Abstract: A traffic barrier lifter mountable on a boom and having a gearbox with a first and a second rotating axis; a pair of opposing arms directly mounted to the first and second rotating axis and a rotator capable of rotating the lifter relative to the boom, wherein the gearbox is capable of moving the pair of opposing arms from an open position to a closed position such that the arms can clamp onto a traffic barrier. The rotator being capable of rotating the arms and traffic barrier relative to the boom.

Abstract: A system and method for moving directional drill pipe with vacuum power. The system is used with a vacuum beam mounted on a boom. It has a vacuum pad that is pivotally attached at one end by a hinge to the vacuum beam. The other end of the vacuum pad is attached to the vacuum beam via an actuatable cylinder. Operation of the cylinder causes the vacuum pad to rotate about the hinge and change the angle of the vacuum pad relative to the vacuum beam. Lateral movement of the vacuum pad relative to the vacuum beam is provided by one or more pinned connections located adjacent to the hinge. Vacuum pressure from the vacuum pad is used to grasp and release drill pipe.

Abstract: A traffic barrier lifter having a pair of opposing arms carrying a vacuum pad. An articulating mechanism opens and closes the opposing arms such that the vacuum pads can clamp onto a traffic barrier. Each pad equipped with one or more vacuum reservoirs. These reservoirs are in fluid communication with a vacuum source. The vacuum line running from the reservoir to the vacuum source has a check valve. In the event of a power failure to the vacuum source or failure of the vacuum source itself, the check valve closes to maintain vacuum in the reservoir. The traffic barrier lifter being attachable the boom of an excavator or other appendage of a piece of heavy equipment.

Abstract: A blade row for a rotary machine includes a radially inner endwall, a radially outer endwall having a radially inner surface, and an airfoil including a root section coupled to the inner endwall and a tip section coupled to the outer endwall such that the airfoil extends radially between the inner and outer endwalls. The radially outer endwall includes a projection extending radially inward from the outer endwall inner surface such that the outer endwall inner surface includes a non-axisymmetric shape.
