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 present disclosure is directed to a component handling assembly. The component handling assembly includes a base member, an arm pivotably coupled to the base member, and a beam rotatably coupled to the base member. The component handling assembly also includes a counterweight rotatably coupled to a first end of the beam. The component handling assembly further includes a coupling assembly coupled to a second end of the beam. The coupling assembly is configured for coupling to a component. Rotating the counterweight in a first direction rotates the beam, the coupling assembly, and the component in a second direction.

The present invention provides a machine for the aerial handling of a load. The machine comprises a bearing slide, an aerial suspension device slidably mounted on the bearing slide, a coupling and dragging device for coupling and dragging the load on the bearing slide, an actuator for a longitudinal movement of the support plate along the bearing slide, so as to continuously balance possible oscillations due to weight shifting during load handling operations, and load supporting and stabilizing elements provided along the bearing slide. The aerial suspension device includes a support plate slidably mounted below the bearing slide, a support structure formed integral with the support plate and having an interior allowing a passage of the load, and a suspension element for suspending the machine to a 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 tube wall that defines an 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 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 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.

In the field of hoisting and controlling hoisted loads, a hoisting device for hoisting a load includes a support beam, two load carrying units, structured to be slid along the support beam and being structured to hold the load, at least one counterweight structured to be slid along the support beam, at least one sensor capable of measuring the weight force held by the load carrying units, a first driving unit structured to slide the load carrying units, a second driving unit structured to slide the counterweight, a third driving unit structured to hoist the load, a hooking point structured to be hooked from a crane, and a processing unit structured to receive the information produced by the sensor and structured to operate the first driving unit, the second driving unit and the third driving unit.

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.

A device comprising a weldment having an upper beam, a vertical beam, and a lower beam, wherein the upper beam further comprises at least two lifting eyes and at least one crane hook, and the lower beam further comprises a plurality of swivel-hoist rings and a plurality of forklift pockets, and wherein the lower beam is a length minimally required to locate a structure laterally underneath an upper level of a platform having an upper level and a lower level.

A system includes a spreader bar comprising a structural support, a first load coupling, and a second load coupling, and a lift coupling and a drive system coupled to the lift coupling. The system also includes at least one load sensor configured to sense a load coupled to the first load coupling, the second load coupling, or a combination thereof. A controller may be coupled to the drive system and the at least one load sensor, such that the controller is configured to obtain an indication of a center of gravity of the load based on the at least one load sensor, and the controller is configured to operate the drive system to move the lift coupling based on the center of gravity.
