Product Description Information
Small stature, high energy. Used for blasting and drilling of soft and medium hard rocks in open-pit mining quarries and various bench excavations to meet productivity requirements.
Stronger drilling ability and higher drilling quality
On the basis of mature technology, Zhigao Mining continuously improves the drilling rig production capacity and operational adaptability. The ZEGA D440 integrated drilling rig is perfect in terms of application flexibility and reliability, with higher production capacity, stronger adaptability, and better drilling quality< Br data filtered="filtered"/>
It is possible to rely on a drilling rig for production drilling, accelerate stripping speed through combined and pre split drilling, and control dilution rate. With its lighter weight and compact size, the D440 is very convenient for transfer between construction sites and steps. Due to its excellent flexibility and powerful operational capabilities, the D440 drilling rig is widely suitable for various drilling applications, such as production blasting holes, pre-splitting holes, shock absorption holes, slope relief holes, and ultra deep hole operations in open-pit quarries and mines.
The ZEGA D440 integrated drilling rig brings the following benefits
Accurate straight holes can control the blasting effect

Accelerate stripping speed through combination and pre splitting blasting

Reduce excavation of waste rocks by increasing the slope angle

The flexibility is greatly superior to traditional open-pit and quarry drilling rigs;
Product Features
1. Heavy duty motor chain propulsion beam, stable and reliable

2. Box shaped boom, sturdy and flexible

3. Full view air-conditioned cab that meets the requirements of anti falling FOPS and anti rolling ROPS, noise and vibration resistant

4. Fully enclosed structure with gas spring protective door for easy maintenance

5. Disc type rod changing system with strong ability to drill deep holes< Br data filtered="filtered"/>
6. Rotary head suitable for 3.5/4 inch DTH hammers, torque up to 2800 Nm;
Excellent return on investment
The D440 drilling rig has a working air pressure of 20bar, a drill pipe length of 3.5m, and two diameters of drill pipes to choose from, which can be used to drill foot holes. The drilling speed is significantly faster than other products of the same type.
