Description

Technical Field

[0001] The utility model relates to the technical field of automatic lifting devices, in particular to an automatic material lifting device for a crane. Background Art

[0002] An automatic lifting device is an automated mechanical device used to lift materials vertically. It improves the efficiency and safety of material handling and is widely used in industrial production, logistics and warehousing, construction, and other fields. An automatic lifting device typically includes key components such as a drive system, a load platform, a control system, and safety devices.

[0003] In order to improve the efficiency of the entire operation process, existing cranes generally need to use automatic material lifting devices to realize the up and down transportation of materials, adopt traction mechanisms to realize the vertical lifting of materials, and use traction ropes to drive the hooks to rise and fall, thereby lifting the materials. A driving device is installed on the surface of the traction mechanism to drive the traction mechanism to move along the surface of the track.

[0004] However, since the material is lifted by the traction rope, the crane may shake during the lifting, which will cause the material to shake through the traction rope, resulting in an inability to lift the material stably. At the same time, since the material needs to be moved to the specified position by the traction rope, the traction rope will inevitably swing during the movement, resulting in an inability to accurately move the material to the specified position.
