Operators should carry out inspections and maintenance work for each shift according to daily maintenance requirements, fill in operation records, shift handover records, and do a good job in shift handover work.

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

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.
