Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a traveling mechanism for a tire crane. Background Art

[0002] There are many scenarios in life where gantry cranes are needed to complete material transfer operations, such as railway transfer stations, factories, etc.

[0003] However, for most cranes to be used, a cement foundation must be laid in advance at the site, two parallel crane tracks must be pre-buried, cables must be pre-buried, and cable trenches must be planned. This requires lengthy and costly initial site planning, and the crane's trolley's travel range is limited, making it inconvenient to transport the entire crane after use. Furthermore, traditional tire cranes often utilize sprocket and chain drive mechanisms, which are susceptible to wear and tear, and chains can easily become loose and stuck. When the chain becomes loose, the tensioning device must be replaced or adjusted promptly, resulting in complex maintenance, high costs, and a large space requirement. Therefore, we have proposed a traveling mechanism for tire cranes to address these issues. Utility Model Content
