What is the difference between a gantry crane and a regular crane

Portal crane, also known as gantry crane, is a heavy lifting equipment with a unique portal structure, widely used in various industrial and construction occasions. The following is a detailed explanation of gantry cranes compiled by Shandong gantry crane manufacturers and their differences from ordinary cranes:

1、 Definition and characteristics of gantry crane

definition:

A gantry crane is a type of gantry crane that operates in a cyclic and intermittent motion. Its metal structure resembles a portal frame, with two support legs installed under the main beam, allowing it to walk directly on the ground track. The main beam can have outward overhanging cantilever beams at both ends.

characteristic:

1. Structural stability: The main beam and leg support structure of the gantry crane are stable and can withstand large lifting loads.

2. Wide range of operations: Due to its unique portal structure, gantry cranes have a large span capacity and operating range.

3. Strong adaptability: Portal cranes are suitable for various working environments, such as open-air warehouses, docks, metallurgy, power, chemical and other industrial sites.

4. Strong universality: Portal cranes can meet different lifting needs by replacing different crane structures.

2、 The difference between gantry crane and ordinary crane

1. Structural form:

Portal crane: It has a unique portal structure and is equipped with two legs under the main beam, allowing it to walk directly on the ground track.

Ordinary cranes: There are various structural forms, such as bridge cranes, cantilever cranes, tower cranes, etc., which may not necessarily have a portal structure.

2. Scope of assignment:

Portal crane: Due to its portal structure and large span capacity, the operating range is relatively large.

Ordinary crane: The operating range may be relatively small due to its own structure and installation location limitations.

3. Applicable occasions:

Portal crane: more suitable for occasions that require large spans and lifting capacity, such as open-air warehouses, docks, etc.

Ordinary crane: suitable for various industrial and construction occasions, but the specific applicable occasions need to be determined according to its type and performance.

4. Functional features:

Portal crane: usually has a large lifting capacity and a wide operating range, which can meet the needs of handling and loading and unloading large items.

Ordinary cranes: The functional characteristics vary depending on the type, but generally do not have the portal structure and large crossing capacity of gantry cranes.
