Description

Technical Field

[0001] The utility model belongs to the technical field of lifting vehicles, in particular to a light movable remote-controlled lifting operation platform. Background Art

[0002] In the industrial and construction fields, climbing operations are extremely frequent. Currently, climbing operations are mostly carried out by setting up scaffolding or using aerial platforms. Setting up scaffolding is labor-intensive and involves great safety risks. A aerial platform is large in size, inconvenient to move, and has a high purchase cost. In addition, the scissor-type brackets used in existing aerial platforms will move to one side of the platform after being raised, which will cause the center of gravity of the platform and the center of gravity of the scissors to be on different vertical lines, causing the aerial platform to overturn. At the same time, some existing aerial platforms use a lifting fence. Although this is convenient for construction workers to operate, if the fence is not raised when rising to a high altitude, a safety accident is very likely to occur.

[0003] Therefore, we need to design a lightweight, movable remote-controlled lifting operation platform to solve these problems. Utility Model Content
