8 Similarities And Differences Between Overhead Cranes And Gantry Cranes

In some large construction sites, cranes and other machinery must be used. At present, there are many types of bridge cranes and gantry cranes on the market. Customers choose bridge cranes or gantry cranes according to their own needs, mainly equipment structure, working method, price etc.

What are the similarities and differences between the two types of cranes, gantry cranes and overhead cranes?

Overhead cranes are similar to gantry cranes in that they are used to lift objects for transportation and hoisting. 

1. Both bridge cranes and gantry cranes are powered by electricity.

2. It is possible to work indoors/outdoors with the installation of rain-proof equipment or rain-proof measures.

What is the difference between an overhead crane and a gantry crane?

1. Different appearance

Overhead cranes are like moving bridges.

The gantry crane seems to move the door frame.

2. The structure of bridge crane and gantry crane is different

The two ends of the bridge crane are located on tall concrete columns or metal supports, shaped like a bridge. It consists of main beam, motor, winch, cart walking, trolley walking and so on.

Some of them can use electric hoists, some use winches, the size depends on the actual tonnage.

Overhead cranes are divided into double girder and single girder. (Large tonnage cranes generally use double beams)

The metal structure of the gantry crane is like a door-shaped frame. Two feet are installed under the main beam, which can walk directly on the track on the ground. The two ends of the main beam can have outrigger cantilevers.

It consists of main beam, outriggers, hoist, cart walking, trolley walking, cable drum and so on.

Unlike overhead cranes, gantry cranes have outriggers and can be used both indoors and outdoors.

Notice:

Can overhead cranes be used outdoors?

Overhead cranes can be used outdoors, but are not recommended for outdoor use.

Because there is no outrigger design in its structural design, its support mainly relies on the brackets on the factory wall and the steel rails laid on the load-bearing beams.

3. The operation track is different

Overhead crane is a hoisting machine that is horizontally mounted on the track of the fixed crotch pillar in the building, and is used in workshops, warehouses, etc.

The gantry crane is a variant of the bridge crane, also known as the gantry crane.

On either side of the load-bearing beam there are two tall, large feet that run along the tracks on the road.

4. Different application scenarios

The cable bridge of the bridge crane runs vertically along the tracks paved on the high shelves on both sides, which can flexibly use the indoor space under the cable bridge to hoist raw materials without being blocked by road machinery and equipment. It is a kind of lifting equipment with a wide range of applications and a large number of totals. It is more common in workshops, warehouses and other rooms. It is mainly used in workshops and workshops. heavy equipment.

Gantry cranes work in a variety of ways, usually small tonnage indoors, shipbuilding gantry cranes and container gantry cranes outdoor are large tonnage lifting equipment, and container gantry cranes are used for port lifting. This gantry crane adopts a double cantilever structure.

It is mainly used for open-air operations, such as the loading and unloading of outdoor cargo yards, stockyards, and bulk cargoes.

5. Equipment prices vary

Compared with the gantry crane, the price of the bridge crane is slightly lower, and there are many factors that affect the price: manufacturers, raw materials, exchange rates, etc., will have a certain impact on the price.

Note: Although there is a certain price difference between bridge cranes and gantry cranes, when making choices, be sure to choose according to different working environments and needs.

6. Features are different

Bridge crane: The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machinery.

The high-level bridge cranes are generally metallurgical cranes, casting cranes, electromagnetic cranes, etc. This type of bridge cranes have higher working levels and relatively low energy consumption.

Gantry crane: It has the characteristics of high site utilization rate, large operating range, wide adaptability and strong versatility, and is widely used in port cargo yards.

The working level of gantry cranes is generally A3, which is for general gantry cranes. For large-tonnage cranes, the working level of customers with special requirements can be raised to A5 or A6, and the energy consumption is relatively high.
