Difference Between Overhead Crane and Gantry Crane

A overhead crane is a type of crane that runs on an elevated track. Its lifting trolley runs horizontally along the track, making full use of the space under the overhead crane to lift materials without being hindered by ground equipment. A gantry crane is a variation of a overhead crane. The following points can be used to distinguish between bridge and gantry cranes:

• Structure of Cranes

Overhead Crane Structure:

The structure of a overhead crane is divided into a steel structure, a mechanical transmission part, and an electrical part. The steel structure consists of a bridge frame and a trolley frame, and the bridge frame consists of main beam, end beam, platform, guardrail, and operating room. The trolley consists of frame and rail. The mechanical transmission part consists of trolley running mechanism and lifting mechanism. The electrical part consists of electrical lines and electrical equipment.

Gantry Crane Structure:

Gantry crane is generally a lifting equipment with a door-like frame structure, with legs installed under the main beam and walking mechanism. It can travel directly on the ground track, and both ends of the main beam have an outrigger cantilever beam. Gantry crane consists of main beam, outrigger cantilever beams, rails, trolley running mechanism, and electrical part.

• Running Tracks

Overhead crane is a lifting equipment that is horizontally mounted on a track between fixed pillars of a building and is used in workshops, warehouses, etc. for loading and unloading and lifting and handling indoors or outdoors.

Gantry crane is a variation of a bridge crane, with two tall legs at either end of the main beam running along tracks on the ground.

• Different Application

The bridge of the overhead crane runs longitudinally along the tracks laid on the elevated platforms 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 a kind of lifting machinery with a wide range of uses and a large number of uses, and is more common in workshops, warehouses and other indoor places.

Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. Therefore, gantry cranes are widely used in indoor and outdoor scenes such as port cargo yards where there are no conditions for erecting steel structures.
