Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically to a concrete material lifting device for construction. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. It is one of the most important civil engineering materials in modern times. The term concrete usually refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water in a certain proportion.

[0003] During the construction process, concrete materials often need to be transported to a certain height for workers. For high-altitude construction, cranes or other hoists can be used for lifting and transporting. However, for low-altitude construction, setting up cranes and other equipment would increase construction costs. Since concrete materials are mostly heavy, they cannot be transported upwards by manpower. Therefore, there is a need to provide a concrete material lifting device suitable for low-altitude construction. Summary of the Invention
