Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a mobile concrete lifting device. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities. Construction projects are the planning, investigation, design, construction, completion, and other technical work and completed engineering entities for the construction, reconstruction, or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines, and equipment.

[0003] Concrete is a general term for composite materials made of gel material, aggregate and water in appropriate proportions and hardened after a certain period of time. During the construction process, some concrete needs to be transported to a certain height. Currently, large concrete hoists are mostly used to lift concrete. However, for small-scale lifting, using large concrete hoists is a waste of resources and inconvenient to operate, which reduces the work efficiency of workers. Therefore, we propose a mobile concrete lifting device to solve the above problems. Utility Model Content
