What is the difference between gantry crane and overhead crane

There are significant differences between gantry cranes and bridge cranes in multiple aspects. The following is a comparison of the two by Shandong gantry crane manufacturers:

1、 Structural form

1. Dragon Gate Crane:

The metal structure is like a portal frame, with two support legs installed under the main beam.

The main beam can have overhanging cantilever beams at both ends, and the support legs can directly walk on the ground track.

2. Bridge crane:

Also known as a crane, its structure consists of a bridge frame, a lifting trolley, a large vehicle operating mechanism, and electrical equipment.

The two ends of the bridge are located on tall cement columns or metal supports, shaped like a bridge.

The bridge runs longitudinally along the tracks laid on both sides of the elevated platform, which can fully utilize the space under the bridge to lift materials.

2、 Running trajectory

1. Dragon Gate Crane:

Due to its high utilization rate and wide operating range, it usually walks directly on the ground track.

2. Bridge crane:

The bridge runs longitudinally along the tracks laid on both sides of the overhead structure, while the crane trolley runs laterally along the tracks laid on the bridge, forming a rectangular working range.

3、 Application scenarios

1. Dragon Gate Crane:

Mainly used for loading and unloading operations in outdoor freight yards, material yards, and bulk cargo.

It is widely used in port cargo yards due to its characteristics of large operating range, wide adaptability, and strong versatility.

2. Bridge crane:

Widely used in indoor and outdoor warehouses, factories, docks, and open-air storage yards.

It can fully utilize the space under the bridge to lift materials without being obstructed by ground equipment.

4、 Appearance and Features

1. Dragon Gate Crane:

The appearance resembles a movable door frame, with a stable structure and high wind resistance.

2. Bridge crane:

Shaped like a bridge, with both ends resting on tall supports, the structure is relatively complex but stable.

In summary, there are significant differences between gantry cranes and bridge cranes in terms of structural form, operating trajectory, application scenarios, and appearance characteristics. These differences enable both to achieve optimal performance and effectiveness in their respective fields of application.
