Original Used Medium Excavator Caterpillar CAT315DGC Secondhand CATHydraulic Middle Crawler Backhoe Digger Used Excavator

The Caterpillar 315DL excavator is a medium-sized excavator produced by Caterpillar Inc. in the United States. Its design takes into account efficient operation capabilities and flexibility, and is suitable for a variety of scenarios such as earthwork engineering and mining. The following describes its core features from multiple dimensions:

1. Equipment positioning and brand background

Tonnage and capacity:

Although the model is marked as "15 series", its whole machine working weight is 17.28 tons, which belongs to 17-ton equipment, and its performance is comparable to other brands of 20-ton excavators, with stronger operating efficiency.

Manufacturer:

Caterpillar was founded in 1925 and is headquartered in Illinois, USA. It is a world-leading manufacturer of construction machinery, mining equipment and diesel engines.

2. Core parameters and performance

Power system:

Equipped with Caterpillar CAT C4.2 ACERT engine, rated power 91kW/speed, 4-cylinder design, displacement 4.3L, taking into account power output and fuel economy.

Hydraulic system:

The maximum flow of the main pump is 150L/min, and the main overflow pressure is set to 35MPa to ensure efficient hydraulic power output;

The boom, dipper rod, and bucket cylinders are designed with 2-110×1193mm, 1-120×1331mm, and 1-100×1048mm, respectively, to provide stable operating torque.

Operation performance:

The maximum digging depth is 5720mm, the maximum unloading height is 6140mm, and the maximum digging radius of the parking surface is 8430mm;

Travel speed is 5.6km/h, rotation speed is 10.2rpm, and ground pressure is 40.7Kpa, which can adapt to complex terrain.

3. Structure and capacity

Main body size:

Total transport length is 8520mm, width is 2590mm, height is 2930mm, and track shoe width is 600mm, taking into account both transportation convenience and operation stability.

Oil capacity:

The fuel tank is 300L, and the total capacity of the hydraulic system is 190L, which supports long-term continuous operation;

The engine oil replacement volume is 17.5L, and the coolant capacity is 22L, and the maintenance cost is controllable.

4. Application scenarios and advantages

Applicable fields:

Suitable for earthwork excavation, mining, municipal construction and other scenarios. The backhoe design (bucket capacity 0.61m³) takes into account both efficiency and precise control.

Competitiveness:

With a weight of 17 tons and a working capacity of 20 tons, it has a higher cost performance and operation coverage among the same level of equipment.
