Buying a used excavator can be a cost-effective investment for a construction company. However, it is essential to examine several elements before making a purchase. An excavator is a piece of heavy equipment that requires intensive inspection to ensure that it still works correctly. The following factors are critical in identifying a quality used excavator that meets your company's needs.
Inspection of the Frame and Body
Inspecting the excavator's frame and body is the first step towards identifying the machine's dependability. The frame should be in good shape, free of any cracks or welds. When inspecting the body, ensure that all panels are straight and that there are no dents or signs of welding. Inspect the undercarriage for wear and tear, as the condition of the undercarriage can impact the machine's performance. If possible, check the wear of the tracks, shoes, rollers, pins, and sprockets.
Examining the Engine and Hydraulics
It is vital to carefully inspect the excavator's engine and hydraulics. One of the first things to check on the engine is the oil level, which should be between the minimum and maximum levels. Make sure to start the engine and listen for any unusual sounds or vibrations. Inspect air filters, radiators, hoses, and belts. Examine the hydraulic system by raising and lowering the excavator arm, checking for any leaks or damaged hoses. Look out for any signs of rust or corrosion, which can indicate poor maintenance.
Checking the Cabs and Controls
The cab is a crucial factor when considering the operator's comfort and safety. Inspect the cab's floor, seat, foot pedals, and control levers for any signs of wear and tear. Check if the windows and mirrors are in good condition, and test the cab's air conditioning and heating systems. Ensure that all the controls are working correctly by moving the joysticks, pressing the pedals and buttons, and observing the machine's response.
Test Driving the Excavator
Before making a purchase, ensure that you test drive the excavator on different terrains to check its performance capabilities. Start with a flat surface, then move on to rough and uneven surfaces to verify that the excavator can handle challenging terrains. During the test drive, pay attention to the machine's acceleration, steering, and braking system. Listen for any unusual sounds or vibrations and observe the engine temperature and oil pressure.
Conclusion
In conclusion, when considering purchasing a used excavator, thorough inspection is crucial in ensuring that you make the right investment. Check the frame and body of the machine, examine the engine and hydraulics, inspect the cab and controls, and test drive the excavator on various terrains. Do not hesitate to ask for a professional mechanic's opinion if you are unsure about anything. Remember that a good quality excavator is an investment that can significantly impact your construction projects' productivity and success.
