Glass panels are handled in many workshops: tempered glass, insulated glass units, aluminum doors and windows, facades, refrigerators and display cabinets. A 10 mm panel measuring 2 x 3 m already weighs about 150 kg, and large insulated or laminated units are much heavier. Glass is thin for its area, so it flexes easily, its edges are sharp and its smooth surface is hard to grip.
Carrying by hand or with handheld suction cups usually takes 4 to 6 workers for a large panel. One person out of step is enough for the panel to tilt, hit an edge and break, causing cuts, back injuries and scrapped goods. Flipping is even harder: standing a panel up from the cutting table onto an A-frame rack (90 degrees), or turning it over 180 degrees to process or inspect the back side.
Glass is flat and airtight, which makes it ideal for vacuum lifting. A vacuum lifting pad consists of a frame, 4 to 8 rubber suction cups, a vacuum source, a gauge and a check valve that holds the vacuum. The vacuum source can be compressed air, mains power or battery, chosen by panel weight and workplace.
The hardest part of glass handling is turning the panel without any impact. Depending on the process, FullSharp usually applies one of these methods:
General rule: always lock the tilt angle before traveling, and only flip after the panel is lifted clear of the table.
| Equipment | When to use | Typical load |
|---|---|---|
| Jib crane with hoist | Serves a circular area around a cutting table or edger | A few hundred kg up to about 1 ton |
| Lift-assist manipulator | Frequent flipping, precise positioning, repetitive work | Tens to a few hundred kg |
| Overhead rail system with hoist | Moves panels along a line, covers a rectangular area | Depends on rail type, usually 200 to 500 kg |
| Battery vacuum lifter on an existing crane | Glass stores, loading and on-site installation | Depends on pad configuration |
For light to medium panels that are flipped often, see the 100 kg vacuum gripper for glass panes on a light crane.
A multi-cup vacuum lifting pad on a jib crane, rail system or manipulator. For very heavy panels or work in warehouses and on site, choose a battery-powered vacuum lifter.
Soft rubber cups press evenly on the glass and do not scratch it when glass and cups are clean. Large panels need enough evenly spaced cups to avoid flexing.
Use a pad frame with a pivot and locks at 0, 90 and 180 degrees, or a manipulator with a tilting head. Lift the panel clear of the table first and lock the angle before moving.
A proper system has a check valve or vacuum reservoir that holds the load for a period, plus a low-vacuum alarm so the operator can lower the panel safely.
Length (m) x width (m) x thickness (mm) x 2.5 = kg. A 2 x 3 m panel 10 mm thick weighs about 150 kg.
