THD-70 HORIZONTAL DIRECTIONAL DRILLING MACHINE
THD-70 HORIZONTAL DIRECTIONAL DRILLING MACHINE
Product Description
The THD-70 Horizontal Directional Drilling Machine adopts full hydraulic drive and dual speed track walking; Dual low-speed motor drive power head dual speed drilling, advanced and simple structure; Gear and rack transmission system, smooth and reliable movement;The cab is equipped with air conditioning, providing a comfortable operating environment for the operator.
Our company produces multi-series and multi-varieties of horizontal directional drilling rigs with high reliability, simple structure, powerful functions and superior performance. It is a man-machine integrated pipeline construction equipment continuously improved by integrating the theory and practice of outstanding designers and constructors for more than 20 years with the current development of artificial intelligence and automation.
1. The drilling rig has a beautiful appearance, and the whole machine is fully hydraulic driven. The walking adopts wired remote control mode, and the main supporting components are selected from well-known domestic and foreign brands.
2. The characteristics of low emissions and low noise of branded diesel engines, combined with internationally leading control technologies, are not only more suitable for urban construction, but also minimize the power consumption of drilling rigs under no-load conditions.
3. The power head rotation is driven by a dual low-speed high torque motor and is equipped with a two speed stepless speed regulation function.
4. The power head push-pull is driven by a four motor gearbox and a rack and pinion transmission, with good stability.
5. It can be equipped with wireless and wired guidance devices, in terms of usage.
6. The mud pump is hydraulic driven and mechanically variable in speed, allowing for flexible adjustment of pressure and pump volume.
7. The supporting drilling tools are complete and adopted φ one hundred and two × 5000mm drill pipe, randomly equipped with a 2T crane.
