Used CAT 320D2 L Excavator for Trenching and Truck Loading

A used CAT 320D2 L excavator offers contractors a reliable option for trench digging, soil moving, and haul truck loading. Its long undercarriage supports a reach-boom design well-suited for general construction.

The photos provided identify this unit as a 320D2 L. They show a bucket, steel crawler tracks, an enclosed cab, a front grille, and an overhead guard. Hydraulic lines, work lights, mirrors, cylinder covers, and warning beacons are also visible.

Longmai Machinery helps business buyers source used construction equipment with machine information, inspection coordination, and export support. Each offer should describe the selected unit and its included equipment.

CAT 320D2 L Specifications at a Glance

The following figures come from Caterpillar’s published AME/CIS reference configuration. They provide a model comparison point and do not establish the pictured unit’s exact regional specification.

Working ranges use the 5.7 m boom and 2.9 m stick. Weight depends on equipment and track shoes. Confirm the serial number, engine rating, boom, stick, bucket, and measured shipping dimensions before ordering.

Plan the Digging and Loading Cycle

The reference reach allows the operator to cover a broad area from one position. Meanwhile, the loading height helps buyers assess truck access and body clearance.

However, maximum reach is only one part of the work plan. Truck position, swing angle, soil type, and bucket fill also affect each cycle. Therefore, share the expected material and truck size when discussing machine selection.

For trenching, confirm the required depth and bucket width. For repeated loading, check bucket capacity against material density and the excavator’s limits.

Hydraulic Control for Mixed Tasks

Caterpillar’s reference design combines two main hydraulic pumps with pilot-operated controls. This arrangement supports coordinated boom, stick, bucket, and swing movement.

In addition, boom and stick regeneration circuits reuse hydraulic flow during selected movements. The design also includes cylinder cushioning to limit shocks near stroke ends.

Hydraulic tools require separate checks. A breaker, grapple, or compactor must match the installed circuit’s flow, pressure, return arrangement, and mounting dimensions. Visible pipework does not confirm that every required circuit is present.

Long Crawler Base and Enclosed Cab

The “L” version uses a long undercarriage to provide stable working support. Its reference crawler layout includes eight track rollers and 49 shoes per side.

The pictured cab has a front grille and roof guard. Buyers should assess their mounts, condition, and effect on visibility. Any required protection rating must be verified through supporting documents.

Inside, Caterpillar’s reference design provides adjustable seating and control consoles. During inspection, check the installed controls, seat belt, windows, door latches, warning indicators, and ventilation equipment.

What to Review on the Pictured Machine

The photos show wear marks on the bucket and surface rust on the track shoes. These details support a closer condition review, but they do not establish remaining component life.

Request a cold-start demonstration followed by operation at working temperature. The review should cover:

• Engine starting, exhaust, cooling, and leaks

• Hydraulic response under load

• Boom, stick, and bucket joints

• Cylinder rods, seals, and hoses

• Swing bearing play and unusual noise

• Track chains, rollers, idlers, and sprockets

• Travel motors and final drives

• Previous welding or structural repairs

Furthermore, ask for available service records and disclosed repairs. Our used construction machinery buying guide explains further checks for overseas purchases.
