With the Carl Stahl chain sling configurator, you can design your chain sling precisely for your application — in just six easy steps. From single-leg to four-leg slings, with or without a wreath/auxiliary chain: the configurator guides you through every option — including a 3D view, WLL verification, and component comparison.
Your benefits at a glance:
- Guided 6-step process with safety notices according to DGUV 100-500 / 109-017
- Interactive 3D visualisation
- Selection by working load limit, number of legs, and effective length
- Compare components (e.g. shortening elements, connectors, hooks)
VIP or ICE – what’s the difference?
In the configurator you can choose between two high-performance RUD technologies: VIP (Grade 10) and ICE (Grade 12). Both stand for top quality, safety, and traceability. The following guide helps you select the right option.
VIP – Grade 10: the robust all-rounder
- Up to 30% higher WLL compared to Grade 8 at the same chain diameter
- Considerably lighter due to optimised chain dimensions and material strength
- Exceptional toughness thanks to specially tempered CrNiMo alloy steel
- Durable pink powder coating with heat indicator (changes colour above 200 °C)
- DNV-approved for marine, industrial and offshore applications
- Outstanding wear resistance through RUD’s precision heat-treatment process
ICE – Grade 12: maximum performance at minimal weight
- Up to 60% higher breaking force than Grade 8 — ideal for heavy loads
- Roughly 30% lighter, providing ergonomic handling and improved safety
- Temperature-resistant from –60 °C to +300 °C for extreme operating environments
- High surface hardness and wear resistance through special ICE hardening
- Suitable for extreme conditions: cold, heat, sharp-edged loads
- Resource-efficient and sustainable thanks to optimised alloy and energy use
Conclusion:
VIP is the proven choice for versatile applications with dynamic loads. ICE is ideal when you work in particularly harsh or extreme conditions — and value low weight with maximum breaking strength.

Configurator highlights at a glance: what to keep in mind
The configurator guides you step by step to a safe selection. For planning, operation, and inspections, please note:
1. Load weight
The weight to be lifted is the basis of any design. Only an accurate weight (including attachments) allows you to determine the safe WLL.
2. Number of legs & symmetry
Up to four legs are possible. The number depends on attachment points, symmetry, centre of gravity, and load geometry. For unsymmetrical loading, the WLL of a single leg applies (DGUV 100-500).
3. Effective length & sling angle
Effective length determines the sling angle (permitted 0°–60°). A larger distance between attachment points requires longer legs. The configurator checks angles and shows WLL depending on angle.
4. Centre of gravity & geometry
For asymmetrical or elongated loads, different leg lengths or additional components (e.g. wreath/auxiliary chain) may be required. Observe any WLL reductions.
5. Operating environment
Temperature, cold, moisture, or edges influence the choice of grade. ICE components are suitable, for example, from –60 °C to +300 °C; sharp-edged loads require suitable edge protection.
6. Safety, combinations & prohibitions
Only combine components of the same grade/nominal diameter. Knots, twists and choking with hoist chains are not permitted. The configurator flags incompatibilities and guides you to a safe selection.
