Description

Technical Field

[0001] The utility model relates to the technical field of container gantry cranes, in particular to a hoisting mechanism for container gantry cranes. Background Art

[0002] A container is a large cargo container with certain strength, rigidity and specifications for turnover. When using containers to transport goods, the goods can be loaded directly at the shipper's warehouse and unloaded at the consignee's warehouse. When changing vehicles or ships in the middle of the journey, there is no need to take the goods out of the container for reloading. It is very convenient to use. However, when lifting goods in warehouses or transfer stations, ordinary gantry cranes are used to lift containers. The structure is unstable and it is inconvenient to adjust according to the size of the container, so the use effect is not good.
