Vacuum lift attachment

A vacuum lift attachment for a hydraulic work machine having a control station, a lift arm to which a hydraulic work attachment can be coupled;

• the vacuum lift attachment comprising:
• a body having an upper end having connecting a pair of connecting pins for coupling to a quick hitch on the lifting arm of the hydraulic work machine;
• a hydraulic rotator mounted to the lower end of the body;
• and
• a vacuum pad mounted to the hydraulic rotator for rotation relative to the body that is operable between a suction position and a release position.

A vacuum lift attachment for a hydraulic work machine having a lift arm to which the vacuum lift attachment can be coupled, the vacuum lift attachment comprising:

• a body having an upper end that is adapted to be coupled to the lift arm of the hydraulic work machine;
• a vacuum pad mounted to the lower end of the body;
• a vacuum pump in fluid communication with a first service vacuum reservoir;
• an air valve operable between an open position in which the first service reservoir is in fluid communication with the vacuum pad so as to apply a vacuum thereto and a closed position;
• and
• a second reserve vacuum reservoir that is fluidly isolated from the vacuum pad when the vacuum pad is carrying a load at or above a predetermined vacuum level, and if the vacuum level falls below the predetermined level a second air valve is actuated to fluidly connect the reserve vacuum reservoir to the vacuum pad.
