Technical Field

[0001] The utility model relates to the technical field of truss structures, in particular to an electric lifting structure group for a truss. Background Art

[0002] A truss is a structural form that consists of a triangular or polygonal grid structure composed of interconnected rods. It is usually used to support and reinforce engineering structures such as buildings, bridges, and towers. Truss rods can be made of steel, aluminum alloy, wood and other materials, and are characterized by light weight, high strength and good rigidity. Truss structures can effectively bear loads and have a large open space, so they are widely used in large-span structures, stadiums, exhibition halls, stages and other places. The design of truss structures needs to consider factors such as the connection method of rods, node design and overall stability.

[0003] In the prior art, the manual lifting truss is a simple and practical stage construction equipment. Although it has many conveniences, it also has some disadvantages, mainly including the following points: strong dependence on manpower, low lifting efficiency, operational safety issues, difficulty in precise control, high intensity of physical labor, etc. Based on these problems, we proposed an electric lifting structure group for trusses.
