel walking, strong force, flexible moving; The power is provided by electric generator, the three working arms are separately drived by relative electric motor pumps. It has the advantages of environment friendly, operation convenient and position accurate. It can achieve the function of separate control and simultaneous working for three arms; The digitalized full smart controlling system has the function of automatic positioning, as well as automatic adjustment for arm posture. It can make drilling automatically by leading the pre-programmed drilling diagram into jumbo control system.
