Gantry crane is a bridge-type crane whose bridge is supported on the ground track through outriggers on both sides.

Our products are exported to more than 80 countries around the world. It is worth mentioning that our customers have all given good feedback after using our cranes.

There are many structural types of gantry cranes. The performance of gantry cranes produced by different gantry crane manufacturers are also different.

The SEVENCRANE rubber tyre gantry crane is the main equipment of the container terminal bridge. Currently, industrial rubber tyre gantry crane trolleys generally use rimless wheels and are designed with a guide device (horizontal wheel) added to one side of the track. This structural form reduces the manufacturing deviation and the impact of track gauge changes on the trolley operation under trolley load conditions. Rolling friction replaces sliding friction between the horizontal wheel and the side of the track, and the frictional resistance endured by the operating mechanism is greatly reduced. However, in the actual operation process, the phenomenon of the trolley deviating from the track often occurs. That is, when the trolley is running back and forth, the center of the wheel seriously deviates from the center of the track, causing the horizontal wheel to squeeze the side of the track, increasing the friction between the two. This causes abnormal wear of the horizontal wheels and tracks, especially when the trolley travels at a full speed of 70 m/min, posing a major safety hazard to the trolley's operation.

Nos pórticos automatizados com pneus de borracha SEVENCRANE, a tecnologia de posicionamento de guinchos e carrinhos de içamento é um conteúdo muito importante. Em circunstâncias normais, a operação de caminhões grandes e pequenos de guindastes de pórtico para contêineres é concluída automaticamente com base na tecnologia de posicionamento. O controlador só precisa operar o equipamento. A situação pode ser monitorada por vídeo. Diferentemente da etapa final da operação de içamento, que requer intervenção humana, a automação do posicionamento de veículos de grande e pequeno porte exige maior confiabilidade e precisão técnica.
