Description

Technical Field

[0001] The utility model relates to the technical field of steel material transportation, in particular to a steel structure transportation device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] At present, steel structures on construction sites are generally transported by lifting during transportation. However, some construction sites cannot be entered by large equipment due to road restrictions, such as mountainous areas and rural areas. In this case, manual transportation is required. The current manual transportation method mainly uses a trolley, that is, the steel structure is placed on a trolley and pulled manually. However, since some steel structures are relatively long, they are prone to imbalance during transportation, which can cause them to fall, making transportation inconvenient and easily injuring workers.

[0004] Therefore, in response to the above problems, we propose a steel structure handling device. Utility Model Content
