In most laser cutting shops two or three people carry each steel sheet from the bundle to the machine bed, then carry the cut sheet away. Large sheets are heavy and sharp, and one slip scratches the surface or cuts a hand. The customer in this project wanted one person to do the job, but the floor around the machine was already full and there was no room for a crane base.
FullSharp bolted a 500 kg jib crane straight onto a steel column of the building next to the cutter, fitted an electric chain hoist with wireless remote and hung the FS-WDL1000-2S two pad mechanical vacuum lifter. The lifter needs no electricity and no compressed air: gripping and releasing are controlled entirely by the chain going tight or slack.

Instead of a separate post, we clamped steel mounting plates to the building H-column with bolts and fitted the slewing pivot and arm to them. The arm swings around the column, covering the cutter bed and the sheet bundle, while the floor below stays clear for forklifts.
An electric chain hoist runs on the arm. The operator holds the wireless remote to lift and lower with one hand and guides the sheet with the other. The hoist cable hangs from hooks along the arm, so nothing snags while slewing.
The lifter has two Ø450 pads at the ends of a beam frame, with the vacuum valve body in the middle hanging from the hoist hook. Lower it until both pads sit on the sheet and raise the hoist: a tight chain makes the valve create the vacuum, the pads grip and the sheet comes up. No buttons, no cables, no air hoses.
To release, set the sheet down and keep lowering until the chain is fully slack; only then does the valve vent. While the sheet is in the air it cannot be dropped by a wrong action, and a power cut does not affect it. A gauge on the body shows the vacuum before lifting.
The hoist carries the sheet; the operator only guides it and presses the remote.
No buttons on the lifter; it releases only after the sheet is set down and the chain is slack.
The crane hangs on an existing column; forklifts and people pass underneath.
Steel H-columns or stiff box columns are suitable. FullSharp first surveys the column size, height and required reach, then checks the load on the column. Concrete columns need a different mounting or a separate post.
Yes. The vacuum is created when the chain is tight and is kept while the sheet hangs. It releases only after the sheet is set down and the chain is fully slack, so a hoist power cut does not drop it. The sheet surface should be flat with no holes right under the pads.
The FS-WDL1000-2S frame is about 1.5 m long, which suits common laser cutter sheet sizes. For longer or thin, flexible sheets a 4 or 6 pad model is better. Send us sheet size, thickness and the heaviest sheet weight and we will choose the right model.
