Overview
A ME Shipbuilding Gantry Crane is a high-performance lifting equipment specifically designed for modern shipbuilding industries. It is widely used for hull block hoisting, large equipment installation, and component transportation within dry docks/slipways. With its exceptional load-bearing capacity, precise control, and stability in complex working conditions, this crane has become a core asset for enhancing shipbuilding efficiency and ensuring operational safety. The ME series integrates advanced mechanical design, intelligent control systems, and high-strength materials, delivering efficient, reliable, and energy-saving lifting solutions.
Key Design Features
High Load Capacity & Robust Stability
1.Double-Girder Structure: Optimized double-girder box design, combined with high-strength low-alloy steel, ensures superior torsional and bending resistance under large spans (up to 150 meters), with a maximum lifting capacity exceeding 500 tons to meet the demands of ultra-large hull block assembly.
2. Rigid Portal Frame: Four-leg support structure with dynamic balance technology adapts to uneven dock/slipway surfaces. Wind-resistant design (up to Level 10 wind) guarantees stability during operation.
3. Rail Adaptive System: Equipped with rail alignment correction and anti-derailment mechanisms to minimize track wear and extend service life.
Precision Control & Intelligence
Variable Frequency Drive (VFD): Full-range frequency control enables smooth speed regulation for hoisting, trolley, and gantry travel, achieving positioning accuracy of ±5 mm for precision assembly.
1. Anti-Sway Technology: Real-time load swing monitoring via sensors automatically adjusts motion speed, reducing stabilization time and boosting efficiency.
2. Remote Monitoring & Diagnostics: IoT-enabled modules allow real-time equipment status tracking, fault alerts, and data analysis via PC/mobile devices, enabling predictive maintenance.
Modular & Customizable Design
1. Modular Components: Standardized modules for main girders, legs, and other core parts facilitate rapid assembly, disassembly, and transportation.
2. Custom Configurations: Tailored to shipyard layouts (e.g., span, lifting height) and processes, with options for hooks, electromagnetic grabs, or specialized lifting tools to suit diverse shipbuilding requirements.
