Plan your next equipment purchase with the tasks ahead. The CAT 320D2 L is a crawler excavator for digging, loading, and site preparation. Its long track base and reach-boom layout make it suitable for contractors handling mixed earthwork operations.
Longmai Machinery supplies used equipment to construction companies, machinery dealers, rental firms, and project buyers. Through our used construction machinery supply service, customers can arrange machine selection, inspection, and overseas delivery.
The photos provided show 320D2 L model markings, a digging bucket, steel tracks, and an enclosed cab. They also show a front cab grille, roof guard, work lights, mirrors, and rear-mounted beacons.
One Excavator for Multiple Stages of Site Work
A construction fleet requires equipment that matches both the work and the site conditions. The CAT 320D2 L can support excavation before foundations, trenching during utility installation, and loading material as the project progresses.
| Project task |
What buyers should match |
| Foundation excavation |
Digging depth, ground conditions, and bucket width |
| Drainage trenches |
Stick reach, trench size, and spoil placement |
| Truck loading |
Loading height, truck access, and material density |
| Land development |
Ground support, crawler condition, and attachment choice |
| General earthmoving |
Expected workload, machine condition, and transport limits |
Therefore, please share your main task when requesting a machine quotation. This helps Longmai compare suitable units and attachment configurations.
Caterpillar Design Features
The manufacturer’s reference design combines a reinforced reach boom with a long crawler undercarriage. The lower frame uses a box-section structure to resist torsional loads. Meanwhile, the extended track base provides stable support during digging and loading.
Pilot-operated joysticks control the front equipment, swing, and travel functions. In addition, adjustable seating and control consoles help operators find a comfortable working position.
Most routine service points are accessible from ground level. Side service doors also provide access to key filters, hydraulic components, and cooling equipment. As a result, maintenance teams can plan routine inspections more easily.

Hydraulic Power and Attachment Options
The reference hydraulic system uses two main pumps. Together, they supply the boom, stick, bucket, swing, and travel functions.
However, an attachment requires more than sufficient machine size. A breaker, grapple, or compactor must match the flow and pressure of the installed circuit. Tool weight, mounting dimensions, return lines, and any case-drain requirements also matter.
For bucket work, choose capacity based on material density. A bucket designed for loose soil may not be suitable for the same volume of dense aggregate. Therefore, please request the included bucket’s capacity, width, and condition in the quotation.
Inspect the Equipment Shown in the Photos
The pictured cab has a reinforced front grille and an overhead guard. Their mounts, condition, and effect on visibility should be checked during inspection. Any required protection rating must be verified through supporting documents.
The photos also show covers around parts of the boom cylinders and exposed hydraulic piping. Inspect these areas for damage, leaks, and hidden wear.
Surface rust is visible on the track shoes. Remaining crawler life requires closer inspection of the chains, rollers, idlers, sprockets, and adjusters.
Documents to Request Before Ordering
A useful machine review should include:
-
Serial number, production year, and recorded hours
-
Cold-start footage and a warm operating test
-
Engine response under hydraulic load
-
Digging, swing, and travel demonstrations
-
Cylinder rods, hoses, pins, and bushings
-
Boom and frame repairs, where present
-
Cab controls, lights, alarms, and interlocks
-
Available maintenance and repair records
