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.
Asan Vinc gantry cranes are built for simplicity and maximum usability. With their specially designed steel structures, they are ideal for different types of buildings and work areas, both indoors and outdoors.
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.
Portable gantry cranes are used to lift and move smaller objects, typically less than 10 tonnes (9.8 long tons; 11 short tons).
Gantry cranes are manufactured from 2 tons to 500 tons in accordance with FEM, DIN and TSE / EN norms with domestic and imported equipment, standard and special type lifting groups, at desired lifting heights, as single speed, double speed or stepless speed.
Gantry cranes are with pendant button control as standard, and are also offered with remote control or cabin control upon request. It also contributes to the professional working environment brought about by being remotely controllable. Thanks to the sudden braking system, the stopping feature also reveals its functional structure and safety.
In places where the wind speed is high, wind locks are made and the gantry crane is automatically locked in bad weather conditions. It can work in humid and rainy environments as well as in chemical environments. It can work even in high temperature or cold environments down to -40°C.
Crane bridge beams of our standard tonnage gantry cranes are manufactured from box type construction, and we also manufacture truss type beams upon customer request. The maintenance platform, which provides ease of maintenance and assembly on the crane bridge, is available in all our gantry cranes.
Installing a gantry crane involves several steps. Here's a general outline of the process:
1. Assess the requirements: Determine the lifting capacity, span, and height needed for your gantry crane. Consider factors such as the type of load, the available space, and any specific requirements.

4. Prepare the site: Clear the area where the gantry crane will be installed, ensuring there's sufficient space for its movement and operation. Verify that the ground is level and capable of supporting the crane's weight.
5. Install supporting structure: Erect the structural components necessary to support the gantry crane, such as the legs or uprights and the overhead beam. Ensure proper alignment and secure the structures according to engineering specifications.
6. Assemble the crane: Follow the manufacturer's instructions to assemble the gantry crane components. This typically involves attaching the cross beams, trolley, hoist, and other relevant parts. Use appropriate tools and equipment to ensure proper installation.
7. Electrical and mechanical connections: Connect the electrical wiring and controls required for the gantry crane's operation. Coordinate with qualified electricians to ensure safe electrical connections. Install any mechanical components needed for functionality, such as limit switches or safety devices.
8. Perform load testing and inspections: Once the gantry crane is assembled, conduct load testing to ensure it operates smoothly and safely. Perform thorough inspections to check for any defects or issues that need to be addressed before the crane is put into service.
9. Training and certification: Train personnel who will operate the gantry crane, ensuring they understand its controls, safety features, and operating procedures. Obtain any required certifications or licenses for crane operators, if applicable.
It's crucial to note that installing a gantry crane is a complex task that requires expertise and adherence to safety standards. Therefore, it's recommended to consult with professionals or gantry Asan Cranes who can guide you through the installation process based on your specific requirements.
Aşan Vinc offers economical solutions in automation, special production and special capacity gantry crane systems as in standard gantry crane manufacturing. All design, projecting, production and after-sales services of gantry cranes belong to our company.
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 Aşan Vinc expertise, it is assembled in its place by the expert technical team.
Gantry cranes; With the command of the operator, it moves in 3 axes and 6 directions as right, left, up, down, forward and backward on the area where it is placed. While the electronic system activates the machine, the remote control is used to direct the load. The control of the crane can be done with the help of the arms inside the cabin, as well as with the wired control or wireless remote control controls. In portal cranes, loads are lifted with steel ropes.
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.
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 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. Aşan Vinc designs gantry cranes with its experienced engineer staff consisting of R&D and project engineers.
Portal cranes; portal, semi-portal and portable portal consists of three groups. Gantry cranes can be produced by Aşan Vinç 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.
Installation of gantry crane; It is carried out by Aşan Vinc's expert and experienced technical team. After the gantry crane parts are matched, the matched parts are mounted together and after the crane is installed, the lifting machine (cat) is mounted on the crane. The gantry crane, which is installed horizontally during installation, is brought to an upright position with the help of hiyap (Hi-Up) or mobile crane.
Gantry crane walking wheels are checked after the product installation is finished. Otherwise, the distortions that may occur during lifting may cause contraction in the crane movement. After the installation is done, all parts are run without load and it is ensured that they are working.
Then, dynamic test with 110% capacity load and static test with 125% capacity load are performed. After the load tests, switch controls and loadcell capacity adjustment are made according to the capacity and delivered to the customer.
Axle clearance, lifting capacity and lifting height are the main features that determine the prices of gantry cranes.
