Description

Technical Field

[0001] The utility model relates to the technical field related to construction engineering, in particular to a gantry for construction engineering. Background Art

[0002] The gantry is a kind of lifting equipment developed according to the daily production needs of small and medium-sized factories for handling equipment, warehouse loading and unloading, lifting and repairing heavy equipment and material transportation. It is suitable for places such as mold manufacturing, auto repair factories, mines, and civil construction sites. It is commonly used for material transportation and the up and down use of construction personnel in construction, realizing the mechanization of lifting, which has the advantages of reducing manpower, reducing production and operation costs, and improving work efficiency. During lifting, the building materials are suspended by a hook and then lifted by an external power structure. However, the overall structure of the existing hook is relatively fixed. During use, the overall movement range of the hook is limited, which leads to a limited overall lifting range of the hook. As a result, when lifting large building materials, the stability of the lifting process may not be guaranteed, causing the building materials to shake.

[0003] Therefore, we propose a construction engineering gantry to solve the above problems. Utility Model Content
