A vacuum lifting device to facilitate the lifting and/or repositioning of an article having an external surface as set out herein comprises at least one pair of handles and a base having opposed first and second surfaces, the base having an aperture arranged through the base. The second surface is arranged is provided with a continuous sealing joint projecting downwards from the second surface defining an enclosed area which includes the aperture on the bottom surface of the base. The vacuum lifting device also comprises a suction conduit arranged to be connected to a vacuum generating member and configured to be in fluid connection with the second surface of the base through the aperture. The vacuum lifting device further comprises an extendable lifting member arranged between the at least one pair of handles and the first surface of the base, the lifting member is actuated by a lift actuating member for shifting the base in a vertical direction transferring said vacuum lifting device (10) between an extended and a compressed state. A method for using the vacuum lifting device is also disclosed.

A vacuum lift attachment (10) for a hydraulic work machine, the hydraulic work machine including a control station, a lift arm to which the hydraulic work attachment can be coupled, an auxiliary hydraulic system for operating a coupled hydraulic work attachment and an auxiliary hydraulic actuator in the control station that upon actuation by an operator causes an auxiliary hydraulic control signal to generate. The vacuum lift attachment comprises a body (12) having an upper end (13) that is adapted to be coupled to the lift arm of the hydraulic work machine and for hydraulic fluid connection to the auxiliary hydraulic system of the hydraulic work machine, a vacuum pad (20) mounted to the lower end of the body (10), a hydraulic vacuum pump (34) fluidly connected to the auxiliary hydraulic system and an electronic controller (26) that is configured to receive an auxiliary hydraulic control signal and convert the auxiliary hydraulic control signal to an electronic signal for electronic control of the hydraulic vacuum pump (20) by an operator actuating the auxiliary hydraulic actuator in the control station.

The paver moving tool (10) includes a suction head (12), a shaft (24) secured to the suction head (12), a lift-handle (30) secured to a top end (28) of the shaft (24), and one of a first and a second rechargeable vacuum power pack (34, 50) operably coupled in fluid communication with the suction head (12) for selectively applying a vacuum force through the suction head (12) to an adjacent paver (20). The rechargeable vacuum power packs (34, 50) are supported on either the shaft (24), the lift handle (30) or on a backpack (53) on an operator of the self-powered paver moving tool (10) while the operator is using the tool (10).
