Faster, safer, smarter<\/strong>
\nDemoulding precast concrete is quicker, cleaner and more efficient with vacuum handling technology<\/a>. At Aerolift, we\u2019ve revolutionised the process by replacing traditional lifting methods \u2013 such as hooks and embedded anchors \u2013 with state-of-the-art vacuum systems. Discover how our innovative ES series makes demoulding, lifting, and turning concrete elements easier than ever.<\/p>\n

How classic demoulding of concrete works<\/h2>\n

Concrete objects are poured in a mould that has to be removed when the concrete has hardened. During the hardening time embeds are placed into the concrete. The required hardening time before demoulding by the aid of embeds is approximately 24 hourds, depending on the circumstances.\u00a0When the concrete is hardened the mould has to be removed before demoulding and lifting. Usually the mould is disassembled, or even destroyed. Lifting is done by connecting a chain with hooks to the embeds which where mounted into the concrete before it hardened. The embeds are used for lifting and if required turning the products. After construction the embeds often have to be removed manually.<\/p>\n

How does demoulding through vacuum technology work<\/h2>\n

With vacuum handling, no embeds or inserts are needed. Instead, a suction pad is applied directly to the concrete surface. Once the air is extracted, a powerful vacuum grip forms, enabling safe and seamless lifting \u2013 without damaging the mould or the product.
\nThanks to the even surface pressure of the vacuum pad, the hardening time is significantly reduced to just 8\u201310 hours. And with the right equipment \u2013 like our ES series<\/a> \u2013 it\u2019s possible to demould, lift, rotate, and place concrete elements in a single operation.<\/p>\n
