Product Description

1.Main Technique Parameters:

2. Different view of GT450-L  HDD drilling machine 

 

 

 

 

3.The Main Configuration:

1),Engine: C series which is specialized for engineering machinery, made by Dongfeng Cummins ( 194Kw/2200rpm)

 

2),Hydraulic Oil Pump:

     (1),Originally imported pump made by Am. Sauer-Danfoss for rotary and push & pull. 

     (2),adopts the international brand gear pump for clamp and other assistant mechanical system;

 

3),Motor and Reducer

- Hydraulic motor: adopts 3 sets rexroth for push & pull and rotary;

- Planetary reducer: 3 sets Italy or Germany Brands for rotate and push & pull;

 

4),Mud Pump:450L/min ;

 

5),Transfer case: made in German improves the speed of push & pull and rotary;

6)Rack and pinion: made by high wear-resisting, high impact alloy steel;

7),Electric parts:made in Schneider;

8),Caterpillar:Self-made steel caterpillar with rubber-board, which can bear high load and easy walking;

9),Handle:Am. Sauer Danfoss electric control handle, which is simple and reliable, sensitive;

10),Hydraulic valve:Rexroth type valves, Italy SAM flush valve;

11),Mechanical arm: Semi-automatic with self- lock big range rotate mechanism; (optional components)

12),Crane: 2 ton crane reduces the work strength.(optional components)

  

   4.Advantages of GT450-L

 

• The rotary and push and pull adopts closedcircuit, which can low down the temperature and reduce the near. Other assistant mechanical adopts open circuit driven by high pressure gear pump.
• The Girder adopts fourconnecting rod to increasing the range of the entry angle. Meanwhile, it makes sure of the caterpillar landed on the ground when rig in big angle, which improves the safety;
• Balance of the clamp makes sure of the concentricity and protection of the rod thread;
• Cabin can automatically move up and rotate, which improves the view;
• Transfer case made in German improves the Rotary and Push & Pull Speed;
• The arrangements of oil pipes are reasonable and clear, the structure of the chassis is enhanced;
• Safe wire -controlled walking system;
• The floatable of the main axle can protect the rod thread and reduce the stress;
• Comparing to the traditional hydraulic system, the advanced hydraulic system improve15-20% of the work efficiency, reduces 50% heat lost and saves 15-20% energy.;
• Cooling system is equipped on the power head, which can protect the speed reducers and motors.
• Unique design of the mechanical hand reduce the workforce and improve the work efficiency.
