What is a Gantry Crane?

A gantry crane is a type of overhead crane supported by freestanding legs that run on rails or a track system. It consists of a bridge structure (single girder or double girder) equipped with a hoisting trolley for lifting and moving materials.

Gantry cranes are available in a wide range of lifting capacities, from light-duty models to heavy-duty systems exceeding 500 tons with customized designs. They provide an efficient and cost-effective solution for handling loads of different sizes, weights, and shapes in various industrial applications.

Unlike traditional overhead cranes that require a building support structure, gantry cranes are commonly installed in outdoor areas such as yards, puertos, astilleros, y sitios de construcción. They can also be used indoors in factories, talleres, almacenes, e instalaciones de mantenimiento.

As a professional gantry crane manufacturer, we provide complete solutions including crane design, engineering, fabrication, installation support, and technical services. Our gantry cranes are widely used in shipbuilding, steel production, machinery manufacturing, logística, material storage, and other industries requiring reliable heavy lifting solutions.

Main Types of Gantry Cranes & Comparison

Gantry cranes come in a variety of types and styles, varying with different loads and lifting capacities. Due to diverse shapes and sizes, gantry cranes can be used in a variety of industrial applications. The distinction between types of gantry cranes is determined by crane girder configuration, crane size, and hoisting trolley, etc..

Gantry cranes are classified into different types based on configurations, designs, and lifting capacity, which are interacted in a variety of ways to define the type of gantry crane for the specific applications.

Full Gantry Crane

A full gantry crane is the most common type of gantry crane, consisting of a bridge girder, two supporting legs, carros finales, and a hoisting system. The crane runs on ground-mounted rails or tracks and is widely used for outdoor and indoor material handling applications.

Depending on the working environment and project requirements, full gantry cranes can be designed with electric hoists, winch trolleys, rubber tires, or rail-mounted traveling systems.

Semi Gantry Crane

A semi gantry crane combines the features of an overhead crane and a gantry crane. One side of the bridge girder is supported by a ground-level leg, while the other side runs on an elevated runway system attached to the building structure.

This design helps save installation space and is suitable for workshops, almacenes, and production facilities where only one side requires ground support. Semi gantry cranes are often used together with overhead cranes to improve material handling efficiency.

Portable Gantry Crane

Portable gantry cranes are lightweight and flexible lifting solutions equipped with movable wheels or casters for easy relocation. They are available in steel and aluminum designs, with lifting capacities typically ranging from 500 kilogramos a 10 montones, and customized designs available for higher capacities.

Portable gantry cranes are ideal for maintenance, equipment installation, talleres, and occasional lifting operations where a permanent crane system is not required.

Adjustable Gantry Crane

Adjustable gantry cranes are designed with adjustable height, width, or beam configurations to accommodate different lifting requirements. They can be designed as portable or fixed systems depending on the application.

With their flexible structure and easy adjustment, adjustable gantry cranes are widely used for maintenance work, machinery installation, and general material handling.

Grúa pórtico monorraíl

A single girder gantry crane features one main bridge beam with a hoist trolley running along the girder. It is a cost-effective lifting solution commonly used for light and medium-duty applications.

The main components include the bridge girder, carros finales, supporting legs, traveling mechanism, controles de grúa, and electric hoist. Depending on the application, single girder gantry cranes can be designed as full gantry cranes, semi gantry cranes, or customized configurations.

Grúa pórtico de doble viga

A double girder gantry crane consists of two parallel bridge girders and is designed for heavy-duty lifting applications. It offers higher load capacity, larger spans, and better stability compared with single girder models.

Double girder gantry cranes can be equipped with top-running or under-running trolley systems and are widely used in steel plants, astilleros, puertos, precast concrete yards, and heavy manufacturing industries.

Typical lifting capacities range from 3 toneladas a 550 montones, with customized designs available including A-frame and U-frame leg structures.

Truss Gantry Crane

A truss gantry crane features a lightweight truss-type main girder structure instead of a conventional box girder. The trolley typically travels on the top of the truss girder, and a driver’s cabin can be provided for operator control.

Due to its lightweight design and reduced wheel loads, truss gantry cranes are suitable for applications requiring long spans, outdoor operation, and reduced foundation requirements.

L-Shaped Gantry Crane

An L-shaped gantry crane is a single-girder gantry crane equipped with L-shaped supporting legs. This structure provides more open space beneath the crane, making it suitable for handling long and oversized loads.

L-shaped gantry cranes are commonly used in freight yards, railway terminals, almacenes, and outdoor storage areas. Typical capacities range from 5 toneladas a 32 montones, with optional features such as soft-start traveling systems for smoother and more stable crane movement.
