Abstract: The present invention is a lifting apparatus that includes a master wedge bar, a slave wedge bar, a cam lug and a handle. The master wedge bar and slave wedge bar are configured to be placed in a drilled core in an object to be lifted. The cam lug is pivotally coupled to the master wedge bar and drivingly engages with the slave wedge bar such that upward force applied to a lift end of the cam lug drives the slave wedge downward. The master wedge bar and the slave wedge bar generate an outward force upon the core wall of the object upon the downward movement of the slave wedge bar relative to the master wedge bar such that the apparatus engages the core wall and secures itself in it by friction. A handle is configured to disengage the apparatus from the core wall when lifted upward.

Abstract: A backpack (160) with an air frame (162). The backpack includes a storage compartment, an air frame (162), and at least one strap (168) for securing the bag to a person. The air frame (162) includes an air bladder, which stiffens as it is inflated. The air frame (162) may include portions that are individually inflatable, and a pump (26) may be included for inflating the air frame (162). The backpack (160) may include inflatable portions (22) designed to provide support to specific portions of a user's body.

Abstract: A fork and jaw grapple attachment having two forks and a jaw for wedging under, prying up, gripping, moving and handling materials. The forks have tips with angles for prying between and under materials. The jaw being a hydraulically actuated upper jaw that moves about a pivot point via a cylinder for grabbing, gripping and holding materials during pick-up, transport and place down.
