AI Technical Summary
Existing lifting equipment requires manual fixing and unhooking when hoisting ultra-high I-beams, which is inconvenient, inefficient, and poses risks associated with working at heights.
A self-locking and self-unhooking lifting device for ultra-high-altitude beams was designed, comprising a lifting plate, pulley assembly, jacking assembly, locking mechanism, and reset mechanism. Through automated operation, the lifting plate achieves self-locking and self-unhooking, thereby improving lifting efficiency.
It achieves automated fixing and unhooking of lifting pallets, improving lifting efficiency, reducing the risks of high-altitude operations, and meeting usage requirements.
