CAT 320D2 L Excavator Used for Earthmoving Operations and Site Preparation

Transition from digging trenches to loading trucks with a used CAT 320D2 L excavator. This tracked unit combines a Cat C7.1 engine, long undercarriage, and interchangeable front attachments. It is designed for contractors seeking a versatile machine that performs multiple tasks on a single job site.

The supplied images show the CAT 320D2L identification plates, steel tracks, enclosed operator cabin, and front and roof protective guards. Hydraulic lines and hoses are also visible along the boom.

Longmai Machinery supplies used construction equipment to contractors, dealers, and fleet buyers overseas. Clients can request machine details, inspection support, and shipping options before making a selection.

Long Track Chassis for Excavation and Loading

The “L” designation indicates Caterpillar’s extended undercarriage configuration. The longer track base delivers enhanced stability during excavation and material handling operations.

The standard configuration includes eight track rollers and 49 track shoes per side. Its box-section lower frame also provides rigidity and resistance to torsional loads during operation.

This setup is well-suited for foundation digging, drainage trenching, and loading from a stationary position. However, lifting capacity still depends on working radius, ground conditions, attachments, and machine configuration.

Cat C7.1 Engine and Hydraulic System

Caterpillar’s standard version is equipped with a 7.01 L Cat C7.1 diesel engine. It generates 112 kW according to ISO 14396, with a net power output of 109 kW at 1,800 rpm.

The hydraulic system features two main pumps with a combined maximum flow rate of 404 L/min. The operating pressure for work equipment reaches 35 MPa. Pilot-operated joystick controls enable the operator to manage boom, arm, bucket, and swing functions.

Automatic engine speed control reduces engine rpm during light-load or idle periods. This design helps prevent unnecessary high-speed operation, improving fuel efficiency.

Choose Front Attachments According to Job Requirements

With a 5.7 m boom and a 2.9 m arm, the standard machine can reach a maximum digging depth of approximately 6.72 m. Its horizontal reach at ground level is about 9.89 m.

This range supports deep trenching and truck loading applications. Additionally, a shorter 2.5 m arm is available as a factory option for buyers prioritizing higher arm crowding force.

Bucket selection should align with material type and task requirements. For instance, dense rock and loose soil demand different bucket designs. Hydraulic attachments also require compatible flow, pressure, piping, and mounting arrangements.

CAT 320D2 L Standard Specifications

These specifications are based on Caterpillar brochure AEHQ7776-00. Working range values are calculated with a 5.7 m boom and 2.9 m arm. Weight varies according to track shoe size and equipment configuration. Regional versions may have different engine ratings, so please verify the selected unit’s serial number, engine data plate, bucket type, and transport dimensions.

Operator Cabin and Maintenance Access

The machine in the photos is equipped with a glass cabin featuring front and roof guards. Inside, the manufacturer’s standard design includes adjustable controls and seating to help operators achieve a comfortable working position.

Maintenance accessibility is another key feature. Most routine service points are reachable from ground level. Side doors also provide access to filters, hydraulic pumps, and cooling system components.

For a used excavator, these features simplify inspection and scheduled maintenance planning. Their condition should be evaluated as part of the overall machine assessment.

Typical Applications for This Used Excavator

The CAT 320D2 L can be deployed for:

• Foundation and basement excavation

• Road and drainage construction

• Pipeline and utility trenching

• Loading soil, sand, and gravel

• Industrial site preparation
