The single girder semi gantry crane is a lightweight and versatile lifting solution designed for workshops, warehouses, and outdoor material handling applications. It combines the advantages of overhead cranes and gantry cranes, with one side of the crane running on an elevated runway beam while the other side is supported by ground-based legs.
This special structure reduces the need for full gantry supports, saving installation space and lowering construction costs. The leg height can be customized according to actual site conditions, making it suitable for buildings with different layouts and height requirements.
The crane features a simple structure, lightweight design, easy installation, and good wind resistance. The main girder usually adopts a box-type structure with high strength and rigidity, ensuring stable operation during lifting tasks.
The hoisting mechanism adopts a reliable wire rope electric hoist with stable performance, durability, and convenient maintenance. The crane traveling system uses variable frequency drive or three-in-one drive technology to achieve smooth movement, precise positioning, and efficient operation.
Due to its flexible installation method, the single girder semi gantry crane is an ideal choice for factories, warehouses, material yards, and other workplaces where full-span overhead crane installation is not practical.
Factories and Warehouses:
Used for material transfer, equipment handling, and production line support in assembly workshops, storage areas, and maintenance facilities, especially where space is limited or existing structures cannot support a full overhead crane.
Material Yards:
Suitable for handling steel materials, components, and other goods, improving loading, unloading, and storage efficiency.
Construction Sites:
Used for lifting construction materials such as steel structures, precast concrete components, and machinery parts, helping improve construction efficiency.
Special Working Environments:
Can be customized for specific applications, including clean workshops and environments requiring special protection treatment.
Compact Structure
Single girder design reduces overall weight and installation requirements, making it suitable for space-limited workplaces.
Flexible Installation
One side supported by building structures and the other side supported by legs, allowing flexible adaptation to different factory layouts.
Smooth Operation
Frequency conversion speed control ensures stable starting, accurate positioning, and reduced impact during operation.
Safe and Reliable Performance
Equipped with overload protection, travel limit switches, and other safety devices to ensure reliable lifting operations.
Energy Efficient Design
Integrated drive system reduces energy consumption and improves operating efficiency.
Low Noise Operation
Optimized transmission system provides quieter running performance and a more comfortable working environment.
