摘要 |
A vacuum lifting arrangement for flat workpieces, such as wooden boards, wooden beams and the like, includes a vertically and horizontally movable housing bounding a suction chamber having a downwardly open suction side. A valve insert is accommodated in the suction chamber and is preferably removably mounted on the housing. A closing plate is hingedly mounted on the housing for pivoting into an out of a closing position in which it sealingly covers the downwardly open suction side of the suction chamber and the valve insert. An elastic sealing element in the form of a foamed mat having suction apertures is mounted on the closing plate, and is operative for sealingly contacting the workpieces to be lifted.
