Rubber-Tyred Gantry Crane

A Rubber-Tyred Gantry Crane (abbreviated as RTG) is a specialized lifting machine used for stacking operations in container yards. Rubber tyres enable the crane to travel within the yard, and a trolley travels along the track on the crossbeam of the gantry frame to load and unload containers from container trucks and perform stacking operations. The RTG adopts mechanical hydraulic devices and directional guidance devices such as radio induction to maintain straight-line travel within the yard. It can also perform 90° right-angle steering to achieve turning and yard transfer operations. RTGs produced by Wuxin can adopt multiple power supply methods including diesel generator sets, mains electricity, and lithium batteries. They comply with the latest domestic and international standards such as GB, FEM, DIN, IEC, and AWS, featuring safety and stability, good maneuverability, customizability, low operation and maintenance costs, and energy efficiency and environmental friendliness.

Product Advantages

1. Wire Rope Winding System

4-rope: Enables spreader slewing and tilting functions

8-rope: Good anti-sway effect; spreader has slewing and traversing functions

16-rope: Good sway reduction effect; spreader has slewing and traversing functions

2. Spreader Interchangeability

Multi-mode spreader (20'/40'/45' twin-lift) for rapid switching, suitable for special container operations

3. Trackless Omnidirectional Movement

Independent steering system with a minimum turning radius ≤15m, enabling 360° free movement within the yard

4. Economy

Supercapacitor energy storage system achieves potential energy recovery, increasing energy savings rate to 30%; the energy feedback system reduces carbon footprint by more than 15%

5. Modular Structural Design

Facilitates maintenance and reduces repair and parts replacement costs.

6. Tyre Life Extension Technology

Automatic deviation correction and tyre pressure monitoring extend tyre replacement intervals

7. Wind Resistance

Wind resistance up to 20m/s (equivalent to Beaufort scale 8), equipped with automatic rail clamps and anti-overturning system

8. Active Safety System

3D anti-collision system (container truck/container/personnel) with response time ≤150ms

Dynamic load monitoring system with automatic overload lockout

Emergency braking distance ≤3m (under rated load at 20km/h travel condition)

9. Container Truck Anti-Lifting

By detecting the positional relationship between the container truck and the container, it determines whether the container is hooked onto the chassis, preventing safety accidents caused by lifting the container truck.

10. Anti-Crush Cab System

During the spreader loading process, it detects whether the container truck has moved, preventing cab-crushing accidents.

11. Operation Area Electronic Fence

Identifies personnel and other abnormal objects within the area and implements mechanism restriction strategies to enhance equipment operation safety.

12. Anti-Bowling System

Real-time identification of container conditions in the yard area, combined with the automatic control system, prevents collision with yard containers during operations, improving operation safety.

13. Automatic Deviation Correction

Real-time detection of position deviation of the gantry crane's gantry legs on both sides, automatically adjusting motor speed to achieve automatic deviation correction, avoiding rail gnawing and extending crane service life.

14. High Power Factor, Low Harmonics (Features)

Adopts intelligent compensation and harmonic elimination system to improve power factor, reduce line losses, and optimize power quality.

15. One-Key Anchoring

Adopts precise positioning technology and electric anchoring device to achieve one-key automatic anchoring.

Application Scenarios

Rubber-tyred container gantry cranes (abbreviated as yard cranes, RTG) are mainly used in ports, wharves, container yards, etc., for lifting and transporting containers and general cargo. They run on rubber tyres on flat ground. They can adopt multiple power supply methods including diesel generator sets, mains electricity, and lithium batteries.

Optional Configurations

1. Wire Rope Sway Reduction System (Optional): Fully automated cranes can be designed with 8-rope sway reduction or electronic sway reduction; non-automated cranes can be designed with auxiliary rope sway reduction or X-type sway reduction. Good sway reduction effect.

2. Slewing Trolley (Optional): Enables load slewing (-10°~+190°).

3. Energy Recovery System (Optional): Recovers energy from load lowering, reducing energy waste.

4. Intelligent Lubrication (Optional): Enables timed and quantitative automatic lubrication at different lubrication points.

5. Intelligent Online Monitoring System (Optional): Real-time online monitoring of the operating status of key crane components (including vibration, temperature rise, etc.) and can transmit data to a remote control center.
