A flexible sling includes two oppositely disposed attachment points defining a first end and a second end of the sling, and an elongate flexible body extending in a lateral dimension from the first end to the second end, the body having a top side and a bottom side. Each of the top side and the bottom side includes a center line marking a center of the body, a first pair of lines symmetrically disposed about the center line, a second pair of lines symmetrically disposed about the center line between the first end and the second end, and the first pair of lines, and a third pair of lines symmetrically disposed about the center line between the first end and the second end, and the second pair of lines.

A lifting device for lifting a cover from a barge includes a main frame and one or more latch assemblies mounted to the main frame. Each latch assembly includes a hook for engaging an eyelet of the cover and an actuator for moving the hook into engagement with the eyelet. The lifting device further includes one or more indexers mounted to the main frame and/or the one or more latch assemblies for locating the main frame relative to the cover and/or the barge in a fore and aft direction of the barge and/or a side-to-side direction of the barge without the need for manual contact with the lifting device, the cover, or the barge.

The present invention relates to a lifting apparatus, in particular a modular lifting apparatus that can be assembled about an item to be lifted. The lifting apparatus has at least two elongate bars connected and spaced apart by at least two spacers; and at least four end plates that are fitted to ends of the elongate bars using a locking mechanism.

Each elongate bar passes through or under an item to be lifted and projects from each end of the item to be lifted; each spacer is shaped and dimensioned to have a portion that extends to abut the item to be lifted and prevent the spacer moving along the elongate bars, and the spacer has a pair of eyes, each eye receives an end of an elongate bar.

Each end plate is locked to the elongate bar by the locking mechanism thereby fixing the spacer in position; and each end plate includes a means for engaging with a lifting device.

Sling bars, lift systems, and methods of attaching a subject sling to a sling bar are disclosed. A sling bar includes a bar extending in a longitudinal direction, a protrusion extending from an upper part of the bar, a sling attachment portion extending to define a receiving aperture, a terminus of the sling attachment portion facing the protrusion, defining an opening into the receiving aperture, the protrusion defining an undercut portion of the receiving aperture, a retention latch pivotally coupled to the protrusion and defining an engagement face that selectively interfaces with a stop surface at the terminus in a closed position to cover the opening, the retention latch being constrained to pivot to an open position whereby the retention latch ceases to interface with the stop surface at the terminus, and a biasing mechanism coupled to the retention latch to force the retention latch toward the closed position.

A lifting beam for suspending an object to be lifted in a vertical direction has a lower end surface extending in a longitudinal direction of the lifting beam on a vertical lower side in a state where the object is suspended. The lower end surface includes a first lower end portion, a second lower end portion positioned away from the first lower end portion to a first side in the longitudinal direction, and a third lower end portion positioned away from the first lower end portion to a second side in the longitudinal direction, on the opposite side of the first lower end portion from the second lower end portion. The second lower end portion is positioned higher than the first lower end portion, and the third lower end portion is positioned lower than the second lower end portion when the object is suspended from the lifting beam.

A lifting apparatus clamps around the sides of a gang box to facilitate lifting and transporting the gang box. The lifting apparatus has a pair of lifting brackets a set of mounting points and a lateral clamp. The mounting points are support protrusions that extend from the lifting brackets to facilitate affixing the lifting apparatus to the bang box. The lateral clamp is connected in between the brackets and provides the force required to clamp the lifting apparatus around the gang box. Thus preventing the lifting brackets from becoming dislodged from the gang box

A lifting frame for lifting a transformer or reactor is provided that includes a frame wall section. The frame wall section extends within a frame wall section plane. A lifting opening is formed within the frame wall section, wherein a lifting opening axis is oriented normal with respect to the frame wall section plane. The frame wall section immediately surrounding the lifting opening has a thickness that increases with decreasing distance to the lifting opening axis. This construction allows for providing an edge of the lifting opening with a comparatively large surface or contact area, while avoiding an overdesign of the frame wall section thickness. An increase in the surface of the edge generally reduces a contact pressure.
