Handling glass panes in industrial manufacturing is demanding: glass is heavy, fragile, and cannot withstand harsh clamping grippers. Architectural glass can easily weigh 200 to 400 kg per pane, photovoltaic modules 18 to 35 kg, and laminated glass units can reach several tons in weight.manipulatorVacuum-assisted lifting devices are the standard for moving these loads without pendulum movement or damage.
Glass industry requirements for handling
Glass handling is characterized by a combination of critical factors:
High load capacity for large formats; architectural glass typically withstands 150 to 400 kg per pane.
Fracture sensitivity, no localized force peaks, no hard clamping.
Sensitive surfaces, coatings, mirror surfaces and anti-reflective coatings must not be damaged.
Large-format geometry, up to 6 meters in length for modern architectural glass.
High production volumes in PV module manufacturing with short cycle times.
Vacuum manipulators: pendulum-free and gentle
The vacuum traverse lifts the glass pane over a large area.suction platesUnlike a clamping gripper, the holding force is distributed across the entire suction surface, leaving no marks or edge damage. Multiple suction plates with individual pressure control can also accommodate irregular geometries.
Safety features are mandatory: Pressure sensors continuously monitor each suction plate; in the event of pressure loss, the movement stops immediately. Dual redundant vacuum circuits protect against component failure.
Handling glass panes with Zeilhofer manipulators
The articulated manipulator with vacuum traverse moves glass panes up to 800 kg without oscillation. For heavy laminated glass units or particularly large formats, theHub axle ZH90Up to 1,200 kg. The Acer rope manipulator complements the product range for the fast handling of lightweight PV modules with a large working radius.
The vacuum clamping process is individually tailored to the format, weight and surface, from architectural glass to PV modules to mirrors and coated special glass panes.
Typical applications in the glass industry
Architectural glass manufacturing: Pane handling before and after cutting, grinding and coating systems.
Insulating glass lines: Insert panes into the edge seal and form packs.
PV module assembly: Transferring modules between laminator, frame and junction box stations.
Mirror production and furniture glass: transporting sensitive surfaces gently.
Glass logistics and shipping: Place packages into transport racks without bouncing.
Ergonomics and cost-effectiveness
A broken stack of glass is expensive, and so is an injured employee. The vacuum manipulator solution protects both. At the same time, throughput increases: a single operator can handle even large formats safely and independently, without requiring a second person.
Individual design from a single source
Every glass production facility operates with its own formats and line cycles. Zeilhofer develops each solution individually: vacuum gripping, manipulator selection, and control systems all come from a single source in Holzkirchen. ISO 9001 certified, TISAX Level 2 with prototype protection.

Frequently Asked Questions (FAQ)
How heavy are glass panes in industrial manufacturing?
Depending on their size and thickness, industrial glass panes weigh between 20 and several hundred kilograms. Architectural glass regularly reaches 150 to 400 kg per pane, photovoltaic modules 18 to 35 kg, and laminated glass units correspondingly more.
Which lifting aids are suitable for handling glass panes?
Manipulators with vacuum traverses are standard in the glass industry. The vacuum clamp distributes the holding force over a large area and gently, and the manipulator guides the pane without any pendulum motion. For heavy composite modules up to 1,200 kg, theLifting axleZH90.
What requirements does the glass industry place on the recording?
Suction plates with soft pads prevent indentations, and pressure control continuously monitors the suction force. In case of breakage or pressure loss, the movement stops immediately. For PV modules, electrically conductive material is also important.
Does Zeilhofer offer customized solutions for the glass industry?
Yes. Grippers, suction plates andDevicesare individually designed to suit the format, weight and surface of the glass components, from architectural glass to PV modules to laminated glass packages.
