XY-44 drilling rig

1high torque for low speed 2 good drill capacity 3 heavy but easy to disassemble 4simple construction reasonable layout

xy-44 can be used either for engineering geological survey, exploring of shallow petroleum natural gas , underground water or for engineering hole drilling of dam grouting and gallery ventilation and water exhaustion .

 

Main character

1.  With rather high speed and reasonable speed range with a few steps, high torque for low speed, it is suitable for small hole diameter core drilling of diamond mine, and also for large hole diameter core drilling of carbide alloy mine and various engineering drilling.

2.  It has good drill capacity. With Φ71 wire-line drilling rod, its max. depth is 1000m

3.  It is not so heavy and is very easy to disassemble. It can be knocked down into 10 package units, with the heaviest unit weighing only 300 kg. Hence it is convenient for transport and adaptive to operation in mountain areas.

4.  It features simple construction and reasonable layout. All the units are exposed outside without any mounted on top of another, so it is easy for maintenance and repair.

5.  It has two oil cylinder feeding, length stroke (max. stroke is 600mm), for the sake of safety and labour-saving in handling any accident.

6.  It is smooth in travel of the rig and can be fixed firmly. The frame is rigid with high stability in high speed drilling.

7.  It is equipped with sufficient meters for indicating the conditions in the hole and with only a few operating handles for flexible and reliable operation.
