Is a roll-out cantilever rack only for laser cutting? No. It suits plasma tables, automatic saws, press brakes with long tooling, and any cell fed with bundle stock. Laser shops adopt it first because their cycle times make waiting expensive.
How fast is a pick, realistically? A trained operator extends the tier, slings the bundle and lands it on the table in well under a minute for a normal bundle. The thirty-second figure applies to the tier access itself, not the full lift.
Can it replace a forklift? For storage and machine feeding, largely yes, provided the crane covers the cell and the hook height clears the top tier. Forklifts still move pallets of finished parts.
Does it work in an existing building with a low roof? Tier count is set by hook height, so a low building gets fewer tiers over a longer run. Herochu lays that out from a roof and crane survey before quoting.
How long can an electric telescopic tier extend? Stroke is set by the bundle depth and the crane’s approach. Most installations extend far enough for a vertical lift with the spreader clear of the tier above.
What happens during a power failure? The mechanical lock holds the tier in place and the brake holds the carriage. Recovery is manual and documented in the operating instructions.
Can it be retrofitted to an existing cantilever rack? Sometimes, if the frame and columns were built with that provision. A static rack welded without carriage guides generally cannot be converted safely, and Herochu checks the frame drawings before agreeing to a retrofit.
What maintenance does it need? Roller and guide inspection, brake check, limit switch verification and a load test at defined intervals. Bearings and drives are standard industrial components, not proprietary parts.
