Features and Advantages

Gookma rotary drilling rig includes many core technologies, it leads the trend of medium and small piling machine.

1. High Speed Mud Dumping

The high speed mud dumping function is realized through the unique design of the power head.

With both strong strength and high speed, it obtains many advantages in all working conditions, working efficiency is 20% higher than other products.

High Speed Mud Dumping

2. Visual Human-machine Interface

With the visual human-machine interface, he information or working conditions are visual, to make the operation more direct and easy.

The core parts have time-delay settings, makes the operation more smoothly, reduce parts shocking, and prolong life of the machine.

3. Convenient Maintenance and Repairing

Electromechanical design, makes the machine is of easy maintenance and repairing, water proof and safe, and high reliability.

Visual Human-machine Interface

4. Advanced Design

The machine is developed by advanced designing software and force analysis software, it can display more directly the stress analysis area of the product structure, so as to optimize the product structure.

5. Safety Performance

Synchronous operation function of return rope, prevent from laying of drilling tools accidentally. The drill rod equips with anti punching device, which has posterior image function.

Advanced Design

6. Agile Mobility
