Components of Rail Mounted Container Gantry Crane
Rail mounted container gantry crane (RMG) generally includes the following units, steel frame, hoisting mechanism, minimum slewing mechanism, spreader anti-shaking mechanism, crane travel mechanism, trolley traverse mechanism, container spreader, electrical equipment and other accessory equipment for safety, Inverter, PLC and CMMS, etc.
Box Girder Construction: High-strength steel beams for rigidity and load distribution.
Rail System: Precisely aligned tracks with anti-derailment guards and wear-resistant rails.
Trolley & Hoist: Dual-motor hoists with anti-sway technology; regenerative braking for energy recovery.
