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.

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

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.

In SEVENCRANE automated rubber tyred gantry cranes, the positioning technology of hoist and hoist trolleys is a very important content. Under normal circumstances, the operation of large and small trucks of container gantry cranes is automatically completed by relying on positioning technology. The controller only needs to operate the equipment. The situation can be monitored by video. Unlike the final stage of the lifting operation, which requires human intervention, the automation of large and small vehicle positioning requires higher technical reliability and accuracy.
