When choosing an excavator, the following key factors need to be considered:

Construction area and engineering requirements: Soil differences in different regions can affect the applicability of excavators.
For example, the soil in Northeast China is relatively hard, and Carter and Komatsu excavators are more suitable;
And the soil in North China is soft, so brands such as Shengang, Hitachi, and Sumitomo are also worth considering.
In addition, the scale of the project and the operating environment (such as soil hardness, workload, transportation distance, etc.) will also affect the choice of 12.

Excavator parameters: including overall weight, bucket capacity, boom and boom length, and engine power.
The larger the weight, the better the stability, suitable for large-scale projects;
Smaller excavators are more suitable for working in narrow spaces.
The capacity of the bucket affects the amount of soil excavated in a single excavation, the length of the boom and arm affects the operating range and flexibility, and the engine power directly affects the power performance of the excavator.

Brand and Model: Choosing well-known brands such as Caterpillar, Komatsu, Hitachi, etc. usually means higher quality and better after-sales service.
Excavators of different brands and models have different configurations and performance characteristics, and the most suitable model should be selected according to engineering requirements.

Cost effectiveness: Consider purchasing costs, operating costs (such as fuel consumption, maintenance costs), and revenue situation.
The price of brand new equipment is relatively high, but it has the best performance;
Second hand equipment has a lower price, but its usage and maintenance records need to be carefully checked.

Matching of existing equipment: Ensure that the selected excavator matches the operational efficiency of existing equipment, avoiding the situation of “small horse pulling big cart” or “big horse pulling small cart”.

Safety considerations: Ensure that the excavator meets safety standards, is equipped with necessary safety devices, and considers operator safety training and protective measures.

Suppliers and service providers: Choose reputable suppliers and service providers, understand their after-sales service policies, such as warranty period, repair response time, and parts supply, etc
