In the construction industry, excavators are essential heavy equipment, especially Hitachi brand excavators, which are favored by customers around the world for their excellent performance and durability. However, as the equipment is used for a longer time, the performance and condition of second-hand Hitachi excavators tend to decline, which also makes many potential buyers feel worried when purchasing. Today, we will explore some of the most common problems with second-hand Hitachi excavators and how to effectively prevent these problems to ensure that you can use the equipment stably for a long time after purchase.
Common problem 1: Hydraulic system failure
The hydraulic system is one of the core of the excavator, responsible for the operation of key components such as the arm and bucket. Due to long-term workload, the hydraulic system is prone to leakage, unstable oil pressure or wear of parts. This will not only affect the efficiency of the excavator, but may also lead to more serious mechanical failures.
Prevention method: When purchasing a second-hand Hitachi excavator, carefully check the various connection points of the hydraulic system, especially the status of the hydraulic pipes, joints and pumps. At the same time, ask the seller to provide maintenance records of the hydraulic system to ensure regular inspections and oil changes. In addition, the quality and oil level of the hydraulic oil should be checked regularly during use to detect potential problems in time.
Common Problem 2: Engine Failure
The engine is the power source of the excavator. Once a failure occurs, the performance of the entire equipment will be greatly reduced. If the engine of a second-hand Hitachi excavator is not fully maintained, it may have problems such as difficulty in starting, insufficient power, and increased fuel consumption.
Prevention method: Before purchasing, ask professionals to conduct a comprehensive inspection of the engine to check whether the engine’s compression, cooling system, and fuel system are normal. By checking the engine’s working hours and maintenance records, ensure that the engine is not excessively worn and has not experienced serious failures. In addition, regular replacement of engine oil, air filters, and fuel filters is the key to ensuring long-term stable operation of the engine.
Common Problem 3: Chassis Wear
The chassis is the supporting part of the excavator. As the use time increases, chassis components such as tracks, drive shafts, and chains are prone to wear, which in turn affects the stability and work efficiency of the excavator. If the chassis is seriously damaged, it may require high repair costs.
Prevention method: Regularly check the wear of the tracks and chassis, especially the parts with more severe wear. If a problem is found, replace or repair it as soon as possible to prevent the problem from further expanding. In addition, keep the chassis clean to prevent dirt, stones and other debris from entering the components to reduce unnecessary wear.
Common Problem 4: Electrical System Failure
Electrical system failure usually manifests as failure to start, instrument panel failure or electronic control system failure. Since there are a large number of electrical connections and control modules involved in the excavator, once there is a problem with the electrical system, the equipment will not work properly.
Prevention method: Before purchasing, carefully check each contact and cable of the electrical system to ensure that there is no corrosion, looseness or wear. Check the battery voltage regularly and ensure that the electrical components and lines are well protected. If there is any abnormality, replace or repair it in time to avoid the problem affecting the normal operation of the equipment.
Buying a high cost performance used Hitachi excavator can save you a lot of money, but it also requires you to pay more attention to the details of the equipment to avoid potential problems affecting its later use. By regular inspections, timely maintenance and choosing reliable suppliers, you can greatly reduce the risk of hidden problems and ensure the stability and efficiency of the equipment in long-term use. Whether it is the hydraulic system, engine, chassis or electrical system, you need to conduct a comprehensive inspection before purchase and maintain good maintenance habits during use.
