AI Technical Summary
Existing hoisting equipment cannot adapt to precast cap beams of different sizes, resulting in low construction efficiency and difficulty in meeting the needs of diverse construction scenarios.
A hoisting unit is designed, comprising two hoisting units spaced apart and symmetrically arranged along a first direction. Each unit includes a crossbeam, a first clamping mechanism, and a second clamping mechanism. Width adaptation is achieved through a first drive assembly and a connector, and length adaptation is achieved through a second drive assembly and a clamping block. Stable clamping is ensured by a pressing assembly.
It achieves stable clamping of precast cap beams of different sizes, improves construction efficiency, avoids frequent disassembly and adjustment of hoisting equipment, and adapts to the needs of diverse construction scenarios.
