What are the similarities and differences between bridge cranes and gantry cranes?

Bridge cranes and gantry cranes are the second-level classifications of bridge type cranes and boom type cranes. There are more specific subdivisions below them, and the styles, performance and other aspects are very different. Due to space limitations, it is inconvenient to compare here one by one, so I will select the most used typical equipment for review, hoping to improve everyone's understanding of hoisting machinery.

Here is an example of double girder bridge crane and double girder gantry crane

1. Similarities

It can be applied to the working environment of indoor lifting and hoisting, most of which are driven by electric power. When rainproof equipment or rainproof measures are installed, it can be operated outdoors.

Two, the difference

as follows:

Difference 1: Different appearance.

1. Bridge crane (shaped like a moving bridge)

2. Gantry crane (looks like a moving door frame)

Difference 2: The running track is different.

1. The bridge crane is a lifting device that is horizontally framed on the track of the fixed crotch pillar of the building and is used in workshops, warehouses, etc., indoors or in the open air for loading, unloading, and lifting.

2. Gantry crane is a variant of bridge crane, also known as gantry crane. There are two tall legs at both ends of the main beam, which run along tracks on the ground.

Difference three: different scenarios are applied.

1. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated bridges on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with a wide range of use and a large number, and it is more common in workshops and warehouses.

2. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards.

To sum it up in one sentence, the door style has its own legs and the wheels are on the ground (the rails are laid on the ground); the bridge style is in mid-air, the wheels are on the beams of the pillars (the beams are laid on the beams), and the beams are erected on the supports extended from the pillars ( Horns) on.
