120T DFHD-120 underground pipeline laying rig HDD machine with 1200KN Pulling Force

1. Introduction

DFHD-120 trenchless horizontal directional drilling rig is a full Hydraulic drilling rig mounted

on self-propelled rubber crawler. 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.

2.Advantages

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.
