The Rubber-Tired Gantry Crane (RTG) is the core equipment for achieving efficient and flexible container handling in modern container yards. Leveraging years of deep technical expertise in the material handling field, Weihua Group has created its high-performance RTG product series by deeply integrating high mobility, green energy efficiency, and intelligent control. These cranes are widely used in global ports, railway hubs, and logistics bases.
Weihua Rubber-Tired Gantry Crane (RTG) is a specialized piece of equipment used for loading, unloading, stacking, and transferring containers within a container yard. Unlike rail-dependent counterparts, it is supported by pneumatic rubber tires, requires no fixed tracks, and can move and turn freely within the yard, offering great operational flexibility and maximizing yard space utilization.
The design and manufacturing of the RTG strictly adhere to stringent international and national standards such as DIN, FEM, IEC, and GB, ensuring its global applicability and high reliability. The power system offers a variety of environmentally friendly options, including diesel generator sets, shore power cable reels, and lithium battery hybrid power, to meet the green operation needs of different terminals.
Features & Advantages
Superior Operational Performance & Stability
1. Precise and Efficient Anti-Sway: Employs a combined mechanical and electrical双向柔性 anti-sway system that quickly dampens the swing of the spreader and container, significantly reducing alignment time and improving operational efficiency and safety.
2. Intelligent Trajectory Control: Optional intelligent optimization of operation paths and automatic/semi-automatic control technologies simplify operation and achieve optimal handling routes.
3. Intelligent Crane Travel Correction: Equipped with automatic deviation correction and fine-tuning technology for the gantry, ensuring straight-line travel accuracy over long distances without rails, preventing drift.
Comprehensive Safety Assurance
1. Multiple Safety Protections: Integrates comprehensive safety devices such as high-wind alarms, dynamic safety scanning, anti-tipping, overload, and偏载 protection,构建 a全方位 protection system.
2. High Redundancy in Core Components: Key mechanisms like hoist motors and brakes are designed with ample safety margins and ultra-long life, ensuring reliability under heavy-load, high-frequency conditions.
Leading Green Energy-Saving Technology
1. Diverse Power Options & Energy Recovery: Offers multiple solutions like diesel-electric, pure electric, and lithium battery hybrid. In shore power or lithium battery modes, it utilizes energy feedback technology to recover energy during lowering/braking back to the grid, achieving significant energy savings.
2. Efficient Drive System: Main mechanisms use fully digital AC variable frequency drives and PLC control for smooth operation and lower energy consumption.
Intelligent Management & Remote Service
1. Intelligent Service System: Equipped with the CMS (Condition Monitoring System) for real-time remote monitoring of equipment status, fault log查询, and operational data analysis, enabling predictive maintenance.
2. Supports Remote Upgrades: The electrical control system预留 remote control interfaces, providing a foundation for future upgrades towards fully automated, unmanned remote operation of the terminal.
Structural Composition
The RTG is a complex integrated system. Its core modules work together to perform precise container handling tasks. The main components include:
Component
Function Description
Gantry Structure
The main steel structure composed of front and rear large gantry frames and the top girder. It is the skeleton of the equipment, determining the span and lifting height.
Crane Travel Mechanism
The tire assembly at the base of the gantry, driving the entire crane to move longitudinally within the yard. It can perform straight travel, transverse movement, 90-degree steering, and原地 rotation.
Hoist Trolley
Travels transversely along the rails on the main girder, responsible for precise positioning above designated container slots.
Hoisting Mechanism
Mounted on the hoist trolley, this is the core power unit. It lifts and lowers the spreader via wire ropes to handle containers.
Container Spreader
The spreader can automatically telescope to fit containers of different sizes (e.g., 20ft, 40ft) and uses twist lock mechanisms for automatic locking and releasing.
Power System & Operator’s Cab
The power room typically houses a diesel generator or power conversion unit. The cab provides operators with a panoramic view and an integrated intelligent control interface.
Applicable Industries & Fields
Weihua RTGs primarily serve modern logistics nodes with high demands for container handling efficiency. Specific application areas include:
Large Container Ports & Terminals: Used for loading, unloading, stacking, and transferring containers in the storage yard behind the wharf; key equipment for enhancing port throughput capacity.
Railway Container Centers: Efficiently handles container transfers between trains and trucks within railway freight stations.
Inland Ports & Large Logistics Parks: Manages container storage and allocation within bonded areas and logistics hubs.
Major International Projects: Weihua lifting equipment has been widely used in numerous key domestic and international projects, and its RTG products are also suitable for supporting large-scale logistics infrastructure construction.
