Factory Price used Cat 320BL 20ton used excavator Japan Original Cat 320BL 330BL for sale

Detailed description of Caterpillar 320BL excavator:

1. Basic parameters and performance

Tonnage and weight: It is a medium-sized excavator of 20-22 tons, and the working weight of the whole machine is about 21,500-22,000 kg.

Bucket capacity: The standard bucket capacity is 0.9-1.2 m³ (different specifications can be selected according to the operation requirements).

Engine configuration:

Equipped with Caterpillar C4.4 ACERT electronic control engine, rated power 110-120 kW (about 150-160 horsepower), with low speed and high torque characteristics.

The fuel tank capacity is about 400 L, which supports long-term continuous operation.

Environmental protection standards: It meets Tier 3/National III emission standards, optimizes combustion efficiency through ACERT technology, and reduces emissions and fuel consumption.

2. Core performance features

Hydraulic system:

Adopts dual pump + single gear pump hydraulic system, the maximum flow of the main pump is 220 L/min, the main overflow pressure is 34.3 MPa, the response speed is fast, and the compound action is smooth.

The boom/arm regeneration circuit design reduces energy loss and improves cycle efficiency.

Digging capacity:

The maximum digging depth is about 6,500 mm, the maximum digging radius is about 9,800 mm, and the bucket digging force is about 150 kN.

The walking speed is 4.8-5.5 km/h and the rotation speed is 10.5 rpm, which can adapt to various working conditions and terrains.

3. Structure and design

Stability and durability:

The track width is 600 mm and the ground length is optimized to enhance the stability of wetlands and rugged terrain.

Reinforced X-type frame and track guard reduce stress concentration and extend service life.

Cab and operation:

ROPS/FOPS certified cab, equipped with suspension seat, LCD display and multi-function joystick, comfortable and intuitive operation.

Low noise design (cab noise ≤ 70 dB), reducing operator fatigue.

4. Market positioning and applicable scenarios

Versatility: supports hydraulic quick-change interface, adapts to buckets, breakers, grabs and other accessories, suitable for:

Municipal engineering (pipeline laying, greening construction)

Construction sites (earth excavation, foundation treatment)

Agriculture and water conservancy (ditch cleaning, land leveling)

Economy: fuel consumption is 10-15% lower than that of earlier models, combined with intelligent power management mode to optimize operating costs.

Production background: mainly produced in Caterpillar China factories (such as Xuzhou base), and some core components use global supply chains.

Supplementary explanation

Differences from 320D: 320BL is an economical long-arm version ("BL" may stand for "Boom Long"), which has a longer boom length than the standard 320D, suitable for deep digging and long-distance operations, but with slightly lower power parameters.

Maintenance advantages: modular design simplifies daily maintenance, and the filter element and oil filling points are centrally arranged to reduce maintenance costs.
