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.

U SEVENCRANE automatiziranim portalnim dizalicama s gumenim gumama, tehnologija pozicioniranja dizalice i kolica za dizalicu vrlo je važan sadržaj. Pod normalnim okolnostima, rad velikih i malih kamiona kontejnerskih portalnih dizalica automatski se dovršava oslanjanjem na tehnologiju pozicioniranja. Upravljač treba samo upravljati opremom. Situacija se može pratiti putem videa. Za razliku od završne faze operacije podizanja koja zahtijeva ljudsku intervenciju, automatizacija pozicioniranja velikih i malih vozila zahtijeva veću tehničku pouzdanost i točnost.
