As a world-renowned construction machinery brand, Carter excavator is recognized by the industry for its performance and durability. In particular, the combination of three Carter excavators is excellent in large-scale engineering operations. So, what is the total weight of these three Carter excavators? The answer to this question depends on the specific model configuration. For example, the Carter 320D excavator weighs about 22 tons per unit, the Carter 336GC excavator weighs about 34 tons, and the larger Carter 390F excavator weighs 90 tons. If we are talking about a combination of excavators of these three models, then the total weight will reach about 146 tons. Of course, this is only an estimate based on a specific model, and the actual weight needs to be calculated precisely based on the specific configuration and additional equipment of each excavator. Therefore, when considering the total weight of the three Carter excavators, we need to pay attention to the technical parameters of each machine to ensure that the load-bearing constraints of the construction site and the construction efficiency requirements are met, so as to achieve the best engineering operation results. In conclusion, it is very important to understand and accurately grasp the tonnage data of different models of Carter excavators, which is of significant significance for optimizing resource allocation and improving engineering efficiency.
