Description

Technical Field

[0001] The utility model relates to a mobile hoisting observation tower, belonging to the field of construction. Background Art

[0002] In recent years, with the rise of subways and the development and utilization of urban underground space, in the risk control of deep foundation pit construction in construction projects, especially in terms of personnel safety operations and during foundation pit excavation, due to the limitations of on-site conditions, construction management personnel often cannot fully grasp the construction dynamics and progress of workers. At present, in the risk control of deep foundation pit construction, management personnel often go down to the foundation pit to monitor the construction dynamics and progress in real time, or personnel stand at the edge of the foundation pit to observe the situation inside the foundation pit. When this type of personnel monitoring method is used, the viewing area is often one-sided and incomplete. Therefore, this application proposes a mobile hoisting observation tower.
