3T Diesel-Hydraulic Crane

OUCO Diesel-Hydraulic Crane Main Hoist Working Radius from 8.5m to 38.5m, Auxiliary Hoist Working Radius: 9.5m to 40m, Slewing Angle: >360°, with Lattice Boom and CCS Certified.

• Self-Sufficient, Diesel-Powered Performance

The OUCO diesel-hydraulic crane is engineered for independent offshore operation, featuring a self-contained diesel engine system that eliminates reliance on vessel generators or external electrical infrastructure. This autonomous power solution allows for true "plug-and-play" lifting capability—ideal for vessels with limited onboard power or for use in remote coastal and offshore environments.

• High Torque and Rapid Response for Heavy-Duty Tasks

Designed for precision and strength, this crane delivers exceptional torque at low RPM, making it perfect for heavy-load lifting, barge operations, or offshore hoisting. Its lattice boom structure balances reduced weight with structural strength, while integrated counterweights ensure deck stability, even during dynamic lifting tasks.

The direct hydraulic drive system ensures instant response to commands, allowing operators to execute frequent start-stop cycles and rapid load adjustments with high accuracy. Whether it’s cargo transfer, offshore construction, or emergency salvage, this crane boosts your operational efficiency.

• Adaptability in Harsh Marine Environments

Built for extreme conditions, the OUCO diesel-hydraulic crane thrives in high-temperature, high-humidity, dusty, or saline environments. Unlike electric cranes, it remains unaffected by voltage drops or power fluctuations, offering stable performance in rugged marine conditions.

The diesel engine also ensures zero electromagnetic interference, making this crane suitable for use near radar systems, navigation equipment, and sensitive electronics, where operational safety is critical.

• Cost-Effective, Long-Term Operation

OUCO's diesel-hydraulic solution supports continuous lifting operations without power restrictions. Thanks to its compatibility with widely available diesel fuel, this crane is a smart choice for operations in off-grid locations, international ports, and areas with unreliable electricity access.

Maintenance is simplified with proven diesel engine technology, offering lower lifecycle costs and reducing downtime when compared to electric cranes with complex inverter systems or cable layouts.

• Trusted Worldwide – Proven in Offshore and Floating Applications

OUCO’s diesel-hydraulic cranes are widely used across Asia, Southeast Coastal China, the Middle East, and South America. Their rugged, mobile, and efficient design supports a variety of offshore missions—from floating dock operations, pile driving, and material handling to emergency marine recovery tasks.

Our products are certified by CCS and built in accordance with international marine standards, delivering the strength, flexibility, and safety your offshore operations demand.

Looking for a mobile, durable, and efficient crane that works where electric cranes can’t? OUCO’s diesel-hydraulic crane is your best choice.
