Las grúas pórtico montadas sobre rieles, también conocidas como grúas rmg, son una parte importante de las estaciones ferroviarias de contenedores en todo el mundo. Estas potentes y eficientes máquinas desempeñan un papel vital en el buen funcionamiento de estas estaciones y ayudan a mover y apilar contenedores con facilidad.

Rail mounted gantry cranes are composed of main beams, rigid and flexible gantry legs, running trolleys, lifting mechanisms, trolley running mechanisms, electrical systems, operating cabs, etc. According to the yard operation process, the cantilever in the direction of the single gantry leg or the double gantry leg becomes a single cantilever or double cantilever model, and the non-cantilever model becomes a cantilever-free model.

Rail mounted gantry crane is a rail-operated lifting equipment. It is composed of beam, support legs, crane travelling mechanism, trolley, electric equipment and so on, with the electric hoist as hoisting mechanism. The whole machine has the characteristics of simple structure, convenient installation and maintenance, low cost and strong performance.

Una grúa pórtico montada sobre rieles (RMG) es un tipo de grúa pórtico. Su estructura metálica es similar a un pórtico, con dos patas instaladas debajo de la viga principal, lo que le permite caminar directamente sobre la vía en el suelo. Puede haber vigas voladizas sobresalientes en ambos extremos de la viga principal. Las grúas pórtico sobre raíles (RMG) se fabrican según las necesidades individuales del cliente y están disponibles en diferentes alturas y luces de apilamiento.

Rail mounted gantry crane is a type of lifting equipment that is installed horizontally in workshops, warehouses and yards for material lifting. Because its two ends are located on tall concrete columns or metal supports, the bridge of the gantry crane runs longitudinally along the tracks laid on both sides of the elevated frame.

 Rail mounted gantry cranes,also known as RMG cranes,are essential pieces of equipment used in various industries for efficient material handling. These cranes are commonly found in ports, intermodal terminals, and manufacturing facilities.
