Details:
XY-44A Core Drilling Rig

XY-44A is a core drilling rig for middle and deep hole. It applies to all kinds of core drilling and engineering geological reconnaissance. Also the machine is widely used on areas such as road、railway and port construction, water resources and hydropower and architecture. The structure of the machine is reasonable、the weight is light and the capability is powerful. The XY-44A is also with a high degree of standardization and generalization.
 
Features:
1): the drilling rig adopts vehicle transmission case and clutch, with simple structure and rational layout. It runs stably, with lower noise and high transmission efficiency, and is easy to dismount and assemble.
2): it has a rational speed range, more speed grades, big low speed torque and a wide application range
3): the drilling rig is equipped with a water brake device, which is convenient for deep-hole drilling and is safe and smooth to perform drill tool lowering
4): two gear reverse speeds, easy for dealing with the in hole accident
5): large power
6): advanced structure and rational layout, convenient for maintenance and serving.
7): the drill rig is small in volume, light in weight, and easy to be disassembled and moved
8): has long feeding travel of vertical shaft, which is beneficial to improve drilling efficiency and reduce the probabilities of bit-jam and bit-burnt accidents
9): the machine can be moved steadily and fixed firmly with a lower gravity center and good stability during the high-speed drilling
10): it is equipped with a few operating handles, with rational layout and flexible and reliable operation
11): the hydraulic plunger chuck is adopted, with reliable clamping operation and free from damaging the drive pipe
 
XY-44AT is model developed on the basis of XY-44A, which is integrated with a hydraulic tower system
