Tiedou excavator recommendation (fourth issue) Yanmar 2-3 ton excavator parameter configuration and specification information

　　The previous issue mainly introduced Yanmar's Mini within 1 ton. This issue introduces 2-3 tons as the main market for Mini excavators. This tonnage can be used in various types of working environments. These models still do not have a cockpit installed, so users who need to work outdoors still need to purchase them separately for self-installation or manufacturer customization. Due to problems such as engine power, excavators still do not have the ability to install refrigeration equipment. Avoid working outdoors for a long time in high temperature or severe cold weather as much as possible.

　　2-3 tons has always been a highly concerned model in the Mini excavator market, especially the retractable chassis function of the Mini excavator has a certain ductility in narrow spaces. The detachable awning can also be manually operated for work types that require height. There are many main types of work for this type of model. Compared with excavators within 1 ton, it can be installed for higher-level engineering operations. At the same time, the scalability of 2-3 tons Mini excavators for farms and manors is very high.

　　Tiedouy used the excavator market in the export trade in the first half of 2024. The demand for Mini excavators was 56%, requiring 20-30 models of excavators, and 37% for 30-50 models. The consultation and export volume of Mini excavators under 1 ton only accounted for 17% of the total market. Yanmar has a very important performance and outstanding capabilities in the Mini excavator market.
