Devices and methods utilize a lifting beam comprising at least two connectors with a first connector substantially centered on the beam and a second connector disposed closer to an end of the beam which permit a heavy equipment operator to selectively change the vertical orientation of the lifting beam from a substantially horizontal position to a substantially vertical position. The lifting beam is selectively positionable by the equipment operator downwardly through the top opening of a precast, concrete dome without requiring the operator to leave the protection of the equipment cab. When positioned inside the concrete dome, the lifting beam is oriented substantially horizontally and the concrete dome can be lifted and repositioned by lifting the beam.

The arm with two or more hooks 1 comprises: a supporting beam 1) designed to be connected to an operating arm 20 of a telehandler 2 or another self-propelled operating machine and a plurality of hooks 11, 12, 13, distributed along the beam 10, each designed for supporting a respective load.

One or more hooks 11, 12, 13 are connected to a load sensor 31, 32, 33.

An installation jib for a girder beam installation and removal system includes a main body having a first end and a second, opposite end, the main body extending along a longitudinal axis between the first end and the second end. The installation jib further includes a first sub-frame element coupled to the main body, a first roller coupled to the first sub-frame element, a second sub-frame element coupled to the main body, and a second roller coupled to the second sub-frame element. The first sub-frame element and the second sub-frame element are spaced longitudinally apart from one another, and the first roller and the second roller each are configured to rotate about an axis that is parallel to the longitudinal axis.

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.

The present application includes a compressor having a cylinder forming a compression chamber in which gas is compressed, a housing having a peripheral wall forming an internal space in which the compressor is stored, and a supporting member situated above the compressor in the internal space. The peripheral wall includes an opening wall in which a carry-out port is formed through which the cylinder is carried out. The supporting member extends to guide movement of a first lifting device between a position above the compressor and a position above the carry-out port. The cylinder is hung from the first lifting device.

A tool is provided for removal and installation of a fire tube that extends into an opening in a wall of a heating vessel. The fire tube locates within an interior of the heating vessel when mounted thereto. The fire tube has a tube wall that defines a tube interior and has a mounting end for mounting the fire tube to the wall of the heating vessel. The tool has an elongated main shaft member having an insertion end and an opposite control end. A first support is mounted upon the insertion end that is configured for being closely received within the tube interior. A second support is mounted along the length of the main shaft member, the second support having a fire tube interface configured for engaging and releasably coupling to the mounting end of the fire tube. A lift coupling couples to the main shaft and locates between the second support and the control end of the main shaft member for coupling to a lift line. A counterbalance support carries removable weighting members, the counterbalance support being coupled to the main shaft by a counterbalance support spacing arm that extends laterally from the main shaft member.

A rack and a hoist system. The rack is L-shaped with a first planar floor/leg and a second planar floor/foot, which is a solid plate. The first floor has three pairs of wheels with the middle pair larger than the other pairs and a mount to couple to the hoist via a hooked line that couples to a double-hooked line that hooks into apertures through paired mounting plates near the top end of the leg. The foot includes a tag-line mount from which a tag-line may be mounted to help guide movement thereof using the hoist. The foot includes wheels such that when the first floor is tipped up while being lifted, the wheels of the foot engage with the surface while the wheels on the leg are disengaging. There are flanking posts, strap structures, and flanking plates that help to secure the load (e.g. rebars, pipes, and sheet rock).

The installation jib further includes a first sub-frame element coupled to the main body, a first roller coupled to the first sub-frame element, a second sub-frame element coupled to the main body, and a second roller coupled to the second sub-frame element. The first sub-frame element and the second sub-frame element are spaced longitudinally apart from one another, and the first roller and the second roller each are configured to rotate about an axis that is parallel to the longitudinal axis.

An under the hook lifting device configured to lift an object is provided. The lifting device includes a boom having a first end and a second end, and a strap having a length extending downwardly from the first end of the boom, where the strap is configured to be secured to an object. A winch is positioned on the boom, where the winch is configured to adjust the length of the strap extending downwardly from the first end of the boom. The lifting device also includes a counterweight extending downwardly from the second end of the boom, and a trolley positioned at the second end of the boom, where the trolley is slidable along the boom. The counterweight is supported by and movable with the trolley, where the position of the trolley along the boom is movable to maintain a substantially horizontal position of the boom. Methods of lifting an object with a lifting device are also provided.
