A Single Girder Gantry Crane is a cost-effective and versatile lifting solution designed for light to medium-duty material handling. It features a single main girder supported by gantry legs running on ground rails, enabling efficient lifting and horizontal movement without relying on building structures. This type of gantry crane is widely used in outdoor yards, workshops, warehouses, and prefabrication areas where flexible installation and stable performance are required.
Single-girder gantry cranes have a compact structure, a small footprint, and maximize the use of vertical lifting space. Their design typically incorporates a standard electric hoist running along the lower flange of the single beam, allowing for a greater hook approach range and higher lifting height. Furthermore, their simple installation and easy maintenance reduce long-term operating costs for various industrial applications.
Single-girder gantry cranes are lightweight lifting equipment widely used in both indoor and outdoor settings. They primarily consist of a main girder, outriggers, a lower crossbeam, a hoisting mechanism (electric hoist), and a traveling mechanism. Common types are primarily distinguished by outrigger configuration and operating environment, including semi-gantry cranes, L-shaped single-girder gantry cranes, box-type structures, and truss-type structures. These variations accommodate diverse site conditions, lifting heights, and load requirements.
Below are several common types of single-girder gantry cranes, which differ in structural design, application scenarios, and advantages. Weihua Crane can provide customized designs based on specific customer requirements.
The main girder of Single Box Girder Gantry Crane features a box-type cross-section, offering excellent rigidity and high load-bearing capacity. It is commonly paired with CD/MD Electric Wire Rope Hoists or European-style hoists. The outriggers typically adopt a rigid box-type structure. High load capacity, stable structure, and aesthetically pleasing design make it suitable for indoor use or locations with high appearance requirements, such as large workshops, cargo yards, and ports. Easy maintenance and configurable with multiple functionalities.
The main girder of the Single Girder Grúa Pórtico de Armadura adopts a truss structure, fabricated by welding structural steel (such as angle steel and channel steel) to form a triangular grid pattern. This design offers a lightweight structure with low self-weight, strong wind resistance, and lower manufacturing costs. It is particularly suitable for outdoor work sites and areas with high wind speeds, such as open-air cargo yards and railway freight stations, effectively reducing the load on foundations and tracks.
El Single Girder Grúa semiafalcada operates with one side of its legs running on ground rails, while the other side runs on workshop corbel beams or wall rails. It offers significant space savings, making it particularly suitable for work areas adjacent to walls or columns, allowing for optimal utilization of building space. It provides greater operational flexibility and features relatively lower investment costs.
The L-type single girder gantry crane features L-shaped legs, with the lifting mechanism cantilevered on the inner side of the L-shaped legs. Its structural design allows for easier passage of goods directly from one side of the span, offering a unique advantage for lifting large or extra-long loads, thus improving working space and efficiency. It is commonly used in open-air warehouses and storage yards.
Single-girder travelling gantry cranes are a vital type of lifting and transport equipment, primarily composed of two major sections: the metal structure and the mechanical transmission system. Below is an introduction to several key components of single-girder gantry cranes and it’s characteristics:
The working principle of a Single Girder Travelling Gantry Crane is based on coordinated lifting and traveling movements driven by electric systems. The electric hoist travels along the main girder to achieve cross movement, while the hoisting mechanism lifts and lowers the load vertically through a wire rope and hook system. Simultaneously, the gantry traveling mechanism drives the crane along ground rails to enable longitudinal movement. All motions are controlled via an electrical control system, ensuring smooth operation, precise positioning, and safe handling of materials within the rated load capacity.
Hoist single girder gantry cranes are typically equipped with electric hoists as the primary lifting mechanism, which determines the crane’s performance and load capacity. The selection of lifting devices depends on the shape and characteristics of the cargo being transported.
Weihua Crane offers customized designs, flexibly combining the most suitable electric hoist and specialized lifting gear based on the customer’s rated load capacity, duty cycle, lifting speed, and material characteristics to maximize crane operational efficiency and safety. Below are common hoist types and their features:

A: The primary differences lie in load capacity and structural complexity. Single-girder gantry cranes feature simpler structures, lighter self-weight, and lower costs. They are suitable for applications with smaller lifting capacities (typically 3t to 20t), lower duty cycles (A3 to A5), and moderate spans. Double-girder gantry cranes offer greater load capacity and higher stability, making them ideal for heavy-duty applications requiring large lifting capacities, high duty cycles, and greater lifting heights. Your selection should be based on rated load capacity and operating frequency.
A: Weihua provides two primary types: box structure and truss structure. Box Type: Offers high rigidity and an aesthetically pleasing appearance, suitable for indoor environments or locations with stringent aesthetic requirements.
Truss Type: Features low self-weight, strong wind resistance, and lower manufacturing costs, making it ideal for outdoor yards, windy regions, and environments with strict foundation requirements.
A: Installation duration typically depends on crane dimensions and site readiness, generally completed within 3 to 7 working days. Site requirements include level ground track foundations meeting load-bearing specifications, sufficient installation space (crane hoisting area), and adequate safety clearance. Track foundation design must strictly adhere to load data provided by the crane manufacturer.
A: Key parameters affecting the quote include: rated lifting capacity (Q), span (S), lifting height (H), duty class (A), and hoist type (standard wire rope/European/chain). European hoists and higher duty class configurations significantly increase costs. Cost budgeting should first determine these four core parameters while accounting for transportation costs, installation fees, and customization options.
A: Routine maintenance should include inspecting wire rope wear and broken strands, brake reliability, lubrication status of running mechanisms, and wheel wear. Safety inspections must include regular no-load and rated-load tests. Critical wear components—including wire ropes, brake linings, wheel treads, and gearbox lubricants—require periodic replacement or maintenance per the manufacturer’s manual.
