The core components (such as the engine and hydraulic main pump) are designed to be robust and durable, with a relatively low failure rate, making them the epitome of “sturdy and durable” in the construction machinery field.
In the second-hand market, Caterpillar equipment, especially the D series, has a much higher preservation rate than most of its competitors.

Although the initial purchase cost may be high, its long lifespan, low failure rate, low fuel consumption and ease of maintenance make the total cost over its entire lifecycle very competitive.
Caterpillar has the most comprehensive network of agents and a complete parts supply system worldwide, ensuring prompt service and maintenance for the equipment.

Conducting roadbed excavation, ditch digging, slope modification, material transportation and backfilling. Its powerful excavation force and stable control enable efficient transfer of earthwork.
Responsible for site leveling, foundation pit excavation, basement excavation, pipeline trench excavation and backfilling. Its diverse combinations of boom and bucket can meet different depth excavation requirements.
During these high-intensity continuous operations, its low failure rate ensures the completion of the project schedule, the relatively low fuel consumption significantly reduces operating costs, and the fast cycle time enhances overall efficiency.

Construction or maintenance of sewers, water supply pipes, gas pipes, and cable trenches. Precise control of excavation depth and width is required. The 320D pilot hydraulic control and pressure compensation system can achieve sub-millimeter level precision operations.
Utilizing various tools (such as hydraulic tampers), carry out terrain shaping, excavation of tree planting pits, and excavation of ponds, etc.

clearing the working face, separating the ore, repairing roads, and loading trucks. Its sturdy structure can withstand harsh working conditions.

loading and classifying loose materials such as sand, gravel, coal, and scrap steel. The rapid and powerful combined actions can shorten the loading time.
