High Return Drilling Rig Equipment , Hydraulic Raise Boring Drills 400m Max Depth
Function Characteristics
Effectiveness and precision reduce wear and thus additionally prolong service life.
The electric motors achieve significantly higher efficiency compared to hydraulically powered machines. Variable speed and torque control also allows the precise transmission of power to the drill string. This increases the efficiency of the drilling operation without risking overloading of the individual drill pipes.
High-pressure hydraulic system with constant power control, load sensitivity and full-scale electromagnetic control. The electric power takes on all the functions of the field operation, and the diesel power is responsible for the walking function.
Our raise boring machine has high maximum torque and thrust forces. So, it is possible to full capacity drilling due to high maximum torque and thrust forces.
