Crane Accessories

Crane accessories, in rigging terms 'below-the-hook lifting devices,' are the equipment that sits between a crane's hook and the load itself: replacement or upgraded hooks, spreader and lifting beams that spread a load across multiple pick points, and lifting eyes or eye bolts fitted permanently or temporarily to the load. None of it moves the load on its own the way a crane does, but a wrong or worn piece here fails the lift regardless of how capable the crane is, which is why this category is engineered and rated as carefully as the crane's own load chart.

NLS sources three main categories. Crane hooks, whether a standard shank hook or a self-locking swivel hook, are rated by capacity and required to carry a safety latch that keeps a sling from slipping off under slack-line conditions, manufactured and inspected to ASME B30.10. Spreader beams and lifting beams turn a single crane hook into two or more pick points spaced to a load's actual lifting points, either as a fixed-geometry beam for a repeat lift or an adjustable beam for varying loads, and they're engineered devices, not generic steel sections, sized to the load and span. Lifting eyes and eye bolts, including swivel and shoulder types, provide a fixed, rated attachment point on the load itself. All three fall under ASME B30.20, the standard covering below-the-hook lifting devices, which sets design, marking, and inspection requirements distinct from the sling or shackle standards.

On Saudi projects, spreader beams and multi-point rigging show up wherever a single load, long structural steel members, precast panels, HVAC skids, has multiple lift points that a single sling angle can't safely reach without overloading one leg. Below-the-hook devices are typically engineered for a specific load and lift plan rather than picked from a general catalog, since a spreader beam sized for the wrong span or capacity defeats the purpose of using one.

NLS quotes crane accessories against the required capacity, lift geometry (number and spacing of pick points), and hook or attachment type, and returns a priced quote in USD. Standard hooks and eye bolts typically source faster than engineered spreader or lifting beams, which are more often built to order against a specific lift plan with a manufacturer-confirmed lead time.
