Faster, safer, smarter
Demoulding precast concrete is quicker, cleaner and more efficient with vacuum handling technology. At Aerolift, we’ve revolutionised the process by replacing traditional lifting methods – such as hooks and embedded anchors – with state-of-the-art vacuum systems. Discover how our innovative ES series makes demoulding, lifting, and turning concrete elements easier than ever.
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. When 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.
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 – without damaging the mould or the product.
Thanks to the even surface pressure of the vacuum pad, the hardening time is significantly reduced to just 8–10 hours. And with the right equipment – like our ES series – it’s possible to demould, lift, rotate, and place concrete elements in a single operation.
Lifting with a concrete vacuum lifter has a number of great advantages, especially the ES series . Vacuum handling technology allows you to:
Concrete demoulding with vacuum handling ensures safety. The vacuum handling technology works on all airtight surfaces and the surface does not even have to be completely flat. If the power fails, a clear audio signal follows and you have several minutes before the vacuum reaches the lower limit. This time is more than enough to take corrective measures and to lower the concrete block to the ground.

Concrete demoulding by vacuum technology is a gain for production industries, but also for industries including internal transport, storage, transhipment and construction. Even heavy paper rolls and metal pipes can easily be lifted with vacuum handling.
The ES series includes advanced safety features. If a power failure occurs, an audible warning alerts the operator, and the system retains vacuum pressure for several minutes – providing ample time to safely lower the load.
The system works on airtight surfaces, even if they aren’t completely flat, ensuring broad application across different types of precast components.
Vacuum handling extends far beyond precast concrete. Aerolift vacuum systems are also used in the construction, storage, logistics, and metal industries – for lifting everything from paper rolls to steel pipes. The flexibility of the ES series makes it a valuable investment across sectors.
