A crawler frame has a crawler frame outer surface that is opposite to a surface via which the crawler frame is attached to a traveling body main part in the left-right direction. A bracket includes an attaching part, a circuitous part, and a crawler lifting section. The attaching part is attached to the crawler frame outer surface. The circuitous part is partially arranged below and above a crawler belt on an outer side thereof in the left-right direction, and extends around the crawler belt. The crawler lifting section is connected to the circuitous part and arranged above the crawler belt for receiving the crawler lifting tool.

A C-gripper for arranging at a cross-member or at a suspension element and a cross-member having at least one such C-gripper for for handling a load, formed from an upper strut, a vertical strut and a support strut which forms a so-called hook base, onto which the load can be placed. The upper strut and the vertical strut are, as with conventional constructions, rigidly connected to one another and substantially arranged at right angles to one another. Other angles likewise lie within the framework of the invention. However, the support strut is not rigid, but rather connected in a rotatably mounted manner to the vertical strut and, indeed, in such a manner that a clear dimension (h) of a mouth of the C-gripper can be modified, that is to say can be increased or decreased. Moreover, the vertical strut is telescopable. It is thus configured as a telescopic strut.

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.

An apparatus for lifting elongated objects includes a shelf that is elongated, and a frame connected to a lengthwise edge of the shelf for lifting the shelf and any panels that are resting on the shelf. The frame includes risers affixed to the shelf and extension members that extend from the risers over the shelf. Shackles are mounted to the extension members at a location (center of gravity) that keeps the apparatus for lifting elongated objects substantially level when lifted by cables attached to the shackles. Telescoping extensions at each end of the shelf provide for lifting longer elongated objects (e.g., the shelf is 30 feet long when the telescoping extensions are retracted and 50 feet long when the telescoping extensions are completely extended, providing for lifting very long elongated objects (e.g., 100 foot long or greater elongated objects).

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.

A suspension ring for multistrand lifting tackle comprises two parallel rectilinear legs connected to one another at their ends by arcuate connecting legs. A lower connecting leg is along a longitudinal center line of the ring, extending as a circular segment in the central region of its extent and in the two regions in which it merges into each of the two legs. The radii of the rounded portions on the inside of the ring are less than half the internal width of the ring but greater than half the diameter of the legs, and the central region in the form of a circular segment is connected at its ends to the transitional region as a circular segment to the adjacent leg via a rectilinear intermediate segment of the connecting leg. An angle of the intermediate segment ranges from 50 to 75 to the longitudinal center line of the ring.

A system for transferring objects into a device inside a controlled environment includes a winch, tool and carousel. The winch includes a drum, and wire arrangement configured to be reversibly wound onto the drum by a first drive. The tool is suspended below a distal end of the wire arrangement and configured to suspend an object. Both the tool and the object are sized to fit inside a device located below the winch. The carousel is connected to a second drive configured to rotate the carousel around a vertical axis, and includes a storage space centered at a first horizontal angle and a pass-through opening at a different second horizontal angle. The pass-through opening being large enough to pass the tool and the object as the wire arrangement is unwound from the drum thereby lowering the tool and object inside the device.
