Description
Weihua Rubber-Tyred Gantry Crane (RTG), also known as a rubber-tired container gantry crane, is a specialized container stacking and handling equipment launched by Weihua Group for port terminals, container yards, and railway transfer stations. This product is supported on inflatable rubber tires and is primarily driven by a diesel generator set. It can also be configured with cable reels, mains power, or lithium batteries according to customer needs. It is a highly mobile and adaptable container lifting machine.
As a core operating equipment in container yards, RTGs are widely used in port terminals, container yards, railway container transfer stations, and highway container transfer stations, undertaking key tasks such as container stacking, handling, and loading/unloading. Designed, manufactured, and inspected according to advanced domestic and international standards such as DIN, FEM, IEC, AWS, and GB, the product boasts stable performance, long service life, high production efficiency, and low sensitivity to ground unevenness.
Structurally, the rubber-tired gantry crane mainly consists of a trolley traveling mechanism, a trip trolley traveling mechanism, a gantry frame, a power supply system, and specialized container spreaders. The gantry consists of a U-shaped frame and a base beam, supported by inflatable rubber tires, and travels along designated aisles. The machine features multiple travel modes, including straight travel, lateral travel, 0-90° turning, and stationary turning, allowing for flexible and convenient site changes.
Depending on the lifting capacity, standard RTGs range from 35 to 65 tons, with a span covering six rows of containers plus a truck aisle (approximately 23.5 meters), and a stacking height of up to 6 or more layers (6 layers stacked, 7 layers passable). The product can lift 20-foot, 40-foot, and 45-foot standard containers and hydraulic storage tanks, employing specialized container spreaders and equipped with a comprehensive anti-sway system, safety indicators, and overload protection devices to ensure the safety of operators and equipment.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Superior Site Mobility – Trackless, Flexible Relocation
The core competitiveness of tire-mounted gantry cranes lies in their rubber tire travel system, a design that overcomes the site limitations of traditional rail-mounted gantry cranes:
No Rails Required, High Site Adaptability: Utilizing pneumatic rubber tires for support, no rail foundation is needed, allowing for flexible adjustment of the work area according to the yard layout. It exhibits excellent adaptability to uneven ground and is less sensitive to uneven surfaces.
Omnidirectional Mobility:The trolley traveling mechanism can achieve multiple movement modes, including straight travel, lateral travel, 0-90° turning, and in-situ turning. The direction of travel can be adjusted at any time during site changes without the need for dedicated steering facilities or occupying additional yard space.
Incline Travel and Correction Functions:Equipped with 20° or 45° incline travel capabilities, combined with unique trolley correction and fine-tuning technology, it ensures the entire machine travels in a straight line under complex working conditions, preventing deviation.
Right-Angle Turning Design: The U-shaped frame structure, combined with a specialized turning mechanism, enables 90° right-angle turns, maximizing space utilization for aisle transfers within limited yard space.
Professional Container Spreader – Efficient Loading and Unloading, Precise Container Alignment
Weihua RTG is equipped with specialized container spreaders, offering the following technological advantages:
Multi-Size Compatibility: Capable of lifting 20-foot, 40-foot, and 45-foot standard containers and hydraulic storage tanks, adapting to the diverse needs of different shipping companies and cargo owners.
360° Rotary Lock Control: Equipped with a rotary lock mechanism, the spreader can be quickly locked and unlocked with container corner fittings via the cab, ensuring simple, safe, and reliable operation.
Flexible Intelligent Container Alignment Technology: Optional flexible intelligent container alignment and locking pin technology assists operators in quickly aligning the spreader with the container, significantly improving operational efficiency.
Telescopic Spreader Design: The spreader length automatically adjusts according to container specifications, allowing for loading and unloading of containers of different sizes from 20-foot to 40-foot without changing the spreader.
Multiple Power Solutions – Energy-Saving, Environmentally Friendly, and Flexible Configuration
Weihua RTG offers a variety of power combination solutions to meet the operational needs of different port customers:
Power Type | Characteristics | Applicable Scenarios
Diesel generator set | Independent power supply, high mobility | Terminals and temporary storage yards without mains power access
Mains power (cable reel) | Low operating costs, zero emissions | Fixed operating areas with power supply access
Hybrid power (diesel + lithium battery) | 30%-50% reduction in fuel consumption, energy-saving and environmentally friendly | Modern terminals pursuing green operations
All-electric (lithium battery) | Zero emissions, low noise | Operating areas with strict environmental requirements
Energy Feedback Technology: When the power source is mains power or lithium battery, energy feedback technology is used to feed the regenerative energy generated by the mechanism's braking back to the power grid or battery system, achieving energy recovery and utilization.
High-Efficiency Anti-Sway System – Smooth Operation and Precise Positioning
Spreader sway is a key factor affecting container loading and unloading efficiency. Weihua RTG offers a variety of anti-sway technology soluti
