Product Description
The single girder semi-gantry crane is a versatile lifting solution capable of handling diverse industrial loads including heavy machinery (engines, presses), construction materials (steel beams, concrete panels), shipping containers, palletized goods, industrial components (molds, steel rolls), and warehouse cargo with capacities typically up to 20 tons. Its unique hybrid design - combining one elevated runway-supported side with one ground-supported side - enables flexible material movement in facilities with partial overhead restrictions, providing precise load positioning for loading/unloading, assembly, and transport operations while maintaining stability across various industrial environments. The actual load capacity depends on specific configurations including span length, girder strength, and structural support requirements.

Our Advantages
1:Cost-Effective Solution
Lower initial investment compared to double girder or full gantry cranes
Reduced installation and foundation costs
2:Space-Saving Design
Requires only one elevated runway (unlike full gantry cranes)
Ideal for facilities with partial overhead obstructions
3:Versatile Applications
Suitable for both indoor and outdoor operations
Handles diverse loads (1-20+ tons) across multiple industries
4:Easy Installation & Mobility
Minimal foundation requirements on ground-supported side
Can be relocated if needed (unlike fixed bridge cranes)
5:Improved Headroom
Single girder design provides greater hook height than double girder alternatives
Maximizes vertical workspace utilization
6:Adaptable Configuration
Adjustable legs accommodate uneven floor conditions
Customizable span lengths and lifting heights
7:Energy Efficient Operation
Requires less power than larger crane systems
Modern models feature regenerative braking systems
8:Low Maintenance Requirements
Simplified mechanical design with fewer components
Easy access for inspection and servicing
9:Precision Control
Smooth load positioning with variable frequency drives (VFD options)
Available with pendant or wireless remote controls
10:Structural Flexibility
Can integrate with existing building columns/supports
Open design allows unobstructed floor space beneath
11:Safety Features
Standard overload protection systems
Anti-collision devices available for multiple crane installations
Packaging & Shipping
To ensure safe and damage-free transportation, cranes must be securely packaged in heavy-duty wooden crates or steel frames, with critical components like hoists and girders disassembled if oversized and properly strapped. Electrical systems and sensitive parts should be wrapped in waterproof, anti-corrosion materials, while all packages must be clearly labeled with weight, center of gravity, and lifting points. During transit, components must be firmly fastened using chains or straps to prevent shifting, with special attention given to corrosion protection for sea freight and route planning for oversized shipments. These measures guarantee that cranes arrive in optimal condition for assembly and operation.
