摘要： 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.
