A below-the-hook vacuum lifter that features C-clamp construction with an adjustable bail for picking up loads from the inside, where the top is inaccessible, is by Anver Corp, Hudson, MA.

The Anver Custom C-Clamp Vacuum Lifter was developed for handling loads from the inside and includes an adjustable bail for achieving the proper balance. Featuring an attach/release valve, a check valve to maintain vacuum, and a vacuum gauge, the electric powered vacuum lifter lets the operator put the load down safely in case of a power failure.

Suitable for assembly and packaging tasks, the lifter conforms to ASME Standard B30 20a-2010 for vacuum lifting devices and has a continuously running vacuum pump that lets it perform well on slightly porous material. Applications include cabinets and instrument enclosures.
