Gantry Cranes

What is Gantry Crane?

Gantry crane is a type of crane that is mostly preferred for load carrying in open and closed areas, where the bridge beams are fixed on the portal legs and the portal legs move on the walkway rails fixed to the ground with the bridge walking group.

Large and heavy loads can be transported more comfortably and safely with our gantry crane systems compared to bridge cranes. It also reduces unused space and provides optimum utility in the field.

Gantry cranes, which can move without the need for any building structure, can perform independent or dependent lifting operations, and also provide various advantages to the user with single beam or double beam options and right/left portafo system.

Additionally, semi-gantry cranes combine the benefits of overhead cranes and full gantry systems, allowing partial support from one side while minimizing footprint, particularly useful in tight spaces. Another notable type is the rubber-tired gantry crane, frequently employed in container yards and logistics hubs, offering mobility and flexibility over fixed-rail systems.

Each type is designed with a focus on load capacity, span, and operational environment, ensuring that whether for indoor warehouses, outdoor shipyards, or heavy manufacturing sites, there is a gantry crane perfectly suited to handle material movement safely and efficiently.

Innovations in automation and electric hoists have further expanded the functionality of gantry cranes, making them indispensable in modern industrial logistics.

What is Semi Gantry Crane?

Cranes that move on the walkway rail fixed on the ground on one side and on the walkway rail fixed on the building on the other side are called semi-gantry cranes.

What is Portable Gantry Crane?

Portable gantry cranes are used to lift and move smaller objects, typically less than 10 tonnes (9.8 long tons; 11 short tons).

How is Gantry Crane Made?

The construction of gantry cranes starts with the general view drawings to be made in line with the project, dimensions and user demands of the facility or area where the crane will be used. Portal cranes, steel construction bridges are designed and manufactured to have a deflection rate of L/1000.

In line with the customer's request, extension consoles can be made from the rail axis to the right and left sides. These consoles are called portafo. While designing the portafo, it may be necessary to make a counterweight so that the center of gravity stays between the two legs.

Counterweights can be placed on the crane as well as by filling the inside of the feet. FEM/ISO values ​​are determined in line with the working conditions of the enterprise requesting gantry cranes, and the designs are manufactured accordingly.

After the portal crane is manufactured as a result of user demands, project and measurement information, and measurements made by Asan Cranes expertise, it is assembled in its place by the expert technical team.

The load carrying capacities of the ropes vary according to the rope diameters and the construction characteristics of the ropes. While the rollers used in the portal crane enable the load to change direction, the hook blocks are used as load lifting devices. The part where the load is attached to the hanger is called the sling.

The load carrying capacity of the sling varies with the knotting pattern and the angle of the arm, and the angle of the sling also changes with the knotting method, such as single and double. Cross bars, clamps, suspension rings, etc. The correct and synchronized use of fasteners ensures safe delivery of the load to the destination.

Where is Gantry Crane Used?

Gantry cranes, which can move without the need for any building structure, are used in industrial manufacturing factories, workshops, open field stockpiles, container stock areas, hydroelectric power plants, dams, ports, railways, marble manufacturers, stockpiling warehouses, etc. Gantry cranes are used in the sectors.

Portal Cranes Design

Portal cranes are in line with the demands of the companies; It is designed and manufactured according to the desired lifting heights and can move in 3 axes and 6 directions. Steel construction bridges are designed to have a deflection rate of L/1000. Asan Cranes designs gantry cranes with its experienced engineer staff consisting of R&D and project engineers.

Portal Cranes Dimensions

Portal cranes; portal, semi-portal and portable portal consists of three groups. Gantry cranes can be produced by Asan Cranes for gantry cranes with rubber wheels, as well as systems that generally walk on rails.

Field width and length are important when taking portal crane dimensions. In addition, the height of the load to be lifted and the height in the carrying area, plus the min. Lift height is determined. In deep well gantry cranes, the well depth should also be added.

How Is a Gantry Crane Installed?

The installation of a gantry crane is carried out by Aşan Vinç’s expert and highly experienced technical team. After the gantry crane components are matched, the paired parts are assembled, and once the structure is completed, the hoist (trolley) is mounted onto the crane. During installation, the gantry crane—initially assembled in a horizontal position—is raised to an upright position using a Hiab truck crane or a mobile crane.

After the installation is complete, the gantry crane travel wheels are checked. Otherwise, deformations that may occur while lifting can cause binding during crane movement. Once the setup is finalized, all components are run without load to ensure proper operation.

Next, a dynamic test is performed with 110% of the rated capacity, followed by a static test with 125% of the capacity. After load tests are completed, switch inspections and load cell capacity calibration are carried out according to the required capacity, and the crane is then delivered to the customer.

Installing a gantry crane involves several steps. Here is a general outline of the process:
