Used CAT 320 GC Excavator for Everyday Earthmoving

Keep excavation, material loading, and site preparation moving with a used CAT 320 GC excavator. This Caterpillar crawler model suits contractors who need a machine for varied daily work.

The supplied photos show 320 GC model markings, a toothed digging bucket, steel tracks, and an enclosed cab. They also show a lower front cab guard, an overhead guard, mirrors, work lights, handrails, and covers around parts of the hydraulic cylinders.

Longmai Machinery supplies used construction machinery to contractors, equipment dealers, rental firms, and fleet buyers. Customers can discuss machine condition, inspection requirements, preparation work, and overseas delivery.

Power Management for Changing Workloads

The CAT 320 GC design includes selectable power modes and automatic engine speed control. These features allow engine operation to suit different work demands. In addition, automatic idle shutdown can limit unnecessary engine running when enabled.

For a used machine, confirm that the installed controls and operating modes work correctly. Fuel use will depend on material, workload, operator technique, and machine condition.

The specification table below follows an earlier 90 kW Cat C4.4 configuration. Other 320 GC versions have different power ratings, so the selected unit’s engine plate must be checked.

Reference Technical Specifications

The following figures come from an earlier 320 GC specification document distributed by Cat dealer Avesco. They describe one published configuration and are not verified measurements for the pictured machine.

Regional versions, production changes, buckets, track shoes, and other equipment can alter these figures. Therefore, confirm the serial number, engine rating, installed attachments, actual weight, and transport dimensions before ordering.

Hydraulic Design for Digging and Loading

Caterpillar’s published 320 GC equipment includes an electronic main control valve and main pump. Boom and stick regeneration circuits reuse hydraulic flow during selected movements. Meanwhile, automatic two-speed travel helps manage movement between work positions.

These design features support a mixed workload. However, hydraulic condition should be assessed with the machine at working temperature.

Buyers should review combined boom, stick, bucket, and swing movements. A demonstration should also include travel in both directions and checks for leaks, unusual noise, and excessive drift.

Match the Bucket to the Material

A toothed bucket is visible in the photos. Its actual capacity, width, wear condition, and inclusion in the sale should be stated in the quotation.

Bucket selection affects both digging and loading. For example, loose soil and dense aggregate place different demands on the excavator. Consequently, bucket size should match material density and the machine’s working limits.

Breakers, grapples, compactors, and quick couplers may also be considered after compatibility checks. Confirm mounting dimensions, hydraulic flow, pressure, return lines, and tool weight before ordering.

Cab Features and Service Access

The pictured cab has large windows, a front wiper, side mirrors, and a roof guard. The interior photo shows a seat with headrest and armrests, together with controls beside the seat.

Check visibility, seat adjustment, control response, door latches, warning indicators, and ventilation equipment during inspection. Furthermore, any required cab or guard protection rating needs supporting documentation.

The exterior photos also show access steps, handrails, and side service panels. Their condition matters when planning daily checks and maintenance.

Suitable Commercial Applications

This used excavator can be considered for:

• General building-site excavation

• Foundation and footing preparation

• Drainage and utility trenches

• Roadside earthworks

• Soil and gravel loading

• Industrial site development

• Rental fleet expansion

Condition Review Before Purchase

The photos show surface rust on the track shoes and wear marks on the bucket. Remaining component life requires a closer inspection.

Request the production year, serial number, recorded hours, available maintenance records, and details of previous repairs. Next, arrange a cold-start demonstration and a warm operating test.

Inspection should cover the engine, hydraulic system, cylinders, boom, stick, pin joints, swing bearing, final drives, and crawler components. Our used construction machinery buying guide explains further purchasing checks.

Export Supply and Order Preparation

Longmai Machinery 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 also be discussed. Moreover, shipping plans should use confirmed dimensions and weight.

The purchase terms should identify the supplied bucket, preparation work, inspection arrangements, loading responsibilities, delivery terms, and expected dispatch schedule.
