Kobelco 7055-1 crawler crane (1993 model), 55-ton lifting capacity, 51.8 m boom length, suitable for bridge construction, factories, and industrial foundation works.
Heavy-duty crawler cranes are indispensable equipment for large-scale projects such as overpasses, bored pile construction, factories, and steel structures. In the 55-ton class, the Kobelco 7055-1 crawler crane is highly regarded by contractors for its durability, flexible operation, and outstanding safety. In particular, this 1993 model currently offered by Hanoi Vietnam still maintains stable performance, a robust configuration, and is ready for immediate deployment on site.
In this article, Hanoi Vietnam provides an in-depth analysis of the technical specifications, real-world performance, operating costs, and comparisons with other construction cranes to help engineers and investors make well-informed decisions.
Overview of the technical configuration of the Kobelco 7055-1 crawler crane
The Kobelco 7055-1 is a representative model in the 55-ton hydraulic crawler crane segment. It is designed for job sites requiring high lifting capacity and a wide working radius, making it especially suitable for foundation works, factories, overpasses, and heavy steel structure installation.
The crane features a powerful engine, precise hydraulic control system, and highly flexible boom configurations to meet demanding technical requirements.
Key specifications include:
- Maximum lifting capacity: 55 tons at a 3.7 m radius
- Main boom length: Up to 51.8 m
- Fixed jib combinations: 42.7 m + 12.2 m or 39.6 m + 18.3 m
- Tower jib configuration: 42.4 m + 29.0 m
- Engine output: 159 kW, compliant with NRMM Stage IIIA and EPA Tier III emission standards
Overall, this crane offers a strong configuration within its price range, optimizing investment costs compared to newer models that do not necessarily deliver superior performance.
Operational advantages of the Kobelco 7055-1 in real construction projects
The strength of the Kobelco 7055-1 lies not only in its specifications but also in its smooth operation, stability, and high safety level throughout operation. With a 159 kW engine and a responsive hydraulic control system, the crane handles heavy lifting, slewing, and boom movements in confined spaces with precision and reliability.
Notable features that enhance productivity include:
- Hydraulic control levers directly linked to control valves: Enable fast, smooth, and jerk-free operation.
- Multifunction LMI display: Shows load, working radius, boom angle, and other parameters in real time, minimizing operational errors.
- Flexible boom configurations: Suitable for various working heights and radii.
- Two-stage overload protection system: Automatically limits movements when safety thresholds are exceeded, preventing overturning or overload.
In practice, many contractors using this model on major projects—such as industrial plants, bridges, and large-scale construction sites—highly appreciate its stability and reasonable operating costs.
Powerful engine and advanced emission standards
One of the major advantages of the Kobelco 7055-1 is its high-power diesel engine that remains fuel-efficient while meeting advanced emission standards. With a rated output of 159 kW, the engine enables continuous heavy-duty operation without overheating or power loss.
The crane complies with NRMM Stage IIIA (Europe) and US EPA Tier III standards, which is increasingly important as many projects—especially in urban or residential areas—require stricter environmental compliance.
Safety features: a top priority on every job site
A crawler crane must be not only powerful but also safe. The Kobelco 7055-1 is equipped with multiple layers of safety protection to ensure maximum safety for operators and surrounding work areas:
- Emergency stop switch: Automatically shuts down the crane in case of emergencies
- Load limiting system: Prevents overload or exceeding allowable boom radius
- Free-fall interlock system: Prevents unintended sudden load release
- Electronic alarms and indicator lights: Keep operators fully informed of crane status
Thanks to these features, the crane maintains high safety levels even during night shifts or adverse weather conditions.
