The Weihua Rail Mounted Gantry Crane (RMG) is designed for container handling in inland terminals, container yards, rail freight stations, coastal freight yards, and frontier wharfs. It integrates advanced technologies such as full digital AC frequency conversion, PLC control, and intelligent monitoring (CMS), ensuring high efficiency, precision, and safety in material handling operations.
Key Features of Weihua Rail Mounted Gantry Crane
U-type frame with double cantilever and rod: strong and lightweight.
Large gantry span and width for container loading and unloading.
360° rotating spreader providing excellent adaptability and efficiency.
Long traveling mechanism assembly for stable movement.
Comprehensive frame/gantry assembly and trolley assembly.
Full digital frequency conversion and PLC control technology.
High precision sensor data acquisition and industrial computer analysis system.
Electrical control system integrated with CMS for intelligent monitoring.
Structure and Components
The RMG crane mainly consists of steel structure, lifting mechanism, micro-transfer mechanism, spreader anti-sway system, crane travelling mechanism, container spreaders, electrical equipment, and other auxiliary equipment. It adopts frequency conversion, PLC control system, and CMMS fault detection system, complying with standards including GB/T19683-2005, JT/T566-2004, ISO, FEM, and JIS.
Applications
Container stacking and transport in inland terminals and container yards.
Rail freight stations and coastal freight yards handling standard containers.
Flexible lifting of 20ft, 40ft, and 45ft containers using dedicated spreaders.
Efficient operations in petrochemical, logistics, and industrial material handling.
Types & Mechanisms
Double Cantilever Gantry Crane: Large space between outriggers for containers to pass through, forming a U-shape combined with girder forming N-shape.
Non-Cantilever Crane: Simple structure where containers do not pass between outriggers.
Stabilization: Rope-type mechanisms can use dampers; rigid type uses inherent rigidity. Optional anti-sway device improves operational stress and efficiency.
Drive & Safety: Three-in-one gear motors for long travel and cross travel, 270° trolley rotation, anti-breaking shaft, wind warning, anti-tipping, and other safety systems.
