Heavy Lifting Performance of Kobelco 7150
Lifting Capacity and Radius
The Kobelco 7150 delivers a maximum lifting capacity of 200 tonnes at optimized radius points, with peak performance near the mid-radius range. The lattice boom configuration allows incremental extension, maintaining rated capacity across multiple working radii while preserving stability.
Boom Length and Section Design
The main boom, built from high-strength steel lattice sections, can be configured up to approximately 72 meters in length. Modular panel sections are fitted with robust pins and guards, enabling fast assembly on site without compromising structural integrity during long lifts.
Transport and Mobility on Site
Road Transport Dimensions
With a transport width of around 3.0 meters, the Kobelco 7150 is designed to comply with standard road regulations for oversize loads. The modular lattice boom sections are transported on flatbed trailers, allowing the crane to be moved between project sites with minimal preparation.
Setup and Relocation Time
Crawler undercarriage provides stability over uneven terrain, reducing the need for extensive ground preparation. Once positioned, the crane can be assembled and tested in a few hours, supporting tight project schedules where downtime must be minimized.
Operational Efficiency and Safety
Integrated Control Systems
Advanced monitoring and control technology optimizes load moment, amplitude, and swing, giving operators precise handling for sensitive lifts. Automated load moment indicators and safety devices respond in real time to changing conditions around the crane.
Power Management and Environmental Adaptability
The 420 kW engine can switch between performance and eco modes, reducing fuel consumption during partial-load operations. Cooling and filtration systems are designed to handle dust, heat, and variable outdoor conditions encountered in infrastructure projects.
Applications and Use Cases
Typical applications include power plant maintenance, oil and gas facility upgrades, steel structure erection, and heavy equipment installation for industrial plants. The ability to work in congested or restricted access areas makes the Kobelco 7150 suitable for urban infrastructure renewal and remote energy projects alike.

FAQ
Reader questions
What radius and load combinations are achievable with the Kobelco 7150 200 ton lattice boom crawler crane?
Rated load tables specify capacities at specific radii, with 200 tonnes available at more compact radius points and proportionally reduced ratings as the radius extends toward the maximum of approximately 60 meters.
How is transport width managed for the Kobelco 7150 on public roads?
At about 3.0 meters, the transport width aligns with standard oversize vehicle limits; project planners should verify local regulations and schedule route surveys to confirm underpasses and road geometry.
What type of boom sections are used and how are they installed on site? The lattice boom consists of modular steel panels connected with high-strength pins and safety locks, enabling rapid erection by the crane itself or with an auxiliary unit on prepared foundations. What power and operational modes are available for the Kobelco 7150?
An engine rated at 420 kW supports both high-power and eco modes, allowing operators to balance cycle time and fuel efficiency while maintaining performance for demanding lifts.
