Description
Weihua L-type single-girder gantry cranes are customized lifting equipment specifically designed for outdoor light and medium-sized material handling, widely used in open-air freight yards, railway lines, ports, and docks. While ensuring reliability, this product achieves three core advantages through its innovative L-shaped outrigger structure: reduced overall height, lighter weight, and cost savings.
The L-type single-girder gantry crane is one of the most widely used members of the gantry crane family, named for its unique inverted "L"-shaped outrigger structure. As a rail-mounted medium-to-large-sized lifting equipment, it perfectly integrates the lightweight advantages of a single-girder structure with the ingenious design of the L-shaped outriggers in terms of overall height. It is mainly suitable for various outdoor operation scenarios with lifting capacities between 5 and 50 tons, spans between 10 and 35 meters, and lifting heights between 6 and 30 meters. This equipment plays an indispensable role in many key industries such as machinery manufacturing, metallurgy, mining, power construction, railway transportation, ports, and petrochemicals, serving as a core material handling tool connecting production, warehousing, and transportation. It must withstand harsh outdoor environments exposed to wind and sun, and meet the demands of high-intensity loading and unloading operations. Therefore, its design concept, structural features, and functional configuration all revolve around three core elements: "economical and practical, reliable and durable, and highly adaptable."
Weihua L-type single-girder gantry crane is a customized product. The final price and specific configuration depend on the lifting capacity, span, lifting height, control method, and the selection of electrical components (such as whether to use frequency converter control). If you have specific tonnage and span requirements, you can obtain a more precise quote and technical solution.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Space-Efficient L-Shaped Leg Design
The L-shaped leg structure creates a low overall height while maintaining the lifting height, reducing the crane's total construction cost and spatial footprint . This design enables efficient operation in spaces where an A-type or double-girder crane would be impractical.
High Site Utilization & Load Clearance
The single-beam offset track design allows the hoist to transfer objects from within the span to outside the rail centers . This maximizes site utilization and provides clear passage for long cargo, with the main beam optionally extending to one or both sides as a cantilever to expand the working range.
Lightweight & Cost-Effective Construction
With a welded box-type or truss-style single girder structure, the crane weighs significantly less than double-girder alternatives . This reduces wheel pressure and lowers foundation investment, while the simple manufacturing process ensures quick installation and lower maintenance costs.
Flexible Operation & Control
The crane supports multiple control methods including pendant push-button, wireless remote control, or cabin operation . Standard features include overload protection, low-voltage protection, and limit switches, with optional variable frequency drive
