AI Technical Summary
Technical Problem
Traditional steel truss lifting devices have poor stability in umbrella-shaped steel trusses, and four electric hoists are insufficient to support the lifting of large-area and heavy steel trusses.
Method used
The system employs fourteen sets of installation components and fourteen electric hoists arranged in a circular array. The steel truss is fixed at fourteen points, and the hoists are used for lifting via chains and hooks, with power provided by a motor drive unit.
Benefits of technology
It achieves stability and sufficient power for steel truss lifting, and can meet the lifting needs of larger and heavier umbrella-shaped steel trusses.

Abstract
The utility model relates to the technical field of steel trusses, in particular to a modularized umbrella rib type steel truss support-free lifting device which comprises a bin body and fourteen sets of installation assemblies arranged at the top end of the bin body, and the fourteen sets of installation assemblies are in an annular array shape. The installation assemblies are arranged on the inner side of the top of the bin body, the electric hoisting hoists are arranged on the outer sides of the installation assemblies, the number of the electric hoisting hoists is fourteen, and the electric hoisting hoists are installed on the outer sides of the fourteen installation assemblies respectively. The fourteen electric hoisting hoists can be installed through the fourteen installation assemblies, and the fourteen electric hoisting hoists are arranged on the inner side of the top of the bin body in an annular array shape; the fourteen electric hoisting hoists symmetrically and uniformly hook a steel truss girder through fourteen lifting hooks, so that fourteen point positions on the steel truss can be fixed, the movement of the steel truss is more stable through simultaneous traction and lifting of the fourteen point positions, meanwhile, the fourteen electric hoisting hoists are used at the same time, the power is very sufficient, and the hoisting efficiency is greatly improved. And the device can adapt to large and heavy umbrella rib type steel trusses.
