Komatsu is a world-renowned construction machinery manufacturer, which produces various types of construction machinery. Today, we mainly introduce the Mini excavator in the excavator series. Komatsu Mini excavator has been updated for many generations. The excellent appearance design and very high user evaluation make this excavator very popular among users in the industry. The four models introduced by Tiedou today are relatively unpopular. Mini excavators within 1 ton are rarely used in actual work. Except for special needs, this type of excavator is actually the same as children's toys in the eyes of ordinary people. This type of excavator is mainly used for indoor work in enterprises and users such as farm orchards or manors.
The smaller size can be easily moved in the elevator. It is also very easy to move by operating the stairs. There is still a certain market for Mini excavators within 1 ton for interior decoration, family vegetable orchards or small canals, and installation of hydraulic crushing for internal structure transformation. Of course, some people still like manual labor, but it cannot be said that machinery brings more efficiency and convenience. High fuel economy and the new pure electric mode further reduce the cost of use and are more suitable for use in cities.Komatsu

Main differences
Engine type and power:
PC01-1 uses Kubota OC60 engine, which has less power and is suitable for light work.
PC05-1 uses Kubota D722 engine, which has slightly more power.
PC05E-1 uses electric motor, which has the same power as PC05-1 and is suitable for working environments with higher environmental requirements.
The PC09-1 uses a Komatsu 3D67E-1 engine with the highest power for heavier tasks.
Displacement and fuel type:
The PC01-1 and PC05-1 have smaller engine displacements and use diesel fuel.
The PC05E-1 uses an electric motor and relies on batteries for power, without the need for fuel.
The PC09-1 has a larger engine displacement and uses diesel fuel.
Hydraulic system pressure:
The PC01-1 has the lowest hydraulic system pressure at 14.7 MPa.
The PC09-1 has the highest hydraulic system pressure at 17.2 MPa, indicating that its hydraulic system is more powerful and suitable for higher load work.
Operating weight and operating capacity:
The PC01-1 is the lightest and is suitable for very narrow or light working environments.
The PC09-1 is the heaviest and has the highest operating capacity, suitable for occasions that require greater digging and lifting capabilities.
Although the above four Mini excavators have been introduced before, users may have a certain understanding of the parameters and actual performance. For users, Mini excavators under 1 ton are not competent for large farms and orchards. Users in need can upgrade their equipment to Mini excavators of about 2-3 tons. Excavators under 1 ton are more suitable for interior decoration and structural transformation or small-scale construction of buildings. Of course, users who like to transform and upgrade their surroundings can buy one and enjoy the fun. Pure electric equipment is recommended here. For urban infrastructure, the performance of Mini excavators is relatively useless and the work efficiency is slow. Different projects should choose the construction machinery that suits them.
