full hydrailic, rubber crawler type HFDP-20 trenchless horizontal directional drilling

 

1. General Description

The HFDP-20 is a full Hydraulic Directional Drilling Rig self-propelled with rubber crawler belts. with advanced and compact structure, high efficiency, low oil temperature; Main hydraulic components, motor and mud pump all selected and adopted from domestic famous-brand products as auxiliary equipments; Equipped with durable rubber belts of crawlers, the rig is suitable for moving in the city. And the rig could get on and off standard trailer on its own and it is quick for transportation and allocation. with movable mast, the rig is guaranteed to drill within the full angle scope. It is in good stability with graceful structure.

 

1) with low emission diesel engine, it is suitable for performance in city; Direct fuel injection requires not preheat in winter.
2) The chassis and mast are high in rigidity and intensity, they are durable and reliable.
3)Equipped with hydraulic outriggers, the rig could be adjusted to balance and stability with convenience and easiness.
4) The mud pump is driven hydraulically with four-speed mechanical gear shift/stepless speed change. with controllable wide flow range, the displacement could be adjusted flexibly according to different geological conditions and performance techniques.
5)Equipped individually of mud processing unit, adopting injection and recirculation storage procession method, the efficiency will be increased and the intensity of labor will be decreased.
6)with the rod, 60mm in diameter and 3000mm in length, the drilling tools are complete in matching accessories and could be produced in accordance with the requirement of clients unusually.
