But how do a vacuum lifter work in practice? These machines create a vacuum seal between the lifting device and the object, allowing operators to handle large, flat, and heavy materials safely, efficiently, and ergonomically.
Vacuum lifters are commonly used in manufacturing, construction, logistics, and warehousing industries. They’re ideal for lifting non-porous or semi-porous materials such as glass, stone, metal sheets, wood panels, concrete blocks, and even food-grade products.
Vacuum lifters function by creating a negative pressure (vacuum) between a suction pad and the surface of an object. This pressure differential allows the suction pad to cling tightly to the object, enabling it to be lifted, transported, and precisely positioned.
Vacuum Pump: The vacuum pump is the heart of the system. It generates the vacuum needed to grip the object securely.
Suction Pads (End Effectors): These are in direct contact with the material being lifted. They must be the correct size and shape to form an airtight seal.
Control System: Allows the operator to manage suction, tilting, lifting, and releasing the load.
Lifting Mechanism: Often paired with cranes or forklifts, it performs the vertical or angular lifting motion.
The operator aligns the vacuum lifter above the object. The suction pad should cover enough surface area to create a reliable seal.
The pump is activated, drawing air out from between the pad and the surface, thus creating a vacuum. This causes atmospheric pressure to push the object against the pad, securing it tightly.
Once a firm seal is formed, the crane or hoist lifts the object vertically or tilts it for placement. Many models also offer 90° to 180° tilting and 360° rotation.
To release, the system allows air back into the suction pad, neutralizing the vacuum and detaching the object smoothly.
These models are powered by electric pumps and often used for precise and repetitive tasks. Ideal for indoor applications with consistent power supply needs.
Cordless and mobile, battery-operated lifters like the AVLP series by Aardwolf offer convenience, especially in construction or remote job sitesGeneral-Catalog-2025.
Often used in stone and glass industries, these systems are powered by compressed air and are preferred in environments where electricity is limited or hazardous.
Self-cycling systems powered by mechanical pumps, often with hand or foot controls. Ideal for lightweight applications or environments without electricity or compressed air.
Audio-Visual Alarms: Alert operators to low vacuum levels.
Vacuum Reservoir Tanks: Provide backup suction in case of pump failure.
Slide Valve Mechanisms: Simple controls for engaging and disengaging suction.
