Project Background: Demand-Driven Equipment Upgrading
As a major domestic hub for container and bulk cargo handling in China, this port's business scope covers large-scale construction machinery, wind power equipment modules, precast components, and traditional bulk commodities. The project faced the following core challenges in its preliminary phase:
- Bottlenecks in Heavy Equipment Handling: Existing equipment was unable to efficiently handle large cargo with a unit weight of 60–80 tons.
- Requirements for Extensive Operating Coverage: The designated terminal area of the port spans hundreds of meters in length. These necessitating cranes can move flexibly and cover an operating radius of at least 80 meters.
- Space and Foundation Constraints: Fixed large-scale cranes involve high costs and occupy valuable shoreline resources.
- Demand for Precise Positioning: The handling of large and precision equipment requires cranes to have extremely high stability and micro-motion performance.
Solution: 80ton-80M Rail-mounted Mobile Portal Jib Crane---YFMMPC8080
To address the aforementioned operational bottlenecks and in light of the port's existing heavy-duty rails with a 16-meter gauge, the client ultimately selected the YFMMPC8080 Rail-mounted Mobile Portal Jib Crane (rated lifting capacity: 80 tons; maximum working radius: 80 meters; traveling speed: 0–20 m/min). Designed around the core principles of high strength, long span, and superior maneuverability, the equipment is precisely tailored to meet the port's operational requirements:
Exceptional Lifting Performance
With a single-unit rated lifting capacity of 80 tons and a maximum working radius of 80 meters, the portal jib crane fully covers the port's current and foreseeable heavy-lift cargo handling needs.
Efficient Hoisting System
Equipped with a dual-winch synchronous drive design, the portal crane's hoisting speed ranges from 0.5 to 10 m/min and enables stepless speed regulation based on cargo weight.
High Mobility & Wide Coverage
Traveling along the port's dedicated rails, the mobile portal crane achieves seamless movement and continuous operation within the rail coverage area. The two units can operate independently or in coordination, providing full coverage of the entire wide working front without the need for repeated positioning or frequent vessel berth adjustments.
Advantages of Lightweight Truss Single Jib
- Adopting a high-strength steel structure truss jib, the jib crane reduces self-weight by 30% while increasing bending and torsion resistance by 25%, lowering the load on the portal base as well as the stress and construction costs of the rail foundation.
- The open truss structure minimizes wind resistance; an automatic anchoring device is activated when wind speed exceeds 20 m/s to ensure safe and stable operation.
- The unobstructed space beneath the jib delivers unparalleled visibility for the operator, facilitating precise judgment of cargo position and surrounding conditions.
Versatile Portal Base
Featuring a spacious box-type rigid frame structure with 4 sets of driving wheel assemblies and 2 sets of driven wheel assemblies, it ensures the portal crane's exceptional stability. The clearance under the base allows unimpeded passage of trains, trucks, and other port vehicles, achieving zero-interference land-side intermodal transportation and greatly optimizing the port's cargo flow.
On-site Installation: Multi-party Coordination to Tackle Key Challenges
As a core phase of the mobile portal crane's project, on-site installation
faces three major challenges: oversized equipment, high hoisting precision requirements, and complex operating environments. A "segmented hoisting + precise alignment + phased commissioning" plan was developed via multi-party coordination to ensure orderly progress.
- Pre-installation: Cleared obstacles in the hoisting radius, reinforced temporary platforms, and tested/adjusted rail foundation flatness.
- Transportation: Disassembled the Rail-mounted Mobile Portal Jib Crane into 8 core components (portal base, slewing platform, etc.), transported them to the site in batches via heavy flatbed trucks, avoiding integral transportation traffic issues.
- Hoisting: Adopted a dual-crane operation mode (400t crawler crane + 250t mobile crane).
- Post-installation: Completed interlock commissioning of hoisting, luffing, and traveling mechanisms; conducted 110% rated load static/dynamic tests; verified the monitoring system's real-time parameter display (load, wind speed, position, etc.).

Project Outcomes: Efficiency Gains, Deliver Value, Empowerment
The successful installation and commissioning of two YFMMPC8080
Mobile Portal Jib Cranes have significantly improved the port's operational efficiency and industry competitiveness.
- Operational Efficiency: Oversized cargo handling time has been cut from 48 hours to under 8 hours.
- Operational Range: With a maximum working radius of 80 meters, the cranes cover 3 deep-water berths, enabling flexible "one-crane multi-berth" operations.
- Operational Costs: External equipment reliance has been eliminated, saving approximately 8 million yuan annually in collaboration fees. Meanwhile, a 20% increase in cargo turnover driven by higher efficiency has indirectly boosted annual revenue by around 30 million yuan.
In addition, the project has established replicable experience for large-scale port crane installation, creating a standardized workflow covering equipment disassembly & transportation, on-site precision hoisting, multi-mechanism interlock commissioning, and intelligent system integration, which provides technical reference for future similar projects.
The full-set delivery of YFMMPC8080 Mobile Portal Jib Cranes is not only a key milestone for the port's equipment upgrading, but also a compelling demonstration of our company's technological prowess in heavy-duty port equipment manufacturing and installation.
