CAT CLASS: HQ-10388

6+ ton Rigging Sling

The 6+ ton rigging sling class comprises heavy-duty synthetic and wire rope slings engineered for crane picks involving structural steel, pressure vessels, and heavy machinery. With lifting capacities ranging from 6.0 to 21.6 tonnes, this top-tier band handles the most demanding industrial rigging applications. Below this band, 2–6 ton slings serve general construction and equipment handling.

Spécifications clés

Spécification	Plage typique	Signification
Lifting capacity	13,228–47,620 lb (6–21.6 t)	Maximum rated load in vertical hitch configuration; capacity reduces in basket and choker hitches per rigging geometry
Load capacity	13,228–47,620 lb (6,000–21,600 kg)	Working load limit expressed in kilograms; identical capacity expressed in metric units
Hitch configurations	Vertical, choker, basket	Common rigging arrangements; each hitch type applies a different de-rating factor to the vertical capacity

Comment choisir

This band is appropriate for crane picks involving structural steel beams, process vessels, generators, transformers, and other machinery exceeding 6 tonnes. Rigging plans for heavy industrial assembly, plant shutdowns, and infrastructure projects typically specify slings in this capacity range. For general construction equipment, steel bundles under 6 tonnes, and standard machinery moves, the 2–6 ton band offers sufficient capacity with easier handling. Load weight, hitch geometry, and D:d ratio (load diameter to sling diameter) all factor into selecting the correct sling from this class; engineered rigging plans often call for multiple slings in tandem to distribute loads safely.

Ce que cette taille peut gérer

Lifting prefabricated bridge girders onto abutments during highway construction
Rigging process vessels and heat exchangers in petrochemical plant turnarounds
Setting large generators and transformers in substation and power plant installations
Hoisting structural steel columns and trusses for high-rise and industrial buildings
Moving injection molding machines and heavy CNC equipment during plant relocations
Handling railway locomotives and rolling stock components in maintenance facilities

Sécurité et opération

Inspect slings before each use for cuts, abrasion, heat damage, and worn or broken yarns in synthetic slings or broken wires in wire rope
Never exceed the sling's working load limit; apply appropriate de-rating factors for choker (typically 75%) and basket (varies by angle) hitches
Protect slings from sharp edges using corner protectors or softeners to prevent localized stress and premature failure
Remove damaged slings from service immediately and follow manufacturer retirement criteria and ASME B30.9 standards for rigging hardware

Transport et logistique

Heavy-capacity slings transport coiled or bagged in pickup beds, service vans, or rigging trucks alongside shackles and spreader beams
Wire rope slings in this class may weigh 50–150 kg per sling depending on length and diameter; handled manually or with hoists during staging
Rigging packages for large crane picks often arrive on flatbed trailers with multiple slings, blocks, and below-the-hook gear

Alimentation

Rigging slings are passive lifting devices requiring no electrical power or fuel
Crane or hoist providing the lifting force typically operates on diesel, hydraulic, or three-phase electric power
On-site power needs are determined by the prime mover (crane, gantry, or winch) rather than the sling itself

Questions fréquentes

How does hitch configuration affect the working load limit of a 6+ ton sling?

Vertical hitches use the full rated capacity. Choker hitches typically reduce capacity to 75% of vertical rating. Basket hitches depend on the sling angle; a 60° basket may double the vertical capacity, while smaller angles reduce it. Manufacturers provide hitch-specific load charts for each sling.

What is the difference between synthetic and wire rope slings in this capacity class?

Synthetic slings (nylon, polyester) are lighter, more flexible, and less damaging to finished surfaces, but are vulnerable to cuts, heat, and UV degradation. Wire rope slings tolerate abrasion and high temperatures but are heavier, stiffer, and can damage polished or painted loads. Selection depends on load surface, environment, and rigging geometry.

When are multiple slings required instead of a single high-capacity sling?

Engineered lifts often distribute loads across multiple attachment points to maintain balance and reduce stress on the load structure. Rigging plans specify sling quantity, placement, and individual capacity based on load geometry, center of gravity, and lift dynamics rather than total weight alone.
