Single Girder Gantry Crane L-Type

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.

Feature&Advantages

Economical Structure: The L-shaped design results in a lower overall height for the same lifting height, making it suitable for factories with height restrictions or saving on construction costs.

Lightweight: Compared to double-girder structures, single-girder gantry cranes are lighter, placing less wheel pressure on the ground and reducing civil engineering costs.

Good Maneuverability: The single-girder structure offers structural advantages when lifting long goods across spans without being limited by outrigger space.

Application

Open-air freight yards: Loading, unloading, and stacking of goods such as steel, timber, stone, and containers.

Railway lines: Loading and unloading of goods from train carriages.

Port terminals: Assisting other equipment in loading and unloading ships or vehicles (light-duty).
