Product Description

Hydraulic Underground Diamond Core Drilling Rig with High Drilling Efficiency

 

I. Drilling Capacity

 

Drill Rod	Downward Hole (m)	Horizontal Hole (m)	Upward Hole (m)
A	1,000	650	750
B	750	470	650
N	600	370	370
H	350	210	210

 

 

II. Major Components

 

.1 Control Table

 

Feeding, rotation, reversing, rod lifting, clamp jaw tightening and releasing,winch winding and releasing all controlled through the handles on the control table.

Simple in operation but powerful in control.

2 Power Unit

The power unit is mounted on a wheeled frame independent to the drill body. It is composed of electric motors, hydraulic pumps, hydraulic cylinder, hydraulic oil tank, and electric control box.

Electromotor model	BM2-250M-4-B35
Power	55Kw
Electromotor RPM	1,480rpm

 

 3 Rotator

Hydraulic chuck with interchangeable jaws in the power head allows adaptation to different size rods. The spindle speed can be automatically adjusted by hydraulic motor.

Max. Torque	1,030Nm
Max. Rotation speed	1,145rpm
Feeding stroke	1,800mm
Max. Spindle dia.	97mm
Max. Pulling force	65Kn
Max. Feeding force	65Kn

 

4 Hydraulic System

Pressure	26MPa
Cooling	Water cooled

 

5 Drill Mast

Length	3.3-5.8m
Drilling angle	-90°~+90°
Slid length	1.1m

 

6 Hydraulic Rod Holder

The clamping action of the clamp jaws in the hydraulic rod holder is synchronized with the hydraulic chuck in the power head. The tightening of the clamp jaws is mechanically operated, while the releasing of the clamp jaws are hydraulic controlled. This ensures that when there is un-expected stoppage in the drilling operation, the drill rod can still be strongly held by the rod holder, so as to ensure the safety in the drilling operation.

Drill rod

A, B, N, H
