Description

Technical Field

[0001] The utility model relates to a lifting device, in particular to a tire-type track-laying crane. Background Art

[0002] A tire crane generally refers to a crane that travels on a tire chassis. Tire cranes are widely used, and one of the application scenarios is the laying process of various railway tracks and tunnel tracks. For example, Chinese patent CN222204611U discloses a tire-type track-laying crane, which sets a limiting component, starts the winding motor with the wire rope to wind up, moves the hook upward, and gradually enters the interior of the limiting cylinder until the hook completely enters the limiting cylinder. The limit seat blocks the hook from continuing to move upward, and the winding motor stops working, limiting the hook inside the limiting cylinder, limiting the position of the hook that is not used for lifting materials related to track laying, and effectively preventing the hook from accidentally hitting foreign objects due to shaking. However, most tracks currently use I-beam structures, and this crane is not convenient to cooperate with conveying equipment to drag the track.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content
