Comment prolonger la durée de vie de votre pelle Doosan DH300 d'occasion

As an important engineering equipment, the service life of a used Doosan DH300 excavator directly affects work efficiency and project costs. Correct maintenance and use methods are essential to extend the life of the equipment. Over time, the equipment will inevitably wear and age, but through scientific maintenance and meticulous operation, the failure rate can be effectively reduced and the aging process of the equipment can be delayed. This article will explore how to extend the service life of a used Doosan DH300 excavator through daily maintenance, operating habits, and storage methods.

Regular equipment maintenance and inspection are the basis for extending the life of the excavator. First, the engine oil, hydraulic oil, and filter need to be replaced on time. The replacement of these fluids helps reduce wear on the machine parts and improve the working efficiency of the engine. In addition, the hydraulic system should be checked for normal operation and leakage in the oil circuit to ensure that the pressure and flow of the hydraulic system meet the requirements. Replace damaged parts in time to prevent small problems from turning into major failures.

Reasonable operation is another important factor in extending the service life of the excavator. During operation, avoid overloading and sudden acceleration or braking, and try to avoid overloading the excavator. Operators should choose the appropriate working mode according to different working environments and avoid long-term high-load operations. At the same time, sudden stops or violent operations should be avoided during operation, and a smooth operating rhythm should be maintained to reduce the impact on mechanical parts.

The environment has a significant impact on the service life of a used excavator. First of all, the excavator should be used as far as possible to avoid operating in adverse weather conditions, such as high or low temperature environments, which may cause engine overheating or oil viscosity changes, affecting the efficiency of the hydraulic system. In humid or dusty environments, it is particularly important to clean the equipment regularly, especially the air filter and radiator, to prevent dust or dirt from accumulating and affecting the heat dissipation and ventilation of the machine.

The tracks and chassis are key components of the excavator, which directly affect its stability and work efficiency. Check the wear of the tracks regularly to ensure that the track tension is moderate and avoid being too loose or too tight. The chassis inspection should pay attention to whether there are cracks, loose parts or damaged bearings, and repair or replace damaged parts in time to prevent equipment damage caused by chassis failure.

When the excavator is not in use, the correct storage method can also extend its service life. The excavator should be parked in a dry, well-ventilated place, avoiding exposure to rain and snow to reduce the corrosion of the machine by external factors. At the same time, the equipment can be started regularly during storage and run without load for a short period of time to keep the engine’s lubrication system working normally and avoid aging of engine parts due to long-term non-use.

Proper storage of second hand Doosan DH300 excavators is a key step to ensure their long-term and efficient operation. By choosing an appropriate storage environment, regular inspection and maintenance, the service life of the equipment can be effectively extended and the operating cost can be reduced. Whether it is short-term or long-term storage, careful maintenance and management can make the excavator play a greater role in future work and maintain its stability and efficiency.
