GD600-L Horizontal Directional Drilling Machine Technique Proposal

I.          Main Technique Parameters:

Rig Weight:                   22T	Size (L×W×H mm):        10300×2500×2800
Max. Push & Pull Force:         650/1300KN	Max. Torque:             26960N·m
Max. Push & Pull Speed:         32m/min	Max. Rotary Speed:        98 r/min
Rig Walking Speed:             3/5.6Km/h	Max. Pressure on Mud Pump: 10Mpa
Drill Entry Angle:               10～18°	Max. Climbing Gradient:    20°
Max. Diam. of Expanding Aperture: 1300mm(depends on the earth condition)	Max. Drilling Length:       900 m(depends on the earth condition)

II.       MainConfiguration:

1.       3500×550 walking caterpillar;

2.       Engineering machinery Engine(239KW) made by Dongfeng Cummins;

3.       Closed hydraulic system- variable piston pump made by Am. Sauer, hydraulic motor and wash valve made by SAM(Italy) or Am. Sauer;

4.       Planetary reducer made by DANAMIC (Italy) or KPM (Germany);

5.       Large module alloy steel rack and pinion;

6.       Electricity proportional control system made by Am. Sauer;

7.       Wire-controlled walking system;

8.       Mechanized rod-install system;

9.       2T crane.

III.     Main Performance Characteristics:

1.       Hydraulic system: closed push-pull, rotary and walking system, electricity proportional control;

2.       Clamp separately floating;

3.       Push-pull transmitted by rack and pinion;

4.       Main axle is floating that is preferable for the rod thread;

5.       Electricity controlled handle made by Am. Sauer, the circuit layout is plain, but reliable and sensitive;

6.       Safe wire-control walking system;

7.       Mechanic rod-install system, which is efficient but requires less manual work.
