Gantry Cranes
Gantry cranes are generally used in open areas where there is no need for an enclosed space, but they can also be used indoors. The design, engineering, manufacturing, and all types of technical services for gantry cranes that can be used in shipyards, rolling mills, businesses serving the iron and steel industry, storage areas, marble companies, industrial facilities in machinery manufacturing, and any business that requires lifting loads is our expertise. Although gantry cranes are often referred to as outdoor cranes or external cranes, there are also applications where they are used indoors.
ARNIKON Engineering, as a result of R&D work, manufactures three types of gantry cranes—single girder, double girder, and semi-gantry—with or without cantilevers (portafo), in compliance with criteria such as DIN standards and FEM standards, using advanced production technologies and processes.

Gantry Crane Systems Features
- Design
- Technology
- Production
- Maintenance & Security
- In Arnikon electric gantry cranes, double speed is provided by a double-speed electric motor. Sensitivity is gained with frequency inverter.
- With motor drivers, namely frequency inverters, both stop & start sensitivity is provided and load safety is achieved.
- With the electric motor and reducer groups specially produced for Industrial gantry cranes, soft starts and stops, impact-free operation and long life are provided.
- The brakes are spring-loaded negative brakes with high torque and 2 times more torque than the maximum capacity.
- Gantry end carriages consist of wheel blocks cast from GGG50 material. These wheel blocks are precisely processed with the latest technology and provide longevity in bearing and wheel life. It also provides a great advantage in reaching the desired high speeds.
- The wheel hub is driven by a multi-wedge system, minimising wear on the wheel hub and drive shaft.
- Remote control of travelling gantry cranes is provided by radio frequency remote control technology.
- Loadcell is used for overload protection.
- All steel materials used are DIN EN 10204 3.1 certified products.
- In Arnikon overhead travelling cranes, double speed is provided by a double-speed electric motor. Sensitivity is gained with frequency inverter.
- With motor drivers, namely frequency inverters, both stop & start sensitivity is provided and load safety is achieved.
- The brakes are spring-loaded negative brakes with high torque and 2 times more torque than the maximum capacity.
- EOT crane end carriages consist of wheel blocks cast from GGG50 material. These wheel blocks are precisely processed with the latest technology and provide longevity in bearing and wheel life. It also provides a great advantage in reaching the desired high speeds.
- The wheel hub is driven by a multi-wedge system, minimising wear on the wheel hub and drive shaft.
- The remote controls of the electrical overhead cranes are provided by radio frequency remote control technology.
- Loadcell is used for overload protection in overhead crane systems.
- All steel materials used are DIN EN 10204 3.1 certified products
- Quality certified sheets are used in the production of gantry cranes and the welds of the produced bridge girders are checked by non-destructive methods and the dimensions are checked according to TS-EN-1090 tolerances.
- All external welds of the bridge beams are welded with submerged arc welding robots.
- Based on the working conditions, we make special primer and paint applications and take precautions against corrosion. We can paint in special colours requested by our customers.
- The cranes can be controlled by push buttons that can move along the beam, as well as by remote control or from the cabin.
- Single or double line C profile cable trolley system can be preferred for the current receiving festoon line along the travelling bridge, and I profile cable trolley system can be preferred for heavy conditions.
- Over-wire electrical installation, closed busbar installation or C profile cable trolley electrical installation can be preferred for the hall length current receiving system.
- All of our gantry cranes are designed in accordance with occupational health and safety standards and procedures.
- Maintenance platform is available in all of our gantry cranes in accordance with the standards.
- Gantry crane legs are equipped with deck ladders for climbing on the crane for maintenance and repair purposes.
- Movement limiting switches are used for all directions.
- Rotary limit switches for crane lowering and lifting movement, cross limit switches for crane trolley and bridge travelling group are available.
- All of the limit switches are double stage in slow down & stop logic.
- Shock absorbing plastic raw material derivative wedges are used at the ends of the crane travelling gear.
- Overload protection, residual current relay, PTC thermistor, collision sensor, emergency stop button, audible/light warning siren are standard protection units in all our gantry systems.
- In addition to the user manual, the electrical diagram and operating manuals of all electrical & electronic components used in the system are delivered to the customer in the crane electrical panel.
What is a Gantry Crane?
A gantry crane, also known as portal crane, are crane model with its own feet. Bridge beams are fixed on these legs. Mostly used in open areas. The most common sectors we come across; shipyards, harbours, mining, machinery manufacturing. Of course, it is not limited to these and can be used in all jobs that require lifting and transporting heavy loads.
Gantry cranes have the same principle as overhead cranes. Since it has its own legs, it does not need an extra construction to get support. With this feature, it is ideal for open areas. It is also very suitable for use in closed areas where it is undesirable to put load on building carriers or there is a need to lift more than the carriers can withstand
Their mobility can be increased up to 3 directions. While it can move back and forth with the rails on the ground to which the feet are connected, it can go horizontally on its own gantry. It also provides lifting by means of hoist.
Parts of a Gantry Crane
We can talk about 6 basic components in the structure of a typical electric gantry crane system. Carrier girders, gantry legs, hoist, ground beam, hook block and end trucks.
Girders and legs form the carrier skeleton of the system. Ground beam is the ground connection on which the crane moves back and forth. It also ensures that it stays on a fixed path. End trucks are the motors that provide the movement of the crane on the ground beam. Hoist and hook block provide the function of lifting the load.
How Long It Takes to Manufacture an Industrial Gantry Crane
Industrial gantry cranes are tailor-made according to the characteristics of the place where they will be used and the needs of the work to be done. Although most dynamics are similar, it is not possible to produce a single model that fits all conditions. For this reason, in order to determine the manufacturing time, it is necessary to first determine the characteristics of the crane to be customly manufactured.
Our gantry crane production process continues with project design after the needs analysis. After the project approval is received by you, the manufacturing phase starts. Manufacturing time varies considerably as it will vary according to the details of the project.
As Arnikon, our main goal is to provide the fastest solutions in the project design and manufacturing stages. Please contact us for detailed information about our manufacturing times.
