Choosing the right brand and model of экскаватор б/у is very important to ensure the performance, service life and after-sales service of the machine. Here are some key factors that can help you make a wise choice:
1.Understand the use requirements
Working environment: Choose the right model according to the working environment where you plan to use the excavator. For example, different scenarios such as urban construction, mining, and road construction have different requirements for excavators. Places with small working spaces may need to choose a more compact model.
Nature of work: Different models of excavators are suitable for different types of operations, such as earthwork excavation, stone mining, infrastructure construction, etc., and need to be selected according to the weight, depth and accuracy of the operation.
2.Choose a well-known brand
Some well-known brands second-hand excavators are usually of better quality, with higher liquidity in the second-hand market and a complete after-sales service system. The following are several common and popular excavator brands:
Caterpillar: As the world’s leading heavy equipment manufacturer, Caterpillar excavators are known for their durability and stable performance. There is a large demand in the second-hand market and a relatively rich supply of accessories.
Komatsu: A Japanese brand that provides efficient and reliable excavators suitable for a variety of complex working conditions. If the second-hand equipment is properly maintained, it will have a long life.
Hitachi: Another major Japanese brand. With high-tech engines and hydraulic systems, Hitachi’s excavators are known for their precision and efficiency, and are suitable for high-precision operations.
Volvo: A Swedish brand, Volvo excavators are sold with comfort and safety, low fuel consumption, strong environmental protection, and suitable for long-term operations.
3.Consider the number of working hours (man-hours) of the machine
The number of man-hours of a second-hand excavator is a very critical reference indicator. Generally speaking, the higher the age and man-hours of the machine, the greater the probability of failure. It is usually recommended to choose a second-hand excavator with a man-hour of between 2,000 and 5,000 hours.
Too high a number of man-hours (for example, more than 8,000 hours) may mean that the equipment requires more repairs and maintenance, so pay special attention to the maintenance records of the machine.
4.Check the machine’s maintenance and repair records
Choose used excavators with complete repair records, especially if the equipment has replaced important parts (such as the engine, hydraulic pump, etc.), which means that the machine has been well maintained and reduces the risk of overhaul.
Make sure that the equipment has undergone regular maintenance such as oil change and filter element replacement on time.
5.Consider the availability of parts
Some brands of excavators have more abundant parts supply worldwide. Purchasing used equipment of these brands can reduce the difficulty and cost of future repairs.
Some brands may be less common in certain areas. If repairs and parts are difficult to obtain, it may increase the cost of use.
6.Compare the performance of different models
Under the same brand, different models of excavators have different performance and configuration. You need to choose the right model according to your specific needs. For example, small excavators are suitable for urban construction, and large excavators are suitable for mining or stone mining.
Pay attention to the equipment’s maximum digging depth, digging force, operating comfort, fuel consumption and other parameters, and choose the model that best suits your needs.
7.Consider the value retention of the second-hand market
The value retention of excavators of different brands and models in the second-hand market varies greatly. Generally, world-renowned brands such as Caterpillar and Komatsu have good second-hand market liquidity and high residual value.
In the second-hand market, some brands and models of equipment are easier to resell or replace due to large market demand, and have better value retention.
8.Consider the comprehensive cost-effectiveness of the equipment
In addition to looking at the brand and model, it is also necessary to make a comprehensive assessment of the overall cost-effectiveness of the equipment. Considering factors such as purchase price, maintenance cost, fuel consumption, and accessory price, choosing equipment with high cost-effectiveness will minimize the long-term use cost.
9.Consider after-sales service
Some brands of excavators have more complete after-sales service guarantees in the second-hand market. When purchasing, it is also very important to understand the content of after-sales service (such as warranty period, whether technical support can be provided, etc.).
When choosing a suitable second-hand excavator brand and model, you should first consider your operating needs, and then make a comprehensive assessment based on the equipment’s usage status, brand market reputation, maintenance records, and equipment cost-effectiveness. Choosing equipment from well-known brands can provide you with better performance guarantees and after-sales support, and comparing the characteristics of different models will help you find the equipment that best meets your needs.
Through careful investigation and comprehensive consideration, you can ensure that you choose a second-hand engineering equipment that suits you and avoid high-risk investments.
