Abstract
Description
Technical Field
[0001] This utility model relates to the field of precast T-beam formwork hoisting, specifically to a safe horizontal moving hoisting device for precast T-beam formwork. Background Technology
[0002] In bridge construction, the installation and dismantling of precast T-beam formwork is a crucial step, and the safety and efficiency of its hoisting and transportation directly affect the project progress and construction quality. Traditional methods for hoisting precast T-beam formwork often employ simple lifting tools or directly use gantry crane hooks. These methods have many drawbacks. Firstly, simple lifting tools have poor structural stability, making it difficult to ensure even stress distribution during the hoisting of large precast components, leading to swaying, tilting, or even falling, posing serious safety hazards. Secondly, directly using gantry crane hooks makes it impossible to flexibly adjust the lifting points according to the weight and structural characteristics of different formwork. For T-beam formwork with lighter weight and varying flange lengths, not only is installation accuracy difficult to guarantee, but extensive manual adjustments are required during installation and dismantling, resulting in low construction efficiency and increased labor costs. Furthermore, traditional hoisting methods are prone to damage to the formwork due to improper hoisting, transportation, and placement, causing economic losses. Therefore, there is an urgent need for a safe and efficient horizontal lifting tool that can adapt to different specifications of precast T-beam formwork to solve the problems existing in current technologies.
