Product description information
Historical Story > https://www.lishila.com/
A perfect combination of low cost and high production capacity
Simple design, intuitive control system, more reliable, easier to maintain.
Greater production capacity, equipped with 6-meter drill pipes, with a wide range of hole diameters.
The segment operation is even more efficient and energy-saving.
Product Features
1. Push Rod
Hydraulic cylinder with steel wire rope for pushing, with high control accuracy of pushing force, enabling high-precision rock drilling.
It can drill holes at various angles and horizontal bottom foot holes.
Composite material self-lubricating bearings require no maintenance and eliminate the hassle of regular lubrication.
2. Rod Changing Device
The disc automatic rod changer enables you to freely select the drill pipe, thereby extending the service life of the drilling equipment.
The patented floating pipe holder design eliminates the concentrated points of pipe deformation, thereby extending the service life.
3. Dust Removal Device
A two-stage dry dust removal system with a large dust removal and filtration area, capable of automatically and continuously self-cleaning for dust removal.
The dust removal filter element array can be easily disassembled, and the maintenance efficiency is high.
The dust collection cover can slide up and down. It allows for clear observation of the opening situation and enables control of the opening.
4. Power Rotating Head
The cycloidal hydraulic dual-motor rotating head has high torque and excellent reliability.
5. The Upper Arm
Strengthen the box-shaped upper arm, which is highly resistant to tension, compression, bending, torsion and shear forces. The structure is simple, maintenance is convenient, and the positioning is accurate.
6. Diesel Engine
Power system fuel-saving devices and automatic preheating devices, suitable for various demanding working conditions.
An additional high-altitude package can be installed to enable applications for high-altitude environments.
7. Air Compressor
A screw-type two-stage compression high-pressure air compressor with excellent energy efficiency ratio. It can achieve high-pressure rock drilling.
