Rock drilling rig Used deep rock well drilling rig down-the-hole drill Blast hole piling
Rock drilling rig Used deep rock well drilling rig down-the-hole drill Blast hole piling
It is used in blast pits of open-pit mine quarries and various steps to excavate medium soft rock and medium hard rock layers to meet productivity needs.
Aperture range: 90-130mm
Stronger drilling ability and higher quality of hole formation.
ZEGA D440 brings the following benefits
Charges control blast effect
Through parallel and pre-split blasting, speed up the peeling speed.
By increasing the slope angle, the excavation of waste rock is reduced.
Flexibility is significantly better than traditional open pit and quarry rigs.
Excellent return on investment
The D440 drill rig has a working wind pressure of 20 bars, a drill pipe length of 3.5 m, and two diameter drill pipes to choose from, which can be used to drill foot holes.
High efficiency, energy saving, environmental protection and safety
n Two-stage compression air compressor with energy efficiency ratio is used to achieve high wind pressure rock drilling. It has excellent fuel economy performance, more energy saving and more environmentally friendly.
n High-torque swivel head to overcome the stuck phenomenon in most rock formations.
n Two-stage dry dust removal system to meet environmental protection requirements.
n Fully enclosed air-conditioned cab with good sight and comfortable and safe operation.
n New-type propulsion beam with excellent guidance and stability, realizing high-precision drilling.
Flexibility and mobility
D440 drilling rig has excellent walking performance, and transfers quickly and safely in the work place. Because of the balanced weight distribution, low center of gravity, suitable chassis ground clearance, and heavy-duty track frames with a swing angle of ± 10 °, the off-road capability is outstanding. It can also perform vertical or various angle drilling on sloping slopes.
More convenient maintenance
Like other drilling rigs of Chigo, the D440 was designed with the convenience of maintenance in mind. The maintenance space in the cabin is spacious, and all maintenance points are within easy reach. Marking rings are provided on both ends of the oil pipe and cable for easier maintenance.
The straighter the slope, the better the economy
Using ZEGA D440 for down-hole pre-split drilling can make the steps higher and narrower. This makes the slope steeper and reduces the amount of excavated waste rock. This has the advantage of reducing the rate of depletion, which means higher production and better overall mine economics.
