Lifting Beams are ideal where there is insufficient headroom for a top suspension sling and the top lifting point is usually a centre lifting eye. The lower lifting points are most commonly found at the outer extremities of the beam and intermediate lifting points, often adjustable are also common place for lifting longer loads that need support over their length. Size for size, Lifting beams will be considerably heavier and more expensive to manufacture than Spreader Beams as they have to be of a sufficient section and strength to sustain the cantilever forces produced by the lifting of the load.

Eyebolts with link which can be hooked into directly, offer considerable advantages over collared eyebolts when loading need to be applied at angles to the axis and/or the plane of the eye. Their SWL's are relatively greater than those of collared eyebolts used in the same condition and, unlike the collar eyebolt, the load can be applied at any angle to the plane of the eye. Eyebolts with link may be loaded in any direction up to the marked SWL, provided that the angle of the load to the axis of the screw thread of the eyebolt does not exceed 15°. Eyebolts with link may be used for non-axial loading at inclinations greater than 15° provided the SWL is appropriately reduced (see table 8; BS4278:1984.).

Long link chain should not be used for lifting purposes and the pitch (inside length) can vary quite considerably (5-8 times) dependant upon the specification/manufacturer.
