Used CAT 320D2 L Excavator for Road and Drainage Teams
Product Information
Road and drainage crews often need one excavator to dig, load, and prepare ground as work moves along a site. The CAT 320D2 L offers a long crawler base and a reach-boom layout that buyers can consider for this mixed workload.
Longmai Machinery supplies used equipment to contractors, machinery dealers, rental companies, and fleet owners. We help buyers review machine details and discuss inspection, preparation, and export arrangements.
The supplied photos show 320D2 L model markings, a toothed bucket, steel tracks, an enclosed cab, front and roof guards, mirrors, work lights, and rear beacons. An interior view also shows the seat, armrests, and hand controls.
Caterpillar Engineering for Earthmoving
Caterpillar’s reference design combines a reinforced digging structure with a box-section lower frame. The long undercarriage provides stable support during excavation and loading.
The published engine configuration uses a Cat C7.1 diesel engine. Meanwhile, two main hydraulic pumps supply the working equipment, swing, and travel systems.
This combination supports general earthmoving tasks. However, a used machine’s actual performance depends on its condition, maintenance, and installed equipment. Therefore, model data should be reviewed alongside operating tests and service records.

Working ranges and digging forces use the 5.7 m boom and 2.9 m stick. The pictured unit’s exact regional version is unconfirmed. Check its serial plate, engine plate, attachments, track shoes, and measured transport dimensions before ordering.
Working Range for Linear Projects
The reference digging range suits drainage channels, utility trenches, and foundation work. Its reach also helps operators place spoil or load nearby trucks from a suitable working position.
For road projects, machine selection should account for traffic access, available working width, and ground support. In addition, bucket width should match the trench profile.
Buyers comparing configurations can review our used CAT 320D2 excavator. Compare the undercarriage and installed equipment as well as the sale price.
Bucket and Hydraulic Tool Options
The pictured excavator has a toothed bucket. Confirm its capacity, width, tooth condition, and inclusion in the quotation.
A suitable bucket depends on the material being moved. Loose soil, clay, gravel, and dense aggregate place different loads on the machine. Consequently, a larger bucket is not always the right choice.
Powered tools may expand the machine’s role after compatibility checks. Possible options include breakers, grapples, and compactors. Check hydraulic flow, pressure, return lines, mounting dimensions, and tool weight before selecting an attachment.
Cab Layout and Daily Service Access
The enclosed cab provides a sheltered operator space. The photos show front and overhead guards, but any required protection rating needs supporting documentation.
Caterpillar’s reference cab design includes adjustable seating and control consoles. During inspection, check the installed controls, seat belt, windows, door latches, warning systems, and ventilation equipment.
Furthermore, many routine service points on the reference model are accessible from ground level. This layout helps maintenance staff reach filters and check key components.

Condition Checks Before Purchase
Start by confirming the production year, serial number, recorded hours, and available maintenance history. Next, request a cold-start demonstration and operation at working temperature.
Inspection should cover engine response, hydraulic leaks, cylinder rods, boom and stick joints, swing play, and travel performance. The bucket, track chains, rollers, idlers, and sprockets also need close review.
Ask for details of previous structural repairs and major component work. Our used construction machinery buying guide explains further purchasing checks.
Preparation and Overseas Delivery
Longmai Machinery supports buyers with inspection coordination, export documents, international shipping arrangements, spare-parts supply, and remote maintenance guidance.
Cleaning, servicing, agreed repairs, and attachment sourcing can also be discussed. Each item should be recorded in the purchase terms.
Shipping plans depend on confirmed dimensions, weight, destination, and carrier limits. Therefore, agree on the loading method, included attachments, delivery terms, and expected dispatch schedule before shipment.
