Used CAT 349 Excavator for High-Output Earthmoving

The used CAT 349 excavator is built for projects where production volume, digging force, and machine stability are key purchasing factors.

With a Cat C13 engine and a working weight close to the 50-ton class, the CAT 349 is suited to large earthmoving jobs, quarry operations, road construction, industrial projects, and heavy truck loading.

For contractors, equipment dealers, rental companies, and fleet owners, this model offers a useful step up from mid-size excavators when a project requires more bucket force and higher daily output.

Hefei Longmai Construction Machinery Trading Co., Ltd. supplies used construction machinery to overseas buyers and supports machine inspection, export preparation, international shipping, spare parts, and remote maintenance.

CAT 349 Reference Specifications

The following specifications are based on a Caterpillar 349 configuration with a 6.9 m Reach Boom, R3.35TB stick, and 1.90 m³ Heavy Duty bucket. Actual specifications should be confirmed according to the serial number and equipment fitted to each machine.

Cat C13 Power for Large Excavation Jobs

The CAT 349 uses a 12.5-liter Cat C13 diesel engine. In the referenced configuration, net power reaches approximately 316 kW.

This power level supports large hydraulic demand during deep digging, loading, and repeated production cycles. Therefore, the machine can work effectively on jobs where smaller excavators may need more passes to move the same amount of material.

For used-machine procurement, however, engine condition remains more important than the rated figure alone.

Buyers should check cold starting, smoke, operating temperature, abnormal noise, oil leakage, and power response before approving a unit.

779 L/min Hydraulic Flow for Productive Cycles

Large excavators depend heavily on hydraulic capacity.

The CAT 349 reference system provides up to 779 L/min of implement flow from two main pumps. Maximum equipment pressure is approximately 35 MPa.

This high hydraulic output supports fast and controlled boom, stick, bucket, and swing movements.

For projects involving continuous truck loading, this can help maintain steady cycle times. It also provides the hydraulic capacity needed for compatible heavy-duty attachments.

When inspecting a used unit, buyers should review pump response, cylinder operation, hose condition, seals, hydraulic temperature, and visible leakage.

Strong Digging Force for Hard Material

The referenced CAT 349 configuration delivers approximately 268 kN of ISO bucket digging force and 199 kN of stick force.

This level of breakout force makes the excavator useful for compact soil, hard ground, large excavation areas, and quarry support.

The machine can also work with different bucket sizes according to material density and project needs.

For example, a contractor moving loose soil may prefer a larger bucket, while harder material may require a smaller heavy-duty or severe-duty bucket.

Working Range for Deep and Wide Excavation

With the referenced boom and stick combination, the CAT 349 provides:

• Maximum digging depth of about 7.66 m
• Maximum ground reach of about 11.73 m
• Maximum cutting height of about 10.82 m
• Maximum loading height of about 7.43 m

These dimensions give contractors flexibility on foundation excavation, deep trenches, large cuts, and high-sided truck loading.

Other stick and bucket combinations can change these values, so the actual front attachment should be confirmed before purchase.

A Practical Match for High-Capacity Fleets

A 349-class excavator is often purchased as part of a larger production system rather than as a standalone machine.

It can be paired with suitable dump trucks, crushers, loaders, and other site equipment to improve material flow.

Typical applications include:

• Quarry excavation
• Mining support
• Highway construction
• Large foundation projects
• Bulk earthmoving
• Industrial site development
• Large drainage works
• Pipeline projects
• Rock and soil loading
• Land development

For fleet buyers, matching bucket capacity with haul-truck size can also reduce waiting time and improve overall site productivity.

Undercarriage Condition Matters on a Used CAT 349

The CAT 349 carries substantial machine weight through its crawler system. Therefore, undercarriage condition is an important part of any used-equipment purchase.

Buyers should inspect the track shoes, chains, rollers, carrier rollers, idlers, sprockets, and track tension.

The referenced CAT specification uses 52 track shoes per side, nine track rollers, and two carrier rollers per side. However, configuration can vary.

Wear in these components can create a significant future maintenance cost, so detailed photos and physical inspection are valuable before shipment.

Inspection Information for Professional Buyers

Professional buyers usually need more than a machine year and price.

A useful CAT 349 inspection should include:

• Serial number verification
• Engine start and running test
• Hydraulic movement test
• Boom and stick inspection
• Bucket and linkage wear
• Swing system condition
• Final drive and travel test
• Undercarriage wear
• Cab and control functions
• Electrical system
• Fluid leakage check
• Structural repair inspection

Operating videos can also show boom lifting, digging movement, swing, travel, and engine response before the machine is shipped.
