A 3×4 m tempered glass panel 12 mm thick weighs 360 kg — impossible to handle manually without major risk of breakage and accidents. The vacuum cup robot allows millimetre-precise positioning of panels up to 1,400 kg. Complete guide: how it works, what equipment we use and why it is the only safe installation method.
Why large glass cannot be installed manually
A 3×4 m tempered glass panel at 12 mm thickness weighs 360 kg. Manual handling without specialised equipment risks breakage and serious accidents. The vacuum cup robot allows millimetre-precise positioning of panels up to 1,400 kg.
How the vacuum cup robot works
Vacuum cups create negative pressure on the glass surface. An industrial 200mm cup at 0.85 bar generates ~270 kg holding force. Multi-cup systems reach 1,400 kg total capacity.

Frequently Asked Questions
Why can't oversized glass be fitted by hand?
A toughened glass panel of 3,000 × 4,000 mm at 10 mm weighs 300 kg, and a 3×5 m insulated unit reaches 500+ kg. No team can physically handle these weights without a major risk of breakage, serious injury and the impossibility of precise positioning (2-3 mm errors destroy the seal).
How does the vacuum-suction glass robot work?
Vacuum suction cups create a negative-pressure zone (partial vacuum) on the glass surface. The adhesion force is proportional to the cup area and vacuum level, allowing safe and precise handling of panels weighing hundreds of kilograms, impossible to move by hand.
How much can an oversized glass panel weigh?
Toughened 10 mm glass weighs 25 kg/m², so a 3,000 × 4,000 mm panel reaches 300 kg (360 kg at 12 mm). A toughened 6+16+6 insulated unit at 3×5 m exceeds 500 kg — which is why fitting requires a vacuum-suction robot.
What precision is needed when fitting large glass?
Fitting large panels requires high precision — positioning errors of 2-3 mm destroy the perimeter seal. The vacuum-suction robot allows millimetre positioning impossible to achieve by hand, guaranteeing a correct and durable seal of the panel.
