Product Introduction
A Truss Gantry Crane is a type of gantry crane designed with a truss structure main girder instead of a traditional box girder. The truss structure is usually made of welded steel plates, angle steel, channel steel, round tubes, or square tubes. Due to its open web design, the truss gantry crane has the advantages of lighter self-weight, lower wind resistance, convenient transportation, and stable lifting performance, especially for outdoor lifting applications.
Compared with box girder gantry cranes, truss type gantry cranes are often selected for outdoor yards, construction sites, precast concrete yards, hydropower projects, road and bridge construction, steel structure fabrication yards, and material storage areas where wind load, transportation convenience, and cost efficiency are important considerations.
ZOKECRANE truss gantry cranes are designed and manufactured by Henan Zoke Crane Co., Ltd., a professional lifting equipment manufacturer specializing in overhead cranes and gantry cranes. Our manufacturing base is located in Changyuan, Henan Province, one of China’s major crane production centers. With extensive experience in crane engineering, design, manufacturing, and quality control, ZOKECRANE provides practical and customized truss gantry crane solutions for international customers.
The truss gantry crane is generally composed of a truss main girder, support legs, lower end beams, crane traveling mechanisms, trolley or electric hoist, lifting mechanism, electrical control system, power supply system, and safety protection devices. According to different lifting requirements, it can be designed as a single girder truss gantry crane, double girder truss gantry crane, rail mounted truss gantry crane, semi gantry crane, or portable truss gantry crane.
This type of crane is suitable for lifting and transferring steel bars, steel structures, precast concrete components, pipes, formwork, molds, construction materials, machinery parts, and other medium or heavy materials. ZOKECRANE can customize the crane according to lifting capacity, span, lifting height, cantilever length, rail length, working duty, outdoor environment, wind load requirements, power supply, control method, transportation size, and destination country requirements.

Applications of Truss Gantry Crane
The truss gantry crane is widely used in outdoor and semi-outdoor lifting operations. Because of its truss structure, lighter self-weight, and lower wind resistance, it is particularly suitable for large outdoor working areas and long-term material handling projects.
Construction Sites
At construction sites, truss gantry cranes are used to lift and transfer construction materials, steel bars, formwork, prefabricated parts, machinery components, tools, and structural materials. The crane can improve lifting efficiency and reduce manual handling risks.
Precast Concrete Yards
In precast concrete yards, truss gantry cranes are used for handling precast beams, concrete slabs, wall panels, molds, columns, and other prefabricated components. The crane can be customized with suitable span, lifting height, working duty, and outdoor protection devices.
Road and Bridge Construction
Truss gantry cranes can be used in road and bridge construction projects for lifting bridge beams, steel structures, formwork, construction modules, and reinforcement materials. For special bridge construction applications, the crane structure can be customized according to project requirements.
Steel Structure Fabrication Yards
In steel structure fabrication yards, truss gantry cranes are used for lifting steel plates, steel sections, welded beams, truss components, pipes, steel frames, and fabricated modules. The crane can be equipped with hooks, lifting beams, clamps, or magnets according to the materials being handled.
Outdoor Storage Yards
Truss gantry cranes are suitable for loading, unloading, stacking, and transferring materials in outdoor storage yards. Their relatively low wind resistance makes them practical for open-air environments.
Hydropower and Infrastructure Projects
For hydropower stations, dam construction, and infrastructure projects, truss gantry cranes can support the lifting of construction materials, machinery parts, steel structures, gates, pipes, and maintenance components.
Machinery Manufacturing and Assembly Areas
Truss gantry cranes can also be used in machinery manufacturing plants and assembly areas for lifting equipment parts, frames, molds, and large components.
Temporary or Project-Based Lifting Operations
Because the truss structure can be manufactured in sections and transported more conveniently, truss gantry cranes are often used for temporary construction projects, remote sites, and project-based lifting operations.

Frequently Asked Questions About Truss Gantry Crane
1. What is a truss gantry crane?
A truss gantry crane is a gantry crane with a truss structure main girder. Compared with a box girder design, the truss structure has an open web form, which can reduce wind resistance and may reduce self-weight in suitable designs. It is commonly used for outdoor lifting operations.
2. What is the difference between a truss gantry crane and a box girder gantry crane?
The main difference is the structure of the main girder.
A truss gantry crane uses an open truss structure made of steel plates, angles, channels, or tubes. It has lower wind resistance and is often suitable for outdoor use.
A box girder gantry crane uses a closed box-type girder. It usually has higher torsional rigidity and is widely used for heavy-duty industrial applications.
The suitable design depends on lifting capacity, span, working duty, wind load, site conditions, and budget.
3. Is “Truss Gantry Crane” or “Truss Type Gantry Crane” more commonly used?
Both names are understandable and commonly used. However, Truss Gantry Crane is shorter and more suitable for product titles, SEO keywords, and product categories. Truss Type Gantry Crane is useful in product descriptions and technical explanations.
4. What lifting capacity can ZOKECRANE provide?
Common lifting capacities include 3 ton, 5 ton, 10 ton, 16 ton, 20 ton, 32 ton, and 50 ton. Larger or special capacities can be customized according to working requirements, structure type, span, lifting height, and application.
5. Can the truss gantry crane be used outdoors?
Yes. Truss gantry cranes are very suitable for outdoor applications. For outdoor use, ZOKECRANE can provide windproof devices, rail clamps, anchoring systems, rain covers, outdoor electrical protection, anti-corrosion painting, anemometers, warning lights, and alarms.
