How to transporting and handling wire ropes.
Correct way: In lifting, apply the wire rope to the axle hole of the wire rope pan, or use steel pipe to penetrate the axle hole, then set the buckle on the steel pipe at both ends.
As the summer approaches, the heat will have a detrimental effect on the performance of the excavator. So, what should we pay attention to in order to maintain the performance of excavators? Besides the regular maintenance of the excavator, make sure that each component is inspected as well.
A hydraulic system is one of the most common parts of heavy machinery, not only excavators but also lifting equipment, mining machines, and other heavy equipment. There is no denying that the hydraulic pumping system is easy to control and helps machine owners reduce around 80% of oil consumption than pneumatic systems, however, the maintenance costs are very expensive when the hydraulic pump fails.
The water pump is crucial for the cooling system of heavy equipment, preventing overheating issues. Customers often face breakdowns due to overheating, especially in hot weather, and seek to reduce repair costs. Proper repair involves removing old components, cleaning the housing, and installing new parts using a hydraulic press. If unsure about the repair steps, you can replace the entire water pump at a lower cost through FridayParts.
The final drive, consisting of a hydraulic motor and gearbox, is crucial for heavy equipment as it transfers power to the undercarriage tracks. Maintenance is essential due to the high replacement cost. Common causes of failure include water contamination and damaged seals, which reduce lubrication. Regular oil checks and changes are vital, as old or contaminated oil can lead to failure. The frequency of oil changes depends on the machine type and usage, but checking oil quality frequently is recommended, especially after operating in mud or water.
Store equipment in the shade to prevent overheating and reduce operation during peak sunlight hours. Ensure air conditioning is used properly by keeping doors and windows closed and regularly checking filters. Monitor water temperature gauges and allow the machine to cool before shutting it off. Check oil quality daily to prevent deterioration, and maintain battery power by storing it properly and charging it regularly.
Regular maintenance of excavator undercarriage components is crucial to prevent efficiency loss and excessive wear. Key tips include checking and tightening bolts on track shoes, promptly replacing bent track shoes, inspecting and replacing damaged chain guards, monitoring sprocket wear and avoiding frequent backward operation, maintaining proper track tension based on terrain, and keeping the undercarriage clean.
Most excavator operators encounter various failures during operation, with the most common issue being that the excavator won’t start. This article explores possible reasons and solutions for this problem, focusing on how to inspect the electrical and engine oil circuits.
For most hydraulic excavators, the operating speed is inversely proportional to the load during digging. However, if the hydraulic pump control system is malfunctioning, the excavator cannot work efficiently under different working conditions. Therefore it is essential to know the excavator control system from different manufacturers, such as Komatsu CLSS system, CAT electronic power control system……
To check the speed drop of an excavator, start by testing the engine’s output power. If it’s lower than the rated power, inspect components like air valves, fuel injectors, the turbocharger, and the hydraulic pump. Common issues include poor fuel quality, low fuel pressure, incorrect valve clearance, and turbocharger carbonization. If the engine’s output power is normal, ensure the hydraulic pump’s flow rate matches the engine’s output. Speed issues may also stem from the pump control system, requiring checks of the electrical, hydraulic, and mechanical transmission systems.
