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

Understanding the classification of gantry cranes is more conducive to selecting and purchasing cranes.

Lifting machinery includes cranes, hoists, forklifts, elevators, and other equipment used for lifting and moving heavy loads.

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 automatických portálových jeřábů SEVENCRANE s pryžovou pneumatikou je technologie polohování kladkostrojů a kladkostrojů velmi důležitým obsahem. Za normálních okolností je provoz velkých a malých nákladních vozidel kontejnerových portálových jeřábů automaticky dokončován spoléháním na polohovací techniku. Ovladač potřebuje pouze ovládat zařízení. Situaci lze sledovat pomocí videa. Na rozdíl od konečné fáze zvedací operace, která vyžaduje lidský zásah, vyžaduje automatizace polohování velkých a malých vozidel vyšší technickou spolehlivost a přesnost.

With the continuous advancement of modern science and technology, the degree of automation in the lifting and transportation industry, known as the "machinery maniac", has increased significantly. Among many products, the double beam gantry crane has high site utilization, large operating range, and wide adaptability. The characteristics of wide range and strong versatility have ushered in strong market demand, making material loading and unloading operations in shipbuilding, freight, ports and other industries more convenient. As a long-established lifting and transportation machinery manufacturer, SEVENCRANE has been conducting technological innovation and continuously optimizing and upgrading its products based on user feedback to make its operation process more stable and its service life longer.
