Vacuum suction cups can be used to carry precast concrete components. By virtue of suction, they can be transferred from the production site to the transport vehicle or construction site. During the construction of concrete walls or floors, they can be used to fix construction tools or assist in positioning formwork. They can also be used to position detection equipment on the concrete surface to ensure the accuracy and stability of the detection. They can also be adsorbed on the concrete structure as a temporary fixing point for the aerial work platform to ensure the safety of construction workers.
