RUD ICE Grade 120 Round Link Chains - Changing the future of chain sling systems

In 2007 RUD added a round link grade 120 chain to its product offerings. RUD’s ICE chain (Grade 120) is also manufactured using the highest quality patented fine grain steel that has been specially heat treated for increased strength and toughness. RUD’s grade 120 chain has up to 60% increase in working load capacity in comparison to grade 80 chains. This increase in strength allows the reduction in chain size for lifting heavier loads. RUD ICE chain has also been designed to withstand extreme temperatures, from -76°F (-60°C) up to 572°F (+300°C). ICE chain is available in sizes 4 mm (<3/16”) through 16 mm (5/8”). In 2007 RUD received approval from the certification authority of the committee of metal and surface treatment, BG Metal Nord Süd, to stamp the grade 120 ICE chain with the new grade stamp "D1-12" (D=Degree of

Quality / 1=Manufacturer RUD / 12=Grade).

RUD’s grade 120 ICE chain offers the same heat-indicating powder coating technology as the Grade 100 VIP chain, but the ICE chain has a more purple hue to its powder-coating; just like the VIP chain, the ICE chain changes colors to indicate the temperatures to which the chain has been exposed. The purple color will start to change to a brown at 482°F (250°C). The chain cannot be used in temperatures at 572°F (300°C) or above, or it will turn from its pink color to brown. Each color change will also indicate that the working load limit has decreased, and this will need to be considered if the chains are still being used for overhead lifting. If the powder coating changes to black, this color change indicates that the chain has been subjected to enough heat to compromise the integrity and strength of the chain; at this point the chain is unsafe to use and must be taken out of service. RUD ICE lifting chain is often used for projects located in harsh environments and arctic regions due to its extreme resistance to temperatures.

RUD sling systems also have RFID technology. RUD embeds a RFID chip into all of their chain slings and the components so that they can be effortlessly and quickly identified without errors. The Product Identification Number can be easily registered and managed and read with RUD's RUD-ID-EASY-CHECK® readers and the RUD-ID-NET® software.
