TECHNICAL FIELD

[0001] The present application relates to the technical field of lifting devices, in particular to an intelligent self-balancing lifting device for lifting prefabricated T-beam templates. BACKGROUND

[0002] T-beams are a common structural form in bridge engineering, and the installation and lifting of their templates are important and indispensable steps in the construction process. Traditional T-beam template lifting often uses ordinary lifting devices or steel wires directly connected to the template legs, which has the problems of low lifting efficiency, poor balance, and easy damage to the templates.
