Used CAT 320 GC Excavator for Roadwork and Utility Projects

Move from trench excavation to truck loading with a used CAT 320 GC excavator from Longmai Machinery. This crawler model suits contractors and fleet buyers who need a machine for general digging, backfilling, and material handling.

The pictured unit carries clear 320 GC markings. It has a toothed digging bucket, steel tracks, an enclosed cab, a full front cab guard, mirrors, and work lights. Inside, the photos show joystick controls, travel levers, a display, and a seat with armrests.

Longmai Machinery supplies used construction machinery for business buyers. Machine details, inspection options, and export arrangements can be discussed before purchase.

Plan Digging and Loading Around One Machine

The CAT 320 GC can support several stages of a groundworks project. First, the operator can excavate trenches or remove soil. Next, the bucket can load loose material into trucks. Later, the machine can return for backfilling and rough shaping.

Typical applications include:

• Road drainage and culvert excavation

• Building foundations and service trenches

• Residential and industrial site development

• Soil, sand, and gravel loading

• Landscape earthworks

• Contractor and rental fleet work

Daily output depends on soil conditions, bucket choice, hauling capacity, and machine condition. Therefore, share your main tasks and required digging depth when requesting an offer.

Caterpillar Engine and Hydraulic Design

Caterpillar’s published 320 GC configurations use the Cat C4.4 engine. However, power ratings differ between production periods and markets.

The earlier reference version below lists 90 kW of net power and a 4.4 L displacement. Its hydraulic system has a maximum main flow of 442 L/min.

Manufacturer equipment lists also describe selectable power modes and automatic engine speed control. These features help adjust engine operation to the task. Their presence and function should be checked on the selected machine.

Reference Technical Specifications

These figures follow an earlier published CAT 320 GC configuration. They provide a comparison point and do not establish the pictured unit’s exact specification.

Confirm the serial number, engine plate, boom, stick, bucket, and track setup before ordering. Actual weight and transport dimensions should also be checked for the shipping plan.

Choose the Bucket for the Material

The supplied photos show a bucket with digging teeth. This arrangement suits excavation and loading, although the best bucket size depends on material density and site conditions.

For example, loose soil and dense gravel place different loads on the machine. Consequently, bucket selection should consider both capacity and weight.

Buyers should confirm the included bucket’s width, capacity, teeth, side plates, and pin dimensions. In addition, inspect the linkage and bushes for play.

Pipework is visible along the digging equipment. Before fitting a breaker or another powered tool, check the installed circuit, flow, pressure, and return-line requirements.

Cab Layout and Access

The pictured cab has large glazed panels and a full front grid guard. The interior places the joysticks beside the seat, while travel levers and pedals sit ahead of the operator.

During inspection, check the display, control response, seat adjustment, door latch, wiper, lights, and ventilation. Any air-conditioning system should also be tested.

The front guard’s mounts and its effect on visibility deserve attention. Its appearance alone does not confirm a particular protection rating.

Check Wear Where It Matters

Close-up photos show surface rust on parts of the steel track shoes. Remaining undercarriage life should therefore be assessed through measurements and an operating inspection.

Request checks of the track chains, rollers, idlers, sprockets, and adjusters. Also review the swing bearing, final drives, cylinder rods, hoses, and boom joints.

A useful machine review should include:

• Cold starting and engine response under load

• Warm hydraulic operation

• Combined boom, stick, bucket, and swing movements

• Forward and reverse travel

• Fluid leaks and unusual noise

• Structural repairs and available service records

Recorded hours should be checked against available records. Our used machinery buying guide explains further points to review.

Equipment Sourcing and Overseas Delivery

Longmai Machinery works with contractors, equipment traders, rental firms, and project buyers. Inspection coordination, export documents, shipping support, and parts sourcing can be discussed for the selected unit.

Furthermore, cleaning, servicing, agreed repairs, and attachment supply should be listed clearly in the quotation. Transport arrangements depend on confirmed dimensions, weight, destination, and carrier limits.
