10 Key Parts That Must Be Inspected before Purchasing A Second-hand Rotary Drilling Rig

The performance condition of second-hand rotary drilling RIGS is closely related to the degree of wear and tear of key parts. A comprehensive inspection can effectively avoid the risks of purchasing the machine. The following six core parts need to be given special attention.

1. Hydraulic system: Check if the hydraulic oil is turbid and if there are any signs of leakage. Test the smoothness of the operation of the hydraulic pump and cylinder. Jamming or abnormal noise may indicate severe wear.

2. Drill pipe and drill bucket: Check the wear and deformation at the connection of the drill pipe, whether the tooth seat of the drill bucket is firm, and whether there are cracks in the bucket body. These directly affect the drilling efficiency and safety.

3. Power System: Start the engine and listen to whether the running sound is smooth. Observe the color of the exhaust. Blue or black smoke may indicate that the engine is burning oil or the fuel is not burning completely.

4. Chassis and Tracks: Check the degree of wear and tightness of the track plates, and whether there are any welding repair marks on the chassis structure to ensure the stability of walking and support.

5. Operating System: Test the sensitivity of the joystick and dashboard, whether the functions of each button are normal, and whether there are any potential hazards such as aging or short circuits in the circuit system.

6. Structural components: Focus on inspecting load-bearing parts such as masts and luffing mechanisms for any deformation, cracks or excessive rust to prevent safety accidents caused by insufficient structural strength.

In conclusion, when inspecting second-hand rotary drilling RIGS, it is necessary to check each core functional component one by one, and make a comprehensive judgment based on the equipment's service life and maintenance records. When necessary, professional technicians can be invited to participate to ensure that the purchased equipment can meet the construction requirements and reduce the later maintenance costs.
