Description

Technical Field

[0001] This utility model relates to the field of steel coil handling technology, specifically a steel coil lifting and handling vehicle. Background Technology

[0002] In the steel manufacturing and warehousing logistics sectors, steel coil handling trolleys are a common type of transportation equipment, primarily used for short-distance transfer, loading, unloading, and stacking of steel coils. Traditional steel coil handling trolleys typically consist of a frame, a traveling mechanism, a lifting device, and a limiting saddle. The limiting saddle's function is to secure the steel coil, preventing it from rolling or shifting during transport, thus ensuring stability and safety during handling.

[0003] Currently, most steel coil handling trolleys on the market adopt a fixed-spacing double-saddle structure, meaning the distance between the two limiting saddles is not adjustable. Because the diameter and weight of steel coils vary significantly depending on production needs, fixed-spacing saddles cannot accommodate coils of different specifications. This forces operators to use non-standard methods to secure the coils, such as using pads or binding straps. This not only increases operational complexity but also risks the coil slipping due to insecure securing, potentially leading to safety accidents.

[0004] To address the aforementioned issues, we have made improvements and proposed a steel coil lifting and transport vehicle. Utility Model Content
