According to the different power heads equipped, high-lift/long boom drilling rigs can be divided into two categories: top-hammer high-lift drilling rigs and DTH high-lift drilling rigs.
Top Hammer High-Reach Drilling Rigs:
Typically used with drill rods or self-drilling anchors.
Drill hole diameter: Φ51-Φ115mm.
Drilling depth generally does not exceed 20 meters.
Advantages: Fast drilling speed and low energy consumption.
Down-the-Hole (DTH) High-Reach Drilling Rigs:
Typically used with DTH drilling tools.
Drill hole diameter: Φ90-Φ180mm.
Drilling depth can exceed 30 meters.
Advantages: Capable of larger diameter and deeper holes.
Product Advantages
High construction efficiency
Without moving the equipment after one-time positioning, the high-lift drilling rig can perform drilling operations within a height range of tens of meters. The maximum single-rod drilling depth can reach about 10 meters, which reduces auxiliary time such as rod connecting, rod changing, and drilling rig shifting, greatly improving drilling efficiency.
Diversified construction methods
The high-lift drilling rig can be equipped with different power heads as needed and connected with various drilling tools for construction, such as DTH drilling, casing drilling, auger drilling, self-drilling anchor rod drilling, etc. Equipped with a 90° two-way deflection device, the drill arm can rotate left and right by 90° for side drilling, which is not limited by the narrow working surface of the platform and has good adaptability to working conditions.
Accurate drilling angle
The high-lift drilling rig is equipped with a central rotating disc brake with a hydraulic brake, which can effectively prevent the drill arm from deflecting during hole formation. A high-definition camera is installed on the drill mast, and an angle gauge is configured in the cab to ensure accurate drilling angle. At the same time, a length counter is equipped, so there is no need to estimate the drilling depth.
Low comprehensive cost
There is no need to build auxiliary construction platforms such as scaffolding before construction with the high-lift drilling rig, which simplifies the construction process, shortens the construction period, and reduces investment costs.
Environmental protection
The high-lift drilling rig has a built-in integrated air compressor with large air volume for slag discharge and fast drilling speed. In addition, it can be equipped with water wet dust removal, which can effectively reduce dust emissions and achieve environmental protection.
