Our specialized yard conducts rigorous technical evaluations, hydraulic pressure load testing, and structural inspections on every unit to guarantee immediate deployment upon job site arrival.

Advanced Hydraulic Engineering and Structural Capabilities

Every second-hand earthmoving unit in our equipment inventory undergoes comprehensive mechanical verification by certified heavy equipment specialists to ensure strict compliance with original factory working standards.

Caterpillar C9 ACERT High-Torque Powertrain

At the core of this 33.75-ton crawler excavator is the original Caterpillar C9 ACERT turbocharged diesel engine. Built in a robust 6-cylinder, water-cooled configuration with an 8.8L displacement, this engine produces a rated power output of 200 kW at 1,900 rpm. Designed specifically for long-term endurance under continuous heavy-duty cycles, the ACERT powertrain generates steady torque output at efficient engine speeds. This engineering design minimizes hourly fuel burn while maintaining consistent hydraulic pump pressure across high-resistance digging applications.

Cat Main Pump and Distribution Valve System

The hydraulic architecture integrates genuine Cat main pumps and precision distribution valves, ensuring exceptionally smooth multi-function coordination during combined swinging, boom lifting, and bucket operations. The precision-engineered hydraulic system develops a powerful bucket digging force of 222 kN and a stick digging force of 146 kN. Paired with a standard 1.4 m³ heavy-duty reinforced bucket, the machine delivers rapid trenching, material loading, and quarrying capabilities across hard rock, compacted subgrade, and loose aggregate ground conditions.

Reinforced Undercarriage and Track Assembly

Constructed on a heavy-duty steel crawler undercarriage, the machine features a variable travel speed range of 3.5 to 5.5 km/h and a rapid swing rotation speed of 10 rpm for optimized cycle times. With a 35°/70° gradeability rating and a generous 620L capacity fuel tank, this tracked excavator maintains firm ground traction, stability, and extended daily operational uptime on steep slopes, unpaved earthworks, and challenging mining yards.

Primary Industrial Application Scenarios

Deep Foundation Trenching and Municipal Works

With a maximum excavation depth of 7,390 mm and a maximum vertical digging depth of 5,830 mm, this unit excels in deep foundation footing, basement excavation, and large-scale municipal utility pipeline installations. Responsive pilot joystick controls give operators refined handling when trimming trench walls cleanly, reducing manual labor and post-excavation site cleanup work.

Mass Earthmoving and Heavy Truck Loading

Featuring a maximum excavation height of 10,240 mm and an unloading height of 7,200 mm, the equipment easily clears high-sided commercial haul trucks and heavy aggregate dump trailers. The 1.4 m³ bucket volume paired with smooth 10 rpm swing rotation speeds ensures rapid truck turnaround times on large-scale commercial earthmoving sites.

Mining, Quarrying, and Heavy Demolition

The 222 kN bucket breakout force provides necessary digging power when cutting into compacted subgrade, crushed stone, and road bed demolition projects. The heavy-duty track assembly absorbs continuous shock loads when operating hydraulic breakers, rock rippers, or processing concrete debris during site clearing operations.

Customization, Maintenance, and Export Logistics Support

We offer comprehensive pre-delivery machine preparation to match your specific job site requirements and regional customs import documentation standards.

Hydraulic System Recalibration: Technicians perform full system pressure checks, calibrate distribution valve spools, and renew main hydraulic seals to ensure original cycle speeds and prevent pressure drop under load.
Engine Servicing and Preventive Care: Engine oil, primary fuel filters, air filters, and cooling fluid are renewed, accompanied by complete valve adjustment and fluid sample testing to guarantee long-term operational reliability.
Auxiliary Line Retrofitting: Optional dual-way auxiliary hydraulic piping can be installed on the 6,500 mm boom and 3,200 mm arm to power hydraulic breakers, concrete pulverizers, or quick-attach couplers.
Export Logistics Coordination: Machines are professionally washed, secured, and loaded for ocean transport using Flat Rack containers or Roll-on/Roll-off (RoRo) vessels, complete with commercial invoices, packing lists, and original bill of lading documentation.

Frequently Asked Questions (FAQ)

How is the hydraulic main pump tested before shipment?

Our technicians connect diagnostic pressure gauges directly to the Cat main pumps to test working relief pressures under full hydraulic load conditions. We verify that flow rates and distribution valve spools respond without hydraulic lag or thermal pressure drop.

Can the machine be customized with additional hydraulic piping for attachments?

Yes, our yard technicians can install extra auxiliary hydraulic lines on the boom and arm. This allows the excavator to power hydraulic breakers, concrete pulverizers, or tilt-rotators based on your specific project demands.

What export documentation is provided for customs clearance?

Every order includes a full commercial invoice, detailed packing list, original Bill of Lading, and pre-shipment technical inspection report to facilitate smooth customs processing at destination ports.

What are the exact shipping dimensions for freight transport planning?

The overall transport dimensions are 11,150 mm in length, 3,190 mm in width, and 3,340 mm in height, with an operating weight of 33,750 kg. This allows for standard flat-rack containerization or RoRo ocean freight transport.

What payment terms apply to heavy machinery purchases?

We process orders via standard Wire Transfer (T/T). Orders are confirmed upon receipt of a commercial deposit to initiate inspection and freight preparation, with the balance settled upon presentation of shipping documents.
