<p>A vacuum based lifter device for displacement of an article (33; 34), wherein at least one suction plate (2) or suction cup (28) is designed (5) to be connected to and disconnected from a vacuum source (22, 23, 23', 17), and wherein the suction plate (2) or suction cup (28) is secured to equipment (6-12) in order to be able to move it together with or relative to said article (33; 34) which it to be displaced. The device has a pallet-like structure (21, 21', 22, 23, 23', 29, 29') into which there can be inserted fork members (30, 30') which are mounted on a fork-lift truck (31), and wherein parts of the structure define a vacuum chamber (22, 23, 23'), a vacuum source having an electrically driven vacuum pump (17) provided on the pallet-like structure and pneumatically connected to the vacuum chamber (22, 23, 23'), and a mechanically or electrically controllable stop and release valve (5) which is pneumatically coupled (4, 4', 3, 3') between the vacuum chamber (22, 23, 23') and said suction plate (2) or suction cup (28).</p> |
