With the rapid development of the construction and mining industries, excavators, as core construction equipment, play a crucial role in project construction. For many companies, purchasing new excavators is costly, while choosing used excavators can not only reduce investment costs but also quickly put them into production to meet construction needs. However, used equipment, due to long-term use, may have problems such as wear and tear, decreased hydraulic performance, or aging parts. Improper operation and maintenance can easily lead to reduced equipment efficiency and even additional repair costs. Therefore, mastering scientific used excavator usage techniques is crucial for improving work efficiency and extending equipment life. This article will provide a detailed analysis from four aspects: operating techniques, daily maintenance, work environment optimization, and procurement strategies, to help you comprehensively improve the efficiency of your used excavators.

Because used excavators have been used for a long time, the mechanical system may have wear and tear, and the hydraulic response may be slightly delayed. Therefore, extra care must be taken during operation. Good operating techniques can not only improve work efficiency but also effectively reduce equipment wear and tear and extend its service life. Here are some key operating techniques:
On a construction site, the movement and digging route of the excavator directly affect construction efficiency. Especially in earthmoving, trenching, or foundation excavation, without pre-planned routes, the equipment may move repeatedly or idle, resulting in fuel waste and construction delays. It is recommended to determine a reasonable route before operation based on construction drawings and site conditions, dividing the work area into several small blocks and completing the digging tasks sequentially.
For used excavators, excessive digging or frequent large-angle operations will increase the load on the hydraulic system and accelerate component wear. Operators should rationally control the digging depth and angle according to soil conditions and construction needs, avoiding high-intensity continuous operation, while improving digging accuracy and reducing rework.
While rapid robotic arm operation can improve efficiency in the short term, it will cause significant impact on the hydraulic system, bucket bearings, and bucket. A smooth, continuous operating method is recommended, especially during loading, unloading, or precision digging. Slow, continuous movements are crucial to reduce wear and save fuel.
Before starting work each day, check the control handles, pedals, rotating mechanisms, and hydraulic oil status to ensure the operating system is functioning properly. Jiecheng Used Excavator Supplier suggests that pre-operation checks can significantly reduce the risk of malfunctions and ensure smooth construction.
Modern used excavators are typically equipped with automatic limit switches, hydraulic assist, and precision positioning functions. Operators should fully utilize these functions to reduce human error and improve construction accuracy. For example, using the automatic limit switch can prevent the bucket from digging too deep, thus protecting the hydraulic system.
Maintenance is a core element of efficient operation of used excavators. A reasonable maintenance plan not only prevents malfunctions but also improves construction efficiency. The following are detailed maintenance strategies:
Hydraulic Oil Check: Weekly check to ensure the hydraulic oil level is normal, free from contamination or leaks, and the hydraulic pump pressure is stable.
Lubrication System Maintenance: Check the lubrication level of the boom, bucket, and slewing bearings daily or every 50 hours, and add lubricating oil as needed.
Air Filter Cleaning: Clean the filter element weekly to prevent impurities from entering the engine and improve fuel efficiency.
Cooling System Inspection: Check the radiator water level monthly, remove debris, and prevent hydraulic oil overheating.
Crawler/Tire Inspection: Check tire pressure and track wear daily to ensure safe operation and smooth travel.
Electrical System Inspection: Check the battery status, wiring, and lighting system monthly to ensure safety during nighttime or harsh environments.
Engine Maintenance: Change the engine oil and oil filter every 500 hours, clean the fuel filter, and maintain efficient engine operation.
Hydraulic Line Inspection: Check hydraulic hoses weekly for aging, cracks, or leaks to prevent hydraulic system malfunctions.
Through a systematic maintenance plan, used excavators can maintain high operating efficiency and reduce downtime. Especially for equipment purchased from Jiecheng used excavator suppliers, following the manufacturer's maintenance recommendations can maximize equipment performance and reduce long-term operating costs.
The construction environment directly impacts the working efficiency of used excavators. Optimizing the construction environment can reduce equipment load and improve operating speed and accuracy:
Used excavators are prone to slipping on uneven ground, increasing hydraulic oil consumption and accelerating track or tire wear. Leveling the work area in advance or laying temporary roads can significantly improve construction efficiency.
In environments where multiple machines work together, optimizing the work sequence and intervals avoids mutual interference, reduces idling and waiting time, and thus improves overall work efficiency.
Modern construction sites utilize surveying instruments, GPS positioning, and construction monitoring systems to assist operation. Using these tools with used excavators can improve digging accuracy and reduce rework rates. For example, in foundation pit construction, GPS positioning systems can help operators precisely control excavation depth and location.
During rainy seasons or high-temperature weather, care should be taken to avoid equipment slippage, hydraulic system overheating, or excessive engine load. Intermittent operation or reasonable scheduling of work hours can be adopted to ensure the equipment operates in optimal condition.
In harsh construction environments, muddy or rocky sites, accessories such as track guards and engine guards can be added to used excavators to reduce the impact of the external environment on the equipment and improve operational stability.
