Advantages & Features

Structural Composition

The Weihua New Chinese Style A-type double-girder gantry crane is mainly composed of the following modular components, featuring a compact structure that facilitates transport, installation, and maintenance:

Gantry Structure: Consists of two box-type main girders, A-type flexible and rigid legs, and a bottom crossbeam. The整体 adopts a low headroom, offset rail design. The structure is optimized using finite element analysis, achieving maximum lightweighting while ensuring strength and stiffness.
Crane Travel Mechanism: Drives the entire crane longitudinally along the ground rails. Uses three-in-one geared motors for separate drives, resulting in a compact structure. Some large-tonnage models adopt an advanced structure combining multi-stage equalizing beams and bogies, connected via half couplings, ensuring uniform load distribution on wheels, smooth operation, and good adaptability to rails.
Hoist Trolley: Runs on the main girder rails, responsible for lifting and transversely moving the load. Its drive mechanism is typically integrated for smooth operation.
Hoisting Mechanism: The core power unit of the crane. Uses high-quality components such as hardened gear reducers, dedicated inverter motors, steel drums, and compacted strand wire ropes. Supports synchronous control for dual lifting points (on large-tonnage models), enabling simultaneous lifting and lowering for safer and more stable operation.
Control System: The entire crane uses variable frequency speed regulation + PLC (Programmable Logic Controller) control. This forms the foundation for intelligence, supporting smooth starting/braking, speed adjustment, and various safety interlocks. Optional AICrane intelligent system enables automatic positioning and anti-sway.
Operating System: The ergonomically designed operator’s cab offers a wide field of vision. Multiple operation modes are available, including cab operation, ground pendant control, and wireless remote control, adapting to different working condition requirements.

The New Chinese Style Electric Single Girder Crane is a world-class single-girder bridge crane. It features European optimized design, characterized by lightweight construction, low wheel load, low headroom, and a high-rigidity structure, making it suitable for material handling in workshops, warehouses, and similar locations.
The New Chinese Style Electric Single Girder Crane is a light lifting device designed and manufactured according to GB/T 3811-2008 and JB/T 1306-2008 standards, used in conjunction with CD and MD electric hoists. Its rated capacity is 3t-10t, span is 7.5m~22.5m, working class is A3 or A4, and lifting height is 6-12m. The main operation modes are ground control (pendant control, remote control, or pendant + remote control). Non-standard customized designs are also available based on actual working condition requirements.

Structural Composition

The New Chinese Style Electric Single Girder Crane mainly consists of end carriages, a main girder, a capacity plate, a corner trolley, and a power supply device. The features of each component are as follows:

End Carriages: The end carriages connect the main girder at both ends, providing lateral stability and the load-bearing foundation for the crane. They are the core structure connecting the main girder to the rails, enabling the crane to travel along the rails.
Main Girder: Responsible for bearing the weight of the hoisting mechanism, trolley, and other components, while also supporting the weight of the load during lifting, ensuring the stability and safety of lifting operations.
Capacity Plate: An identification component located on the main girder or end carriage, used to display the rated capacity.
Corner Trolley: A mobile trolley structure on the main girder that carries the hoisting mechanism.
Power Supply Device: The system that provides electrical power to the crane, including components such as cables, conductor rails, and current collectors. It meets the power demands for main girder travel, trolley movement, and hoisting mechanism operations, serving as the “power guarantee” for normal equipment operation.

Advantages & Features
