WM CraneVac 3000 Battery-Powered Crane Vacuum Lifter

A self-contained battery-powered crane vacuum lifter for handling full sheets and heavy panel stock without a forklift and without a second pair of hands. It hangs from an existing gantry, jib or overhead crane, grips the panel face, and lets one operator place a 440 lb board precisely onto a saw table.

Two independent vacuum circuits each carry the full rated load on their own. That is not a marketing line: it means a hose failure or a seal breach on one circuit leaves the load still held by a circuit rated to hold it alone, which is the specification difference between this and single-circuit imported lifters at a similar price.

Key features

• Two fully independent vacuum circuits, each rated to hold the full load alone
• Dual batteries for extended run time and hot-swap changeover
• Multiple lifting eyes for crane, jib or gantry mounting
• Integrated set-down legs that protect the pads between lifts
• Audible and visual low-vacuum alarm ahead of the safe limit
• Vacuum reservoir holds the load if power is interrupted
• Non-marking pad seals suitable for pre-finished and gloss faces
