Top Brand Sr155 Small Hydraulic Mining Core Drilling Rig Rotary Drilling Rig Machine
The rotary drilling rigs are of wide range of uses, and currently they have won the universal agreements in the pile market with their distinctive drilling way. They have been fully applied home and abroad in key construction projects like port, pier, elevated highway, civil engineering and high buildings.
Feature:
5-level anti-vibration technology absorbs drilling vibrational frequency all- directionally to guarantee high stability;
The special lubricating system makes sure that it can work in high-temperature environment. Rotary drive is available in three drilling modes-standard, low speed and big torque or high speed and small torque; spin-off is optional;
The removable key of rotary drive and symmetry structure design double its service life;
The main winch has highlights of touch-bottom protection, priority control and fast line speed;
Crowd cylinder has two operation modes---normal lifting and fast lifting to improve push efficiency;
Mast features automatic erecting, lying and vertical adjustment to ensure the accuracy requirements in construction;
Balance control system of the whole machine is available.
