Mobile Double Girder Semi-Gantry Crane
Product Overview
The Weiyuan Mobile Double Girder Semi-Gantry Crane is a versatile and powerful lifting solution that blends the stability of a gantry crane with the flexibility of a bridge crane. Its unique semi-gantry structure, with one end running on a building-mounted rail and the other on ground-level tracks, makes it ideal for facilities where a full gantry system is impractical. This design efficiently utilizes existing factory structures to provide safe and effective lifting in limited spaces. Comprising a lifting trolley, robust double main girders, supporting legs, and advanced electrical controls, this crane is perfectly suited for workshops, warehouses, logistics centers, and docks.
Product Advantages
Space-Efficient Design
By using one elevated runway attached to the building structure, the semi-gantry design frees up valuable floor space, making it a smart alternative to full gantry cranes while reducing infrastructure costs.
Enhanced Stability and Capacity
The double-girder construction provides superior stability and allows for higher lifting capacities and wider spans compared to single-girder models, making it suitable for heavy-duty lifting operations.
High Efficiency
Engineered for high performance, this crane offers efficient lifting speeds and smooth travel along its tracks. The robust design and reliable components ensure consistent operation, boosting productivity in demanding environments.
Durable and Reliable
Constructed for longevity, the crane features high-quality materials and components from trusted brands like Schneider for its main electrical parts. This ensures reliable performance and a long service life, even in continuous operation.
Flexible Operation
The crane can be operated via cabin control, ground-based pendant control, or a wireless remote, offering flexibility to match different operational needs and enhance operator safety and visibility.
Application Scenarios
Factory Workshops and Manufacturing
Ideal for lifting and moving heavy machinery, molds, and large components within manufacturing plants and assembly workshops, especially where part of the working area is outside the main building.
Warehouses and Logistics Centers
Excellent for loading, unloading, and transferring heavy goods and containers in logistics hubs. Its ability to operate both indoors and outdoors makes it highly versatile for material handling.
Ports and Docks
Suitable for ship cargo loading and unloading operations, where its robust load-bearing capacity and efficient lifting speed can significantly reduce berthing times and improve throughput.
Outdoor Storage Yards
Perfect for stockyards and open-air storage facilities that handle heavy materials like steel, stone, or precast concrete, providing reliable lifting coverage over a large area.

FAQ
Q: What is the advantage of a semi-gantry crane?
A: A semi-gantry crane saves space and reduces construction costs by utilizing an existing building runway on one side. This makes it an economical and practical solution for facilities that cannot accommodate a full gantry crane but require the lifting capacity and stability it offers.
Q: Is the double girder design necessary for my application?
A: A double girder design is recommended for heavier loads (typically over 10 tons), wider spans, and higher duty cycle requirements. It offers greater stability and lifting height compared to a single girder crane.
Q: Can this crane be customized?
A: Yes, we offer full customization. We can tailor the lifting capacity, span, lifting height, and power supply to meet your specific operational needs and site requirements.
Q: How is the crane controlled?
A: The crane can be configured with several control methods, including a fully enclosed operator’s cabin for maximum visibility, a wired pendant control for ground-level operation, or a wireless remote for greater operator freedom and safety.
Q: What is the typical lead time for delivery?
A: Delivery time is typically within 15-35 days after we confirm your technical requirements and receive prepayment. The exact schedule will be provided with your final order.
