What is the difference between gantry crane and overhead crane?

There are many differences between gantry cranes and bridge cranes. The following takes double girder bridge cranes and double girder gantry cranes as examples.

Difference 1: Different appearance

1. Overhead crane (shaped like a moving bridge)

2. Gantry crane (looks like a door frame that moves)

Difference 2: The running track is different.

1. The overhead crane is a lifting equipment 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. There are two tall legs at both ends of the main beam, which run along tracks on the ground.

Difference 3: different scenarios are applied.

1. The bridge frame of the overhead crane runs longitudinally along the tracks laid on both sides of the elevated frame, 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 applications and a large number, and it is more common in workshops, warehouses and other indoor areas.

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

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