1. The XY-44A core drilling rig is fabricated with reasonable speed range, 8 speed levels, and large torque at low speed which can be up to 8000N.m. It is not only suitable for alloy and diamond core drilling, but also applied for engineering geological investigation, hydrological well drilling, and the construction of pile foundation engineering.
2. The spindle bore diameter is as large as 93mm. Featuring biaxial cylinder hydraulic feeding, long stroke of up to 600mm, and strong technological adaptability, the spindle of the product is very fit for large diameter drilling rod wireline coring (upper part coring) drilling, and is conducive to the enhancement of the drilling efficiency and the reduction of the drilling accident in the hole.
3. The core drilling rig has large drilling capacity. The rated drilling depth of the wireline coring drilling rod with the diameter of 71mm can be up to 1000m.
4. The product is also highlighted by good dismountability and light weight with the net weight of only 2300kg. The main body of the machine can be dismantled into 10 major parts. The maximum detachable part weighs 300kg. Based on that, the machine is particularly applicable for working in the mountain area.
5. The hydraulic chuck of the core drilling rig uses one-way oil supply. It has large chucking power and chucks the drilling rod stably.
6. The product is configured with the hydromatic brake. It is capable of deep well drilling with stable and safe process for the drilling tool into the well.
7. The machine adopts single gear oil pump to implement oil supply. The installation is simple and it is very convenient to use the device. Moreover, the power consumption is low. The hydraulic system works stably with low oil temperature. In addition, the hand-operated oil pump is available. When the power machine fails to work, the operator can use the hand-operated oil pump to take the drilling tools out of the hole.
8. The core drilling rig has compact structure and reasonable layout with all the parts exposed to the outside and no overlapping with each other. The maintenance and repair work can be conducted easily.
9. The machine has low center of gravity, long backward travel of up to 460mm, and good high speed drilling stability. It can be fixed firmly.
10. The product is also fitted with shockproof instrument which has long service lifetime and facilitates mastering the condition in the hole. Designed with not too many control handles, it is flexible and reliable to operate.
11. The core drilling rig has high degree of universal property. Its 60% parts can be applicable for the XY-4 product. As to the XY-42 product, the proportion of the interchangeable parts of the product is as high as 75%.
