Container gantry cranes are core lifting equipment for port terminals, railway intermodal yards and inland logistics storage yards, specially designed to complete stacking, loading/unloading and transshipment operations of 20-foot, 40-foot and 45-foot standard containers.
At present, numerous logistics ports and inland container terminals are commonly plagued by pain points including low transshipment efficiency, poor site utilization, container collision and abrasion losses, high labor costs and inflexible equipment scheduling. Having engaged in port machinery manufacturing for more than 20 years, Henan Mine independently developed two main models: RTG rubber-tyred container gantry cranes and RMG rail-mounted container gantry cranes, which provide one-stop solutions to all lifting challenges throughout the entire workflow of container yards.
Rubber-tyred container gantry crane (flexible mobile type)
Mobility Advantages: Equipped with heavy-duty solid engineering tires, it supports 360° in-place rotation and crab lateral movement. No steel rails need to be laid, and it can transfer to provide support across yards within 15 minutes.
Dual Power Configuration: A mains cable reel delivers energy-saving and low-noise operation for daily work, while an on-board diesel generator set handles yard transfers and power outages to enable non-stop all-weather operation.
Stacking Capacity: It can stack containers up to 6 layers high. An optional twin spreader allows simultaneous lifting of two 20-foot standard containers, doubling the single-cycle handling volume.
Applicable Scenarios: Small and medium-sized inland container yards, temporary transit cargo yards, port zones with frequently adjusted layouts, and cross-border logistics transfer stations.
RMG Rail-Mounted Container Gantry Crane (High-Efficiency Fixed Type)
Stability Advantages: Travels along pre-embedded steel rails with centimeter-level positioning accuracy. It is suitable for the renovation of automated unmanned yards and runs smoothly without deviation.
Energy-saving Advantages: Equipped with full-electric drive and energy feedback system, its energy consumption during continuous heavy-load operation is 30% lower than that of RTG, cutting long-term operating costs significantly.
Intelligent Compatibility: Can connect to yard WMS warehousing systems to realize fully automatic unmanned stacking and remote centralized control, greatly reducing on-site operators.
Applicable Scenarios: Large deep-water port container terminals, dedicated railway container yards, and high-throughput fixed standardized container storage areas.
Five Core Competitive Advantages of Henan Mine Container Gantry Cranes
1.Heavy-Duty Anti-Corrosion Steel Structure for Long Service Life and Superior Corrosion Resistance in Coastal Ports
The whole machine is fabricated with thickened box-type double main beams via welding, and a complete heavy anti-corrosion coating process using epoxy zinc-rich paint is adopted to resist erosion from coastal salt fog, rainwater and dust. With standardized maintenance, the machine can operate stably for 15 to 20 years.
2.Intelligent Variable Frequency Anti-Sway System to Eliminate Cargo Damage Caused by Container Collisions
Equipped with PLC variable-frequency synchronous anti-sway electric control system, it eliminates container swing within 3 seconds with stacking positioning error no more than ±5mm. Matched with telescopic and rotary special container spreaders compatible with all sizes of standard containers, it fundamentally prevents container scratches and deformation.
3.Comprehensive Multiple Safety Protections for Smooth Domestic and Foreign Trade Acceptance
Standard configurations include laser area anti-collision system, automatic power cut-off under overload, lifting/travel limit switches, gantry traveling deviation correction, emergency stop self-locking and tire anti-slip locking devices. The machine holds complete export qualifications including TSG special equipment manufacturing license, ISO certification and CE certification, enabling smooth acceptance for domestic safety supervision inspections and overseas port projects.
4.Low Operation and Maintenance Cost with Short Investment Payback Period
One container gantry crane can replace 3 to 5 reach stackers, greatly cutting labor costs for operators and fuel expenses. Modular universal spare parts and centralized lubrication points simplify daily maintenance. Most yards can recover the equipment procurement cost within 1 to 3 years.
5.Custom Non-Standard Design with Full Parameters to Adapt to Various Working Conditions Worldwide
Customizable parameters as required include lifting capacity (30t/40t/45t), yard span, lifting height and power supply voltage. Three operation modes are available: cab operation, wireless explosion-proof remote control and remote central control. Explosion-proof container gantry cranes can be customized for chemical and hazardous goods storage yards.
If your coastal port, railway freight yard or inland logistics yard has demands for efficient container loading, unloading and stacking, professional port machinery engineers from Henan Mine can conduct free on-site yard surveys, calculate foundation load-bearing capacity and provide exclusive customized solutions for rubber-tyred gantry cranes (RTG) and rail-mounted gantry cranes (RMG). Simply provide yard span, required lifting tonnage, container stacking layers and operating environment, and we can offer accurate direct manufacturer quotations on the same day, delivering one-stop services covering production, delivery and on-site installation & commissioning.

FAQs
Q1: Should the yard adopt RTG rubber-tyred or RMG rail-mounted container gantry cranes?
A: RTG rubber-tyred gantry cranes are suitable for small and medium-sized inland yards that require flexible cross-area relocation and have limited budgets. RMG rail-mounted container gantry cranes are the top choice for large fixed terminals with high throughput and yards planned to be renovated into fully automatic unmanned yards.
Q2: Can a container spreader lift two 20-foot containers at once?
A: A telescopic twin-lift spreader can be optionally equipped to grab two 20-foot containers simultaneously, doubling the handling efficiency per cycle.
Q3: Can the existing yard be upgraded for fully automatic unmanned operation?
A: Both RTG and RMG models support intelligent upgrading. They can connect to the yard warehouse management system to realize automatic container identification, automatic bay allocation, and unmanned stacking and transportation, without full replacement of all equipment.
