40T-45m Gantry Crane
This product is a large-span, highly flexible rubber-tired gantry crane (RTG), designed for efficient container yard operations in modern ports, with core advantages of a 40-ton rated capacity and an extra-wide 45-meter span. By integrating fully variable frequency drives, intelligent positioning, and green energy technologies, it achieves a daily average single-unit workload of ≥300 TEUs across full container stacking, transfer, and loading/unloading processes, while reducing overall energy consumption by 35% compared to traditional gantry cranes, making it a benchmark equipment for intelligent port upgrades.
Core Parameters and Design Focus
The 40T-45m rubber-tired gantry crane (RTG) is engineered around its 40-ton rated capacity and 45-meter ultra-wide span. This combination makes it an ideal solution for modern container yards facing high-density storage and high-efficiency turnover demands. The large-span design significantly expands the coverage area per unit, reducing equipment movement frequency—especially suitable for busy ports with limited yard space but high container volumes.
Technical Highlights
This product integrates multiple advanced technologies to deliver exceptional performance and environmental efficiency:
Fully Variable Frequency Drive System
- As the core power system, fully variable frequency drive technology ensures stepless, smooth speed control for hoisting, trolley travel, and gantry movement.
- Dramatically reduces starting shocks and mechanical wear, extending equipment lifespan and improving operator comfort.
- Serves as the foundational technology for achieving high efficiency and energy savings.
Intelligent Positioning and Control System
- Equipped with high-precision sensors and advanced algorithms for automatic spreader alignment and precise container placement.
- Supports semi-automated and even fully automated operation modes, greatly reducing operator workload while enhancing accuracy and efficiency.
- Features comprehensive status monitoring and fault diagnostics to ensure safe and reliable operation.
Green Energy Integration
- Aligned with environmental trends, it can adopt a grid power + energy storage (lithium battery) hybrid solution, or be optionally equipped with a photovoltaic power generation system for auxiliary power supply.
- Energy recovery technology effectively captures regenerative energy during braking and reuses it.
- These technologies collectively enable a 35% reduction in overall energy consumption compared to conventional gantry cranes.
Outstanding Performance
Leveraging the integration of core parameters and advanced technologies, the 40T-45m RTG demonstrates remarkable operational capabilities:
- Exceptional efficiency: In typical container stacking, transfer, and loading/unloading workflows, the single unit averages over 300 TEUs per day, effectively alleviating port throughput pressure.
- Significant energy savings: Consumes up to 35% less energy than conventional RTGs, delivering substantial long-term cost savings for port operations.
- Flexible and stable operation: The rubber-tired design provides excellent site adaptability and flexible repositioning within the yard, while advanced control systems ensure smooth and precise operations.
