DoComfort lifting chains in Grade 10 have increased load capacities compared to lifting chains of grade 8. The chain material consists of a special alloy and is therefore more wear-resistant, particularly tough and results in a 25% higher load capacity compared to lifting chains of grade 8 or, with a comparable load capacity, an even lower dead weight. The dimensions and shape correspond to those of grade 8. DoComfort lifting chains are suitable for hot use up to 400° C (please note loss of load capacity!).
For the requirements specified in DIN EN 818-1 Grade 10, however, no details are specified there on the requirements and test methods. Thus, these chains and accessories – depending on the manufacturer – are often different in design and dimensions. A combination of chains from different manufacturers is therefore only possible after consultation and approval .
In April 2006, PAS 1061 (PAS = Publicly Available Specification) was published. PAS 1061 supplements the standards of the DIN EN 818 and series and specifies detailed requirements for short-link, medium-tolerance round steel link chains of grade 10 for use in lifting chains and for general lifting purposes.
The DoComfort product range (chain, hooks and accessories) complies with these specifications, even exceeding them in terms of temperature resistance (400°C instead of 380°C) and has already had the type certificate of quality class 10 issued by the Norddeutsche Metall-Berufsgenossenschaft NMBG since April 2004. As a visible sign this product range is identified by the 10-cornered load capacity tag .
Combination with chains and components from other series is only permitted after prior approval by Dolezych.

Notice:
For safety reasons, components or chains from the DoComfort lifting chain system must not be combined with special grades from other manufacturers or with components or spare parts of other grades. Safety is only guaranteed if all components are “turquoise” and the connecting bolts are “gold” – thus ensuring that they can be assigned to without confusion.
