A quick release weight retaining device may include a grapple which may be removably engaged to a retainer. The grapple may include a seat and an ejector, and the retainer may include an arm. The grapple may be coupled to objects, such as a lifting bar, preferably via a securement fastener. The retainer may be coupled to objects, such as weight plates and the like, via a retainer body and a weight saddle. The arm may rest in the seat and be maintained therein by a desired weight, such as the weight of the weight saddle. When the weight is relieved from the retainer, such as by the weight saddle resting on a ground surface, the ejector may force the arm out of the seat thereby disengaging the grapple and retainer.

The present disclosure is directed to an apparatus, system and method for the delivery of one or more items onto one or more target surfaces including elevated surfaces and inclined surfaces. An apparatus of this disclosure is operationally configured to be moved in space via lifting equipment while carrying one or more items. An apparatus of this disclosure is also operationally configured to direct one or more items onto one or more target surfaces without manual assistance for removing the one or more items off from the apparatus onto one or more target surfaces. Removal of one or more items off from the apparatus may be performed in a controlled and/or programmed manner. The present disclosure includes maintaining one or more items on or more target surfaces once the one or more items are removed from the apparatus.

A lifting clamp for an object comprises a plurality of plates stacked and connected together to form seat for a portion of the object, a lifting portion for connecting to a crane or other machine, a pivot leg pivotally connected to the stacked plates for opening the seat, and a lock for selectively locking the pivot leg in a clamped position whereby it grips the object.

A balanced cantilevered feeding apparatus for coupling with a jib, and a complementary method for its operation, configured to facilitate depositing and removing of a load through an opening in a building. The apparatus includes two spaced apart upright hoisting assemblies disposed on the jib, and a fly beam hoisted, balanced, and selectively positioned along a lateral axis by the two hoisting assemblies. A load securing member is mounted on a cantilevered extension portion of the fly beam, wherein the member extends beyond one of the two hoisting assemblies toward the building, and a counterweight is connected to the fly beam in the vicinity of another of the two hoisting assemblies.
