A vacuum gripper comprises a rigid base element and a loop-shaped vacuum seal element. The base element has first and second opposite sides. The seal element is attached at least indirectly to the second side and protruding therefrom in a direction away from the first side. The seal element comprises a contact surface that at least partially contacts with an object surface and an encircling surface oriented transversely to the contact surface so as to define a chamber. The seal element is elastically deformable at the contact surface to enable conforming to the object surface when pressed thereagainst. The vacuum gripper comprises an air extraction means mounted to the first side to be in fluid communication with the chamber through the base element, and configured to continuously extract air from the chamber to cause the contact surface to be urged towards and grip the object surface when pressed thereagainst.

Embodiments of a vacuum material handler or lifting device and system of this disclosure provide a modular design that allows a power pack to be mounted directly to the pad or remotely mounted on host equipment to minimize lift weight. The pad, which includes an integral, pad reservoir, may be arranged, to accept a rotator or a tilting mechanism for position when used on mobile equipment. The power pack is independent of the pad and can be transferred to multiple pads, thereby permitting a single power pack to service the different pads. The control mechanism may reside on the pad to further facilitate modularity. Safety checks used for remote operation may be used to minimize the risk of danger in the event of remote vacuum hose or vacuum failure.

A slab handling system provides an accessory that can be configured to secure vacuum grippers to a beam. The accessory includes a body having a passageway therethrough for receiving the beam. The body further including slots on either side of the passageway that are configured to receive connectors of a vacuum gripper. In one embodiment the accessory can also be configured as a height-adjusting device. In one embodiment the accessory can also be configured as a traction device. The height-adjusting device and the traction device may be used in conjunction with the accessory and vacuum grippers to facilitate handling of one or more slabs.

A material lifter comprising a vacuum pump, a frame containing the vacuum pump, an arm located on each of two opposing sides of the frame, each arm including an upper end pivotally connected to the frame, a cylinder located on each of the two opposing sides of the frame including an end connected to the frame and an end connected to a respective arm, a vacuum pad located on each of the two opposing sides of the frame and removably connected to a respective arm, the vacuum pads being moveable along the arm to a first location and a first orientation and a second different location and a second different orientation, wherein as the cylinders extend and retract the arms pivot toward and away from one another between a first position and a second different position and the vacuum pads remain in a same orientation during the pivot.

A vacuum material handler (10) has a vacuum beam (12) supported by an adaptor block (60) attached to a rotator (50). A vacuum pad (40) is carried beneath the vacuum beam (12). The vacuum beam (14) has a motor (20) that powers a pump (30). The adaptor block (60) has a body (64) and arms (70/71) having receivers thereon for receiving an upper pin assembly that may be carried by host equipment. The host equipment locates foe upper pin assembly within foe receivers where the upper pin (66) may be clamped into place, thereby conducting all heavy lifting with foe host equipment.

Battery gripper (12), for attracting by suction and handling starter batteries (26) of, in particular, motor vehicles, having a housing (56), in which a vacuum chamber which can be loaded with vacuum is provided and which has suction openings (84, 84) on the suction side thereof (54) which faces the starter battery to be attracted by suction, wherein the suction side is assigned a flexible lining (82) for contact with the starter battery, wherein the housing has a T-shaped cross section which runs parallel to the suction side, wherein the cross section has a bar section (64) and a web section (66) which extends transversely from the bar section, in such a way that the web section extends between the battery poles (68, 70) of the starter battery when the starter battery is attracted by suction to the battery gripper.

The present disclosure is directed to a lifting device for a rotor blade of a wind turbine. The lifting device includes at least one cradle and a vacuum sealing system configured with the cradle. The cradle has a profile that corresponds to at least one of the exterior surfaces of the rotor blade so as to support at least a portion of the rotor blade. The vacuum sealing system is configured to secure the rotor blade to the cradle as the rotor blade is lifted and/or lowered from a hub mounted atop a tower of the wind turbine.

A material lifter comprising a vacuum pump, a frame containing the vacuum pump, an arm located on each of two opposing sides of the frame, each arm including—an upper end—pivotally connected to the frame, a cylinder located on each of the two opposing sides of the frame including an end connected to the frame and an end connected to a respective arm, a vacuum pad located on each of the two opposing sides of the frame—and removably connected to a respective arm, the vacuum pads being moveable along the arm to a first location and a first orientation and a second different location and a second different orientation, wherein as the cylinders extend and retract the arms pivot toward and away from one another between a first position and a second different position and the vacuum pads remain in a same orientation during the pivot.

Aspects described herein include an end effector capable of prehending items using impactive and astrictive forces. The end effector includes an interface system having a deformable mounting plate and a pliable body member attached to the mounting plate. The end effector further includes a linkage system between a plurality of actuators and the interface system. The linkage system connects to lateral portions of the mounting plate.
