(1) According to the main girder classification, general gantry cranes can be divided into single main girder gantry cranes and double main girder gantry cranes. (2) According to cantilever classification, general-purpose gantry cranes can be divided into single-cantilever gantry cranes, double-cantilever gantry cranes and non-cantilever gantry cranes.

Shipbuilding gantry cranes are common hull lifting and assembly equipment in shipbuilding ports and terminals. With the rapid development of transport ships and their increasingly large size, shipbuilding gantry cranes are developing in the direction of large size, high speed and heavy load.

The gantry crane is a bridge-type crane in which the horizontal bridge is set on two legs to form a gantry shape. This kind of crane runs on ground tracks and is mainly used for handling and installation operations in open storage yards, shipyards, power stations, ports, railway cargo stations, etc.

At present, the lifting height of conventionally produced outdoor gantry cranes is generally 12-20 meters. In actual use, users often put forward higher lifting height requirements. There are several common solutions to solve the problem of large lifting height of outdoor gantry cranes.

Rubber tire gantry crane is a common lifting equipment and a thriving equipment in industrial production. It adopts a rubber tire structure, so it has good mobility and flexibility, can be operated on various complex sites, and is very convenient to install and disassemble. Therefore, rubber tire gantry cranes are widely used in many fields, such as construction sites, docks, ports, logistics parks, photovoltaic power generation and other fields.

En comparación con las grúas generales, las grúas inteligentes tienen inteligencia artificial, que reemplaza o ayuda al trabajo mental humano reemplazando el trabajo físico humano. Al integrar sensores con software inteligente de toma de decisiones y grúas, se logra percepción, análisis, razonamiento, toma de decisiones y control Función, logrando la interacción e integración entre humanos y objetos, reemplazando la percepción, toma de decisiones y ejecución manual, permitiendo la grúa para adaptarse a los cambios en el entorno laboral. Su flujo de trabajo es el mismo que el de una grúa general, pero el control inteligente agregado puede reemplazar la visión, el oído y el olfato humanos. Los órganos sensoriales como los sentidos y las extremidades reemplazan el juicio del operador para realizar las acciones correspondientes, completando el reconocimiento, la percepción, la operación, y gestión durante la operación de la grúa.
