In the world of construction, excavators are indispensable. They move massive amounts of earth, dig trenches, and perform tasks that would be nearly impossible by hand. When it comes to purchasing an excavator, many opt for used machines to save on costs. However, owning a used excavator comes with its own set of challenges, particularly in the area of maintenance and repairs. This blog post, Yonggong will explore the complexities of repairing used excavators, discuss different brands, and offer valuable insights into keeping your machine in top condition.
Purchasing a used excavator can save you a significant amount of money. New machines come with a hefty price tag, and opting for a used model can lower your initial investment substantially. This allows businesses to allocate funds to other critical areas, such as hiring skilled operators or investing in additional equipment.
New excavators depreciate quickly, losing a chunk of their value within the first few years of operation. By choosing a used excavator, you avoid the steepest part of the depreciation curve, ensuring that your machine retains its value for a longer period.
The market is saturated with high-quality used excavators. Brands like Komatsu, Caterpillar, Hitachi, and others manufacture machines built to last, meaning even older models can still perform efficiently with the right care and maintenance.
Hydraulic systems are the lifeblood of any excavator. They power the arm, bucket, and other components. Issues in the hydraulic system can range from minor leaks to complete failures, requiring either simple seal replacements or comprehensive overhauls.
The undercarriage bears the brunt of the excavator’s workload, supporting its weight and facilitating movement. Over time, tracks, rollers, and idlers can wear out, leading to reduced efficiency and potential machine downtime if not addressed promptly.
