New Chinese style single-girder crane

The Weihua New Chinese style electric single-girder overhead crane is an ultra-low headroom, light and small lifting device. The electric hoist is positioned on one side of the main girder, which effectively increases the hook's service space. This design feature helps reduce the required height and construction cost of the workshop, making it particularly suitable for locations where the workshop headroom is limited.
Specifications
  • Lifting capacity: 3-10t
  • Span: 7.5-22.5m
  • Lifting height: 6-12m
  • Working class: A3-A4
Introduction

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

Enhanced Space Utilization
The ultra-low headroom design and the layout with the electric hoist positioned beside the main girder effectively increase the hook service space and reduce the required building clearance, thereby lowering plant height and construction costs.
Smooth & Safe Operation
A design with a large trolley wheelbase enhances operational stability. The trolley travel mechanism uses a conical rotor motor brake and open gear transmission.
Compact Structure & Good Performance
Characterized by a compact structure, good rigidity, sensitive operation, low noise, and high safety and reliability.
Non-Standard Customization Supported
For spans and lifting heights exceeding standard specifications, non-standard customized designs are available based on actual working condition requirements.
