A gantry crane is a type of overhead crane, the differences of which have caused this device to be called a gantry crane. The horizontal bridge connected to the gantry crane is framed on two legs, which also shows the difference between the overhead crane and this device. Apart from this, the gantry crane does not need to be connected to the base like the overhead crane. In fact, there are different types of gantry cranes in the market.
What is a gantry crane?
A gantry crane is kind of like a roof crane, but there are differences that make their names different from each other. These cranes do not need a base for connection, they are available in two types of gantry and semi-gantry cranes in the market, you can choose and buy this device according to the intended use.
Gantry crane
This device, like the overhead crane, is divided into two categories: single bridge and double bridge. The main difference between these two devices is their single bridge and double bridge. In fact, single bridge gantry cranes support a capacity of less than 10 tons and its span is less than 20 meters. But the gantry cranes of the two bridges have a capacity of more than 5 tons and the span is more than 12 meters.
Half gantry crane
If you can operate the crane in the vicinity of a hall, it is possible to operate semi-gantry cranes. Half gantry cranes can only be operated in one column. With the implementation of the half-gantry crane, the crane and the wheels move on the ground. On the other hand, clegi and wheels are placed on the carrier beam. The use of these cranes also helps a lot in reducing costs. It can also be said that it occupies less space, which also saves space.

Advantages of using a gantry crane
As we said, gantry cranes are a type of overhead crane. But this device is supported by independent bases and does its job. These devices are available in different opening capacities and can move heavy weights. The gantry crane is portable, and this feature makes it an economic solution for transporting heavy objects. Such a device is used in freight yards, railways, various warehouses, workshops, etc.
What are the uses of a gantry crane?
Gantry cranes are used in all kinds of places that have heavy loads. For example, we can mention ports, workshops, railways, etc. But if the gantry crane is used in construction workshops, then it can be said that these uses are also included:
1. Helping to close or open the dam valve
2. Carrying out operations such as rail laying
3. Carrying machinery at heights
4. Increasing and developing silos
5. Assembling various prefabricated products (concretes)
Types of gantry cranes
Single bridge gantry cranes:
These structures are usually used to move equipment up to 10 tons in open spaces. Their main advantage is reducing the overall weight of the structure and lower costs compared to the double bridge type. These structures include a bridge, a fixed column, a hinged column, two conductors and two gearbox motors to move on the rails. The transverse movement is performed by the trolley and the lift's transverse movement motor.
Two-bridge gantry cranes:
These types of cranes are usually used to move heavy equipment up to 50 tons in open spaces. These structures are in a higher category than the single bridge type in terms of work class and various capabilities. These structures include two bridges, fixed columns, hinged columns, two guides and a wheel box along with longitudinal motion gearbox motors to move on the rails. Transverse movement is done by a trolley made with transverse motion gearbox motors and a lifting system.
Cost of gantry crane
The price of a gantry crane depends on various factors, just like the price of a overhead crane. The most important factor in the price of the crane is the size and weight of the crane cargo. The size of the crane affects all parts of the crane. The bigger the crane, the bigger the motor and the stronger the tow wire or chain, so the other parts need to be stronger. Another thing that affects the price of a crane is the type of parts and equipment. For example, you can choose a crane housing made of metal or steel, each of which has a fixed price. Another factor affecting the price of a crane is the equipment needed and used in the crane. Many equipment and tools can be used in order to increase safety and quality and... installation in the crane. Cranes are used in various industries such as workshops, steel factories, mines, freight stations, ports, etc.
