YQZ-50A hydraulic core drilling rig
1.Introduction of YQZ-50A hydraulic core drilling rig
YQZ-50A hydraulic core drilling rig is a high, medium and low speed drilling rig with hydraulic pressure feeding. The rig is suitable for geological drilling of complex terrain such as mountains, hills and rivers, engineering geological survey of buildings, and drilling of blast holes. In order to meet the needs of different users, the rig can be equipped with one of three powers of diesel engine, gasoline engine or electric motor. The default is diesel engine power.
2. Features of YQZ-50A hydraulic core drilling rig
- This model of light weight drilling rig is compact, small and lightweight. The rig can also be dismantled quickly, making it easier to carry the mountain, especially for complex terrain such as mountains and hills.
- Compared with similar products, this type of portable drilling rig is equipped with a double cylinder hydraulic feeding system, which has a fast drilling speed and high work efficiency.
- This type of portable drilling machine operation panel is equipped with a pressure gauge at the bottom of the hole to indicate the pressure, so that the operator can adjust according to different terrain conditions.
- This model of lightweight drilling rig is equipped with a high-performance 4-speed shifting system. It is convenient for the operator to adjust the forward rotation speed according to the geological conditions. In addition, it is equipped with an ultra-low speed reverse gear, which is convenient for the operator to disassemble the drill pipe.
- The rig is equipped with a fixed clamping mechanism and an integrated main rod, which eliminates the need for a rig and makes the work more compact.
