Product Description

Key Features & Advantages

Versatile Rotation Speed: Features 8 rotation speed series with an appropriate range, providing low speed with high torque. Ideal for alloy core drilling, diamond core drilling, engineering geological exploration, water wells, and foundation hole drilling.

Large Spindle Diameter: Equipped with a large spindle inner diameter (Ф93mm), double hydraulic feeding cylinder, and a long stroke up to 600mm. Highly adaptable for wire-line coring of large diameter drill pipes, improving drilling efficiency and reducing hole accidents.

Deep Drilling Capacity: Exhibits powerful drilling capabilities, reaching a maximum rated drilling depth of 1000 meters using a Ф71mm wire-line drill rod.

Lightweight & Modular: Net weight of 2300 kg. The main machine can be disassembled into 10 components for convenient transport, assembly, and disassembly, making it highly flexible for mountainous terrains.

Hydraulic Chuck System: Adopts one-way oil supply, spring clamping, and hydraulic release. Provides strong, stable chuck clamping force for safe operations.

Deep Hole Safety Brake: Equipped with a robust water brake, ensuring smooth and safe operations during deep hole drilling.

Stable Hydraulic System: Utilizes a single gear oil pump for simple installation, ease of use, low power consumption, low oil system temperature, and stable execution. Includes a backup manual oil pump to safely retrieve drilling tools if the engine fails.

Compact & Low Maintenance: Rational overall layout makes maintenance and repair highly straightforward while maintaining a compact operational footprint.

Excellent Stability: Designed with a low center of gravity and a long skid stroke, establishing rigid fixation for outstanding stability during high-speed operations.

Intelligent Monitoring: Equipped with a long-life, shockproof instrument panel to grasp real-time downhole conditions easily. Uses fewer control levers for responsive and reliable operation.

Frequently Asked Questions

What is the maximum drilling depth of this rig?

The maximum drilling depth depends on the drilling configuration. For core drilling using a Ф55.5mm rod, it can reach up to 1400 meters. For Ф71mm wire-line drill rods, it has a rated depth capacity of 1000 meters.

What are the advantages of the spindle design?

The spindle features a large inner diameter of Ф93mm and a double hydraulic cylinder for feeding, paired with a long stroke of 600mm. This is highly suitable for large-diameter wire-line coring, increasing overall drilling efficiency and minimizing downhole accidents.

Is this drilling rig portable enough for mountain work?

Yes. The main machine has a net weight of 2300 kg and can be easily disassembled into 10 components. This modular design makes transportation, handling, and assembly convenient in challenging mountain terrains.

What safety measures are built into this drilling rig?

The rig is equipped with an integrated water brake to ensure smooth and safe performance during deep hole drilling. Additionally, it features a shockproof instrument panel to accurately monitor the condition inside the hole.

What happens to the drilling tools if the engine stops working?

The hydraulic system features a single gear oil pump design equipped with a manual backup oil pump. Even if the primary engine fails to run, operators can use the manual oil pump to retrieve the drilling tools safely.

What power options are available for this rig?

The rig can be powered by either a diesel engine (model R4105ZG53, rated at 56KW at 1500r/min) or an electrical motor (model Y225S-4, rated at 37KW at 1480r/min), depending on your job site requirements.
