Reliable Rail Mounted Gantry Crane with Long Service Life

♦Steel Structure: The steel structure forms the backbone of the rail mounted gantry crane. It consists of a box-type main girder designed to provide high rigidity and stability across long spans. The crane legs are configured with one rigid leg and one flexible leg to minimize stress on the rails, while the trolley frame supports the hoisting mechanism and ensures smooth movement along the span.

♦Hoisting and Traveling Mechanisms: The RMG crane is equipped with advanced hoisting and traveling systems. The hoisting unit, usually a wire rope hoist or winch, provides the power for lifting heavy containers safely and efficiently. The trolley system moves laterally across the span, while the gantry traveling system operates along fixed rails, driven by multiple motors and frequency converters for stable and precise motion.

♦Electrical and Control System: The electrical system powers the crane through cable drums or conductor rails, ensuring reliable energy delivery. Control options include operator cabins, radio remote controls, and even fully automated modes. With PLC integration, the crane supports intelligent scheduling, fault detection, and real-time monitoring, making it highly efficient in modern logistics environments.

♦Safety Systems: Comprehensive safety systems are integrated into the rail mounted gantry crane to guarantee secure operations. These include overload protection, anti-sway technology, and limit switches for travel and lifting. Emergency stop functions, wind speed detectors, and storm locks further enhance safety, particularly in coastal or outdoor terminals.

♦Lifting Capacity: Choose an RMG crane with lifting capacity that matches your container weights and overall throughput. Undersized equipment may slow operations, while oversized capacity increases unnecessary costs.

♦Span and Height: The span and lifting height should be determined by your yard layout and stacking density. Wider spans and greater lifting heights allow for higher container stacks and improved land use efficiency.

♦Duty Class: Select the appropriate duty class, such as A6 or A7, to ensure the crane can handle heavy-duty and continuous operations without excessive wear. This is critical for high-intensity terminals.

♦Power Supply Options: Consider whether a cable drum or busbar system suits your operation. Cable drums are flexible, while busbars offer stable, continuous power for large-scale facilities.

♦Automation Level: Decide on manual, semi-automated, or fully automated control based on labor costs, efficiency goals, and technological readiness. Automation enhances precision and reduces downtime.

♦Environmental Conditions: Evaluate wind load, seismic resistance, and anti-corrosion requirements. Outdoor cranes must withstand harsh weather and remain reliable in coastal or seismic regions.

♦Budget and Lifecycle Costs: Factor in both capital expenditure (CAPEX) and operational expenditure (OPEX). A well-designed RMG crane minimizes maintenance and energy consumption, lowering total lifecycle costs.
