Frequently Asked Questions (JZD50t-32m Drawing Technical Analysis)
Addressing core inquiries regarding the 32m wide span design, ISO M7 duty rating, rotation unit functionality, and wheel load limits.
1. What are the advantages of the 32m wide span combined with 7.5m cantilevers?
The 32m span creates an extensive storage block capacity accommodating multiple container rows, while the dual 7.5m cantilevers (total bridge length 47.14m) extend the working envelope over external truck lanes and rail spurs, maximizing terminal throughput.
2. What is the specific function of the Rotation Unit in this JZD50t model?
The rotation unit allows the spreader and suspended container to rotate horizontally, enabling operators to correct container orientation swiftly when aligning with twist-locks on trucks, rail cars, or dense stack layouts.
3. Why is keeping the maximum wheel load pressure under 35 tons important?
Despite a robust total machine weight of 225 tons, optimizing the load distribution across multiple bogies keeps individual wheel pressure below 35 tons, preventing excessive rail wear and substantially lowering civil foundation reinforcement costs for the terminal.
4. How does the ISO M7 duty class benefit continuous port operations?
ISO M7 represents an ultra-heavy-duty classification designed for high-frequency, severe service conditions. It ensures that all structural components, gearboxes, and the 150kW hoisting motor operate well within safe thermal and mechanical fatigue limits during 24-hour intensive terminal cycles.
