As a world-renowned excavator brand, Doosan has been widely used in various engineering projects with its excellent performance, reliability and durability. In the second-hand market, Doosan excavators have become the first choice for many companies due to their good reputation and stable working performance. However, choosing a second-hand Doosan excavator with good performance is not easy, and several key factors need to be paid attention to during the purchase process.
1. Understand the different models and specifications of Doosan excavators
First of all, understanding the different models and specifications of Doosan excavators is the basis for purchase. Doosan excavators have multiple series, including mini, medium, large, etc., and each series is adapted to different working environments and tasks. For example, mini excavators are suitable for urban construction or small space operations, while medium and large excavators are mostly used for heavy operations such as earthworks and mining.
When choosing a second-hand Doosan excavator, you need to choose the right model according to your specific work needs. If you are doing daily small construction projects, a mini or medium Doosan excavator is enough; if it involves large-scale infrastructure construction, you may need to choose a more powerful large excavator.
2. Check the age and working hours of the equipment
The age and working hours of a used excavator are key indicators for evaluating its value and performance. Generally speaking, Doosan excavators with fewer years and working hours have longer remaining service life, so their prices are higher. Most used excavators generally do not work for more than 6,000-8,000 hours. Equipment that exceeds this time may require more repairs and maintenance, and the price will also drop.
When purchasing a used Doosan excavator, you should ask the supplier to provide the equipment's working hours record and confirm whether the equipment has had a serious failure or repair history. This can help you judge the actual use of the equipment and avoid purchasing equipment that has been working for too long or poorly maintained.
3. Carefully check the equipment's maintenance and maintenance records
Good maintenance records are the guarantee of long-term and stable operation of used Doosan excavators. Formal suppliers usually provide equipment maintenance and maintenance records, detailing the items and dates of each maintenance and repair. Through these records, you can understand the maintenance of the equipment and whether there have been major repairs.
Ideally, the equipment is regularly inspected and maintained without serious failures or damage. In particular, you need to focus on checking the maintenance of key components such as the engine, hydraulic system and chassis. Make sure these components have not been significantly worn to extend the service life of the equipment.
4. Check the appearance and working performance of the equipment
Appearance and working performance are important bases for you to evaluate a used Doosan excavator. Equipment with good appearance usually means that it has been well maintained for a long time and has not suffered large-scale accidents or damage. When checking the appearance of the equipment, you need to pay attention to the chassis, body and bucket of the equipment to see if there are obvious cracks, deformation or rust.
In addition, you also need to conduct on-site testing to check the working performance of the equipment. Including engine start-up, hydraulic system response speed, bucket operation is smooth, brake system sensitivity, etc. These directly affect the working efficiency and safety of the equipment.
Summary
Buying a used Doosan excavator is a decision that requires careful consideration. Only by fully understanding the brand, model, working hours, maintenance status and other factors of the equipment can you find a perfect equipment. By paying attention to these details and choosing a reputable second-hand excavator wholesaler, you can minimize the purchase cost while ensuring the quality of the equipment and ensure the smooth progress of your project.
