The Doosan DX225LCA is a 22-ton class crawler excavator widely used for various excavation, lifting, and general construction tasks. It's known for its robust structure, powerful performance, and user-friendly design. This excavator is typically equipped with a Doosan-developed engine (such as the DL06 in newer models), capable of delivering high power and torque to meet demanding applications. This translates to strong digging force, efficient operation, and shorter work cycles.

DX225LC is Doosan's 22-ton DX series excavator. Compared with the DH series, the DX series has made great improvements in many aspects such as the layout of hydraulic pipelines, and the appearance design is closer to the European version. It is one of the best-selling product models on the market. This specification excavator is often used in common earthwork construction.

The Hyundai R60-9S is a compact excavator designed for versatility and efficiency in confined spaces. This machine is part of Hyundai's 9S series, which represents advancements in performance, operator comfort, and fuel efficiency. The R60-9S is commonly used in urban construction, landscaping, utility work, and other applications where space is limited but digging power is still required. Its compact dimensions and zero-tail swing design allow it to operate effectively in tight work areas and close to obstacles.A key focus of the R60-9S design is operator comfort and safety.

The 326D Excavator is a highly efficient medium-sized excavator designed for heavy-duty construction tasks. Equipped with a powerful engine that delivers excellent power output to handle a wide range of complex conditions, the 326D is equipped with an advanced hydraulic system that improves digging and handling efficiency for more productive work. Its spacious and comfortable cab provides operators with good visibility and convenient controls, making long hours of work easier. In addition, the model has excellent fuel economy, which can effectively reduce operating costs.

2. Operating PrincipleThe excavator operates through a complex hydraulic system. Hydraulic cylinders move the boom, arm, and bucket, allowing for smooth and powerful actions. The operator uses levers or joysticks in the cab to control the flow of hydraulic fluid, which in turn moves the different parts of the excavator.
