In the trading of second-hand rotary drilling RIGS, "accident machines" often hide many hidden dangers, posing huge risks to subsequent use. Mastering effective troubleshooting techniques for fault history can help buyers avoid traps and purchase reliable equipment.
1. Check the fuselage structure. Focus on inspecting the welds of key parts such as the large arm and the chassis. If there are irregular repair welds or abnormal plate thickness, it may have experienced severe collisions. At the same time, observe whether the structural components are distorted or deformed. This is an important basis for judging the accident.
2. Check the hydraulic system. If the hydraulic oil is blackish-brown and contains impurities, it may cause component wear due to a malfunction. Check if there are any signs of frequent replacement at the oil pipe joints. Excessive maintenance may indicate that the system has been leaking oil for a long time.
3. Test the power system. After starting, listen to the engine's running sound. Abnormal noises may be caused by damage to internal parts. Check the color of the smoke from the exhaust pipe. Abnormal blue or black smoke may be associated with serious mechanical failure.
4. Nuclear maintenance records. Complete maintenance documents are required. Be vigilant if key time node records are missing. By comparing the maintenance items with the vehicle's age, frequent major overhauls may indicate hidden dangers in core components.
5. Test key performance. Operate the drilling rig for a test drill and observe whether the drilling speed is uniform. Any jamming may indicate unrepaired issues. Check the coordination of movements such as rotation and lifting. Abnormal sluggishness indicates a fault in the transmission system.
6. Inquire about the usage environment. Find out whether the equipment has been operating under harsh conditions for a long time, such as frequent construction in hard rock strata, which can accelerate wear and tear. Ask the previous user about their operating habits. Rough operation is prone to cause hidden malfunctions.
In conclusion, when investigating the fault history of second-hand rotary drilling RIGS, it is necessary to take into account both detailed observation and performance testing, and make a comprehensive judgment based on maintenance records and usage background. Multi-dimensional verification can minimize the risk of purchasing "accident machines" to the greatest extent and ensure the smooth progress of subsequent construction.
