This Caterpillar 320D2 L is built for digging basements, laying drainage lines, and loading excavated earth with a used CAT 320D2 L excavator. Its long crawler base and reach-boom layout make it a practical choice for varied construction tasks.
This Caterpillar is available. The photos show clear 320D2 L markings, a fitted bucket, steel tracks, an enclosed cab, and front and roof guards. Work lights, mirrors, hydraulic pipework, cylinder covers, and rear beacons are also visible.
Longmai Machinery supplies used construction machinery to contractors, equipment traders, rental businesses, and fleet owners. Buyers can discuss the selected machine’s condition, preparation needs, and delivery terms before ordering.
Digging Reach That Supports Site Planning
Working range affects where an excavator can stand and how often it must move. Caterpillar’s published configuration with a 5.7 m boom and 2.9 m stick reaches approximately 9.89 m at ground level. Maximum digging depth is about 6.72 m.
This arrangement suits trenching and foundation work. Meanwhile, a reference loading height of 6.49 m provides a useful starting point when planning truck positions.
Actual output also depends on soil conditions, bucket choice, operator skill, and truck access. Therefore, buyers should share their required digging depth and loading plan when requesting a quotation.
Engine and Hydraulic System
The published reference version uses a Cat C7.1 engine with a displacement of 7.01 L. Caterpillar lists 112 kW of engine power under ISO 14396 and 109 kW of net power at 1,800 rpm.
Two hydraulic pumps provide a combined maximum flow of 404 L/min. In addition, the reference equipment pressure reaches 35 MPa.
The manufacturer’s design places the pumps, valves, and hydraulic tank close together to shorten connecting lines. Pilot controls help the operator manage digging and swing movements. Automatic engine speed control also lowers engine speed during light-load conditions.
These are model reference features. The installed engine, controls, and hydraulic performance require confirmation on the selected unit.

The table follows Caterpillar’s AME/CIS brochure AEHQ7776-00. Working ranges use the 5.7 m boom and 2.9 m stick. The pictured machine’s regional version is unconfirmed; production changes and installed equipment may affect the figures. Verify the serial plate, engine plate, attachments, and transport measurements before purchase.
Long Undercarriage and Structural Support
The “L” version has a long undercarriage designed to provide stable support during digging and loading. Caterpillar’s reference layout uses eight track rollers and 49 track shoes on each side.
Furthermore, the box-section lower frame helps resist twisting forces. The boom and stick use reinforced steel structures for excavation loads.
For equipment buyers, remaining crawler life is an important cost factor. The photos show surface rust on the track shoes, while chain, roller, and sprocket wear needs a closer inspection.
Bucket and Work-Tool Selection
A bucket is fitted in the supplied photos. Its capacity, width, wear condition, and inclusion in the sale should appear in the quotation.
For soil loading, bucket size must suit material density and the machine’s limits. For trench work, bucket width should match the required excavation profile.
Other tools may be considered after compatibility checks. These can include breakers, grapples, compactors, and quick couplers. However, visible pipework alone does not confirm a complete auxiliary circuit. Check hydraulic flow, pressure, return arrangements, mounting dimensions, and tool weight first.
Applications for Contractors and Fleet Buyers
This used excavator can be considered for:
-
Building foundations and basement excavation
-
Roadside drainage and culvert work
-
Water and utility pipeline trenches
-
Industrial site development
-
Soil, sand, and gravel loading
-
Suitable land-clearing projects
For land-development purchases, our guide to choosing used excavator tonnage helps buyers relate machine size to the task.
Machine Review and Export Preparation
Start with the machine’s identity and records. Request its serial number, production year, recorded hours, and available maintenance history. Next, arrange a cold-start demonstration and a warm operating test.
Inspection should cover engine response, hydraulic leaks, cylinder rods, pin joints, swing play, travel performance, and structural repairs. Cab guards, warning devices, controls, and access points also need checks.
Our used machinery buying guide provides further purchasing guidance.
Longmai supports overseas buyers with inspection coordination, export documents, shipping arrangements, spare-parts supply, and remote maintenance guidance. Cleaning, servicing, agreed repairs, and attachment sourcing can be discussed for the selected machine.
Frequently Asked Questions
Can the photos confirm the machine’s year and hours?
No. Request the serial plate, hour-meter reading, and supporting records.
Does the cab guard confirm a protection rating?
The photos show guards, but any required rating must be checked through identification marks and documents.
How is international shipping planned?
The shipping method depends on measured dimensions, weight, destination, and carrier limits.
