Vacuum lifters: technology, use and selection at a glance

Anyone who has to move heavy glass panes, stone slabs or metal panels without damage quickly reaches the limits of chains, slings and hooks. Vacuum lifters solve this problem - they grip the load over a large area without damaging the edges and distribute the force evenly across the whole surface. This guide explains how they work, which designs exist and what to look for when choosing one.

A vacuum lifter is a lifting device that grips loads by means of negative pressure. Air is extracted at the contact surface between the suction pad and the workpiece. The resulting pressure difference creates the holding force. The larger the suction area and the higher the vacuum, the heavier the load that can be handled.

The basic principle is simple - the technical implementation is not. Industrial vacuum lifters for loads from 200 kg work with several suction circuits, integrated vacuum pumps, pressure monitors and safety valves. A pressure drop in the system automatically triggers an alarm and prevents the load from being set down in an uncontrolled way.

Distinction from the glass lifter: the term 'glass lifter' describes the same type of device but refers to its classic use in glazing. Vacuum lifter is the technically correct generic term and covers all materials - glass, stone, metal, concrete.

Hand-guided vacuum lifters

For loads up to approx. 400 kg. Two to four operators guide the device by hand. Used mainly for laying natural stone, large-format tiles or small-format glass panes close to the ground. No crane coupling required.

Crane-coupled vacuum lifters (glass lifting systems)

The main category for facade and building construction. The device is attached to the load hook of a mini crane, roto telehandler or mobile crane. Typical load capacities are between 500 kg and 3,000 kg. Modern systems allow continuous rotation and tilting of the load - important for positioning facade elements with millimetre precision.

Special features of crane-coupled systems:

• Multi-circuit vacuum system: if one suction circuit fails, the others hold the load

• Integrated battery reserve: maintains the vacuum even when the pump stops

• Radio remote control: the operator can guide the load from an optimal position without direct contact

• Tilt and rotation function: the pane is aligned directly at the installation point

Vacuum lifters for telehandlers

Roto telehandlers (e.g. the Manitou MRT series) can be combined with vacuum lifters via the quick-change system. The telehandler provides lift and reach, the vacuum lifter a secure grip. On sites without space to set up a crane, this combination is the most economical solution.

The relevant parameters when selecting:

• Rated load capacity: maximum load in kg - always choose with a safety factor of at least 2:1 relative to the actual load

• Suction area: determines the achievable holding force; larger panes require more suction heads

• Vacuum level: stated in mbar; the deeper the vacuum, the higher the holding force per square centimetre

• Number of suction circuits: at least two for safety-relevant applications (in line with applicable Belgian safety rules and NBN EN standards)

• Rotation range: 0-360 degrees on modern systems

• Tilt angle: +/-90 degrees allows horizontal and vertical lifting

• Power supply: 230 V mains, 24 V battery or pneumatic

• Dead weight: relevant for the remaining payload of the crane

Glazing and facade installation

The classic field of application. Triple glazing for office buildings weighs 380-600 kg depending on the format, and special panes for lobbies and showrooms regularly exceed 800 kg. These loads cannot be positioned without damage using muscle power, lifting slings or simple crane hooks. A crane-coupled vacuum lifter grips the pane flat, and the operator rotates it into the installation position by radio control.

Natural stone and large-format tiles

Stone slabs from 600 x 600 mm with a thickness of 30 mm can weigh more than 50 kg each in granite. Conventional laying is physically demanding and prone to errors. Vacuum lifters allow precise placement without crushed fingers or scratches on the polished surface.

Machine relocation and industrial installation

Smooth machine parts, steel plates or stainless steel covers can be moved faster and with fewer staff using a vacuum lifter than with conventional lifting gear. Prerequisite: the surface must be airtight enough to build up sufficient vacuum.

Solar panel installation

Solar modules are fragile, light and offer no mechanical gripping points. Vacuum lifters are the standard tool for installing large photovoltaic systems.

Step 1 - Determine load and geometry
Define the weight and dimensions of the heaviest planned load. Weight x 2 = minimum rated load capacity of the vacuum lifter.

Step 2 - Check surface condition
Vacuum lifters only work on airtight, smooth surfaces. Rough concrete, heavily textured glass or porous natural stone can prevent the required vacuum level. Manufacturer data sheets list the suitable materials.

Step 3 - Match the lifting equipment
The vacuum lifter is always an attachment. The carrying system - mini crane, roto telehandler or mobile crane - must be able to carry the sum of the load and the dead weight of the lifter. With a roto telehandler, the reduced load chart with attachment must be taken into account.

Step 4 - Clarify safety requirements
For loads above people or in public areas, the requirements of applicable Belgian safety rules and NBN EN standards apply. At least two independent vacuum circuits and a holding time test before each use are recommended.

Step 5 - Decide between renting and buying
If you only need vacuum lifters for individual projects, renting is more economical. Purchase costs for crane-coupled systems range from 15,000 to 60,000 euros depending on equipment. For a site run in-house, renting pays off from day one.

The relevant basis for vacuum lifters in professional use is the Code on Well-being at Work, Book IV (work equipment), supplemented by the applicable NBN EN standards. Key requirements:

• Before each use: holding time test with the planned load; the vacuum may only drop minimally within a defined time

• At least two independent suction circuits for loads above people

• Periodic inspection by an external technical inspection body (EDTC/SECT)

• Work instructions and operator briefing before work begins

• PPE for everyone in the load area

Luibl Rental supplies rented systems with current inspection certificates and, on request, advises on the necessary safety measures on site.

Renting makes sense if:

• vacuum lifters are only needed for one or a few projects

• different loads and glass formats require different suction heads

• you do not have your own crane - Luibl rents out mini crane and vacuum lifter as a combined solution

• investment capital is to be preserved

Buying pays off with:

• permanent utilisation with similar loads

• your own crane fleet and a fixed usage profile

• special requirements that no standard rental unit meets

Which surfaces are suitable for vacuum lifters?
Smooth, non-porous and airtight surfaces: float glass, polished natural stone, painted metal, stainless steel, ceramics. Not suitable: rough concrete, textured glass, open-pored sandstone.

Can I use a vacuum lifter without a crane?
Yes - for loads up to approx. 400 kg there are hand-guided systems operated by two to four people without lifting gear. For heavier loads, a crane or telehandler is required as the carrier.

How long does the vacuum hold if the pump fails?
Modern systems have an integrated battery reserve. Depending on the system, the holding time without an active pump is 30-60 minutes - enough to set the load down in a controlled way.

What does it cost to rent a vacuum lifter?
Rental costs depend on load capacity, equipment and rental period. At Luibl you can receive a combined offer of vacuum lifter and suitable crane or roto telehandler on request.

Do I need a special permit to use one?
No - but a risk analysis and work instructions under the Code on Well-being at Work, Book IV (work equipment) are required for professional use. Luibl will be happy to advise you on this.

The vacuum lifter expertise within the Luibl Group comes from Uplifter - a specialist with more than 20 years of experience in glass lifting technology that has been part of the Luibl Group since early 2026. Uplifter develops and produces the UPG series in-house and also rents it out.

The UPG models are silicone-free glass lifters with a dual-circuit vacuum system, mains-independent battery power (up to 8 hours of operation) and an acoustic vacuum loss warning. All models are designed for crane use and can be combined directly with Maeda mini cranes.
