Product Description Information
A small size, great power. Suitable for blasting and drilling of soft and medium-hard rocks in open-pit mining quarries and various bench excavation sites, meeting the productivity requirements.
Stronger drilling capabilities and higher hole formation quality
Based on mature technology, Zhigao Excavation has continuously enhanced the drilling machine's production capacity and operational adaptability.
ZEGA D440 Integrated Drilling Machine has been perfected in terms of application flexibility and reliability, with higher production capacity, stronger adaptability, and better hole formation quality.
A single drilling rig can be relied upon for production drilling. By using parallel sections and pre-split drilling, the stripping speed can be accelerated, and the dilution rate can be controlled. With its lighter weight and compact size, the D440 is very convenient for transfer between construction sites and between steps. Due to its excellent flexibility and powerful operational capabilities, the D440 drilling rig is widely adaptable for various drilling applications, such as production blasting holes, pre-split holes, shock absorption holes, slope relief holes, and ultra-deep hole operations in open-pit quarries and mines.
The D440 Integrated Drilling Rig Offers the Following Benefits
Precise straight holes can control the blasting effect
By increasing the slope angle, waste rock excavation can be reduced
2. Box-type boom, sturdy and flexible
3. Full-view air-conditioned cab with anti-noise and shockproof features, meeting FOPS and ROPS requirements for rockfall prevention and rollover protection
4. Fully enclosed body structure, air spring protective door, convenient for maintenance and servicing
5. Disc-type swivel system, strong in drilling deep holes
6. The rotary head suitable for 3.5/4-inch plunge drills, with a torque of up to 2800 Nm.
Excellent Return on Investment
The working wind pressure of the D440 drilling rig reaches 20 bar, the drill pipe length is 3.5 meters, and there are two diameters of drill pipes available for selection, which can be used for bottom foot holes. The drilling speed is significantly faster than other similar products of the same type.
High efficiency, energy saving, environmental protection, and safety
It adopts a two-stage compression air compressor with excellent energy efficiency ratio. It can achieve high-pressure rock drilling, has excellent fuel economy performance, and is more energy-efficient and environmentally friendly.
The large-torque rotary head can overcome the stuck drill problems in most rock formations.
Two-stage dry dust removal system, meeting environmental protection requirements.
Fully enclosed air-conditioned cab, with excellent visibility and comfortable, safe operation.
The new type of driving beam has excellent guiding and stability, enabling high-precision drilling.
Flexibility and Mobility
The D440 drilling rig has excellent traveling performance, allowing for quick and safe transfer within the working area. This is due to the balanced weight distribution, low center of gravity, appropriate chassis ground clearance, and the +/− characteristic of the heavy-duty crawler frame. 10° With its swinging angle, it has excellent off-road capabilities. It can also perform vertical or various angle drilling tasks on inclined slopes very well.
More Convenient Maintenance
Like other drilling machines of Zhigao, the D440 was designed with the consideration of ease of maintenance. The maintenance space inside the machine compartment is spacious, and all maintenance points are within easy reach. Marking rings are provided at both ends of the oil pipes and cables, making maintenance even more convenient.
The steeper the slope, the better the economic performance.
By using ZEGAD440 for deep-hole pre-splitting drilling, the steps can be made taller and narrower. This results in a steeper slope, reducing the amount of waste rock excavation. The benefits are a lower depletion rate, meaning higher production and better overall economic performance of the mine.
