Used CAT 336 GC Excavator for Heavy Earthmoving

The used CAT 336 GC excavator is a strong option for contractors and equipment buyers who need a large crawler excavator for daily production work.

Its size fits demanding excavation while remaining practical for road construction, quarry work, foundations, land development, and large earthmoving projects. In addition, the CAT 336 GC combines a Cat C7.1 engine with a high-capacity hydraulic system to provide steady digging and loading performance.

Hefei Longmai Construction Machinery Trading Co., Ltd. supplies used construction machinery to international buyers. Available machines can be supported with actual photos, operating videos, condition checks, export documents, and shipping arrangements.

CAT 336 GC Reference Specifications

The following values are based on a common Caterpillar 336 GC configuration. Actual specifications should be confirmed against the serial number and installed equipment of the machine being purchased.

*Values shown for a referenced boom, stick, and bucket combination. Different configurations change the working range.

36-Ton Class Capacity for Larger Jobs

The CAT 336 GC belongs to the large excavator class.

Its reference operating weight of about 36.5 tons gives the machine a stable platform for digging, lifting, and loading. Therefore, it can handle jobs where smaller excavators may require more cycles or longer working time.

The machine is well suited to contractors moving large amounts of soil each day. It can also support fleets working on infrastructure projects where digging depth, bucket capacity, and machine stability are important.

Cat C7.1 Engine and Hydraulic Power

A common CAT 336 GC specification uses the Cat C7.1 diesel engine with approximately 204 kW of net power. The hydraulic system provides up to 560 L/min of implement flow through two pumps, while maximum equipment pressure reaches 35 MPa.

This combination supports smooth boom, stick, bucket, and swing movements.

As a result, operators can maintain steady digging cycles when excavating soil, loading trucks, or preparing large sites.

For used machinery, however, specification alone is not enough. Engine response, hydraulic pressure, oil leakage, abnormal noise, and working temperature should also be checked before purchase.

Strong Reach for Excavation and Loading

Working range is one of the main reasons buyers choose a larger excavator.

With a 6.5 m reach boom and 3.2 m reach stick, Caterpillar reference data lists a maximum digging depth of about 7.53 m, a ground reach of about 11.06 m, and a loading height of about 7.07 m. The same configuration provides around 196 kN of bucket digging force.

This working envelope can help on deeper foundations, drainage projects, large trenches, and bulk loading operations.

Different boom and stick combinations are available on used machines, so buyers should confirm the actual front attachment before ordering.

Suitable for High-Volume Applications

The used CAT 336 GC crawler excavator can support a wide range of commercial projects, including:

• Highway and road construction
• Large foundation excavation
• Quarry and aggregate work
• Industrial site development
• Pipeline and drainage projects
• Bulk earthmoving
• Truck loading
• Land clearing
• Municipal infrastructure
• General civil engineering

The final machine setup can also be matched to different buckets or compatible attachments according to project needs.

What Buyers Should Inspect Before Purchase

A used heavy excavator should be evaluated as a complete working system.

First, the engine should start smoothly and run steadily. Next, buyers should check hydraulic response during boom, stick, bucket, and swing movement.

The undercarriage is also important because wear in this area can affect future maintenance cost.

A practical inspection should cover:

• Engine running condition
• Hydraulic pump response
• Boom and stick cylinders
• Bucket linkage and pins
• Swing bearing and swing motor
• Travel motors and final drives
• Track chains and track shoes
• Rollers, idlers, and sprockets
• Cab controls and display
• Electrical and lighting systems
• Structural welds and repair areas
• Fluid leakage

Actual operating videos can also help overseas buyers compare several machines before making a decision.

Better Information for Fleet and Dealer Buyers

Equipment dealers and fleet operators often need more than one photograph and a basic price.

They may need machine year, working hours, serial number, engine details, undercarriage condition, attachment type, and loading dimensions before they can approve a purchase.

For this reason, Longmai focuses on supplying used construction machinery with inspection and export support. Its range includes used excavators, loaders, bulldozers, graders, and trucks. The company also states that it works with brands including Caterpillar, Komatsu, and Hyundai.

This makes it possible for overseas buyers to source several machine types for one fleet or project.

Export and Shipping Support from Longmai

International heavy-equipment purchasing involves inspection, documentation, loading, and logistics.

Longmai provides services that include quality inspection, customs-clearance documents, international shipping coordination, spare-parts supply, and remote maintenance guidance. The company also offers equipment modifications such as GPS systems and wear-resistant components for specific project needs.

These services can help contractors and machinery dealers manage the purchasing process more efficiently when sourcing equipment from China.
