Horizontal Directional Drilling Machine Characteristics:

1. Replace cooling and breast wall slurry with compressed air and a small amount of additive, which is environment friendly    and cost saving.

2. Drilling tools add the top impact while rotating and pushing and resolves the construction problem of cobbles and gravels which is considered to be a forbidden zone.

3. All dynamic, hydraulic and electric components, drilling tools and instruments as well as other key parts and details adopt world famous brands which are high effective and reliable.  

4. Dry type, wet type and dry-wet type drilling modes can be adopted; dry type drilling is used for pipe line construction below Ф400mm and the soil quality can be rock, cobbles and gravels, backfilling and other kinds of clay; wet type drilling can be used for pipe line construction below Ф700mm and the soil can be any kind of soil except rock.

5. Full load sensitive control makes operation with high efficiency and low consumption.

6. The main engine power setting is divided, occupies smaller floor space and is fitter for construction in narrow zones.

7. Wired remote control meets the demand of specific environment.

8. The main lubrication points of Lincoln central lubrication system can keep lubricating maintenance periodically.

9. Comings QSL9 supercharged, inter-cooling and electric control engine can work in regular state in regions with an altitude of 4500m. Cooperating with Zoomlion special control system, it is energy-saving.

10. Supercharging hydraulic tank can improve the absorbing oil pressure and lifetime of the hydraulic pump.

11. Load feed-back and load sensitive hydraulic system can adjust cubic capacity of pumps automatically according to the capacity required and the control accuracy does not decrease with change of load.

12. Hydraulic effective cooling system can make sure that the machine works with high load in high temperature environment of high thermal zones.
