What has to be taken into account when selecting chains?
RUD supplies chains in different diameters, qualities, lengths and in the highest material class. In 1994, RUD was the first chain factory to be awarded approval by the employers’ liability insurance association for VIP special grade (Grade 10) with up to 30 % greater WLL than Grade 8. In addition, RUD was the first chain factory to be awarded approval for round steel chains of Grade 12 (ICE 120) from the employers’ liability insurance association in 2007.
Thanks to its unique product and material portfolio, RUD can supply the matching solution for every purpose of application. This wide range of lifting means is guaranteed by the material qualities ICE (Grade 120) and VIP (Grade 100).
Before a decision is made regarding a chain lifting means, the following questions should be answered:
What usage height do I have available and what is the maximum lifting means length?
What working environment is the lifting means used in (temperature, rough environment, handling, ...)?
RUD ICE chains.
ICE stands for Innovative Chain Evolution. RUD ICE chains are lifting means of Grade 12 and represent a (r)evolutionary advanced development in the lifting means segment. Their colour code is ICE-pink (traffic purple).
RUD ICE chains have been tested and certified by the certification authority of the committee of metal and surface treatment of the employers’ liability insurance association Metal North South (BGM) and also approved with the quality grade stamp "D1-12" (D=Degree of Quality / 1=Manufacturer RUD / 12=Grade). RUD ICE-120 chains and components have been designed for 20,000 changes in load (tested with 50 % overload) in accordance with DIN EN 818 and 1677 for dynamic load.product details
A decisive ICE advantage – always one nominal thickness smaller than Grade 8.
On account of the extremely high material strength of the patented ICE material, RUD has managed a continuous shift in nominal thickness compared with Grade 8 even for thinner diameters ≤ Ø 16 mm. In practice, this means that an ICE lifting or lashing chain – no matter the nominal thickness – can replace a Grade 8 chain of the next-higher nominal thickness. The resulting reduction in own weight of more than 30 % is a major advantage for work ergonomics.
Whether hot or cold – ICE is the best.
Thanks to their extreme temperature resistance of –60 °C to +300 °C, ICE chains are suitable for Polar and Arctic applications as well. Their brittle fracture transition temperature is < –70 °C.
High value for money thanks to special ICE hardening.
Whether hot or cold: during tough use of the ICE chain, particularly when moving sectional steel (e.g. during port handling or construction work when used as a choke hitch) the patented material and special RUD ICE hardening result in economic advantages. Damage to the chain cause by edge deflection is significantly reduced compared to a chain with a lower material strength.
Non-mix-up in pink: RUD VIP chains.
RUD VIP chains in their colour code Pink are a consistent further development of the tried and tested RUD modular system in Grade 8 that has been on the market for more than 30 years. The special fluorescent pink powder coating changes its shade permanently at higher temperatures. Thus deep black is a sign of temperature above 380 °C; further use is no longer permitted. RUD was the first manufacturer to receive the type testing certificate for VIP round steel chains in accordance with PAS 1061 (Publicly Available Specification = supplement to the standards of the series DIN-EN 818 Grade 10) and the first to receive approval for H1-10.product details
When the going gets heavy, we make things easier.
From a chain diameter of 20 mm, there is a change in quality grade from ICE chains to VIP chains. The highly dynamic VIP modular system and the VIP chains are above the standard values in their dynamic strength. Their minimum load cycle figure is over 20,000, the maximum load for VIP components is 1.5 times the VIP WLL. This allows loads of up to 126 t to be lifted and moved, or even larger ones when special components are used.
