Diferencias entre grúas pórtico y grúas de astillero

Is there any difference between a gantry crane and a shipyard crane?

First of all, grúas de astillero Sevencrane is also called gantry crane. It is mostly used for loading and unloading operations in outdoor cargo yards, material yards, and bulk cargoes. Its metal structure is like a door-shaped frame, with two legs installed under the main beam, which can walk directly on the track on the ground. There are overhanging cantilever beams at both ends of the main beam. The overall gantry crane has the characteristics of high site utilization, wide adaptability, large operating range, and strong versatility, and has been widely used.

Secondly, grúas de astillero are cranes specifically used for ship manufacturing in shipyards. It generally runs along ground tracks, and ships can be placed underneath. The four legs of the portal frame form four “door openings”, which can be used to store boats in the water tank below. Shipyard cranes mostly run along crane tracks on the ground or on buildings to complete shipbuilding operations.

1. Different functions
1. Industrial shipyard cranes for sale: A shipyard crane is a gantry crane that can swing through the gantry frame of a rail vehicle or other ground vehicle. It is widely used in mechanical loading and unloading of ports and docks, construction and installation of ships in shipyards, and construction of large hydropower station dams. It is an indispensable and important equipment for mechanizing the production process.
2. Gantry crane: mainly used for outdoor yard, yard cargo, and bulk cargo loading and unloading operations.

2. Different structures
1. Made in china shipyard cranes equipment: It consists of structural part, mechanism part, electrical part and safety device part.
2. Gantry crane: Structurally, it consists of door frame, car traveling mechanism, lifting trolley and electrical parts.

3. Different characteristics
1. Shipyard crane: The effective space is small, which affects the use; the lifting wire rope is too long, which is not conducive to loading and unloading operations; in order to achieve horizontal amplitude, the wire rope needs to be compensated, which complicates the mechanism layout and increases the wear and tear of the wire rope.
2. Gantry crane: The performance and life of the sistema automatizado de grúas para astillero mechanism largely depend on lubrication; gantry cranes are widely used in port cargo yards due to their high utilization rate, wide operating range, strong adaptability, and strong versatility. application.
