What happens if parts of a tried-and-tested lifting or lashing chain are combined with high-performance textile fibres? The result, according to Dolezych and DSM Dyneema is DoNova, the textine chain, a lightweight and innovative product line for two different application. DoNova PowerLash is a load securing system with a lashing capacity of 10.000 and 16.000 daN and DoNova PowerLift is a lifting chain with a Working Load Limit (WLL) up to 10.500 kilogrammes. Both product lines are the result of intensive cooperation between the two companies.

DSM Dyneema is the inventor and manufacturer of the UHMWPE fibre (Ultra High Molecular Weight PolyEthylene), which is marketed under the brand name DYNEEMA, one of the world's strongest fibres. DYNEEMA offers maximum strength combined with minimum weight and floats on water plus has an extremely high resistance to abrasion and cutting as well as being resistant to moisture, UV light and chemicals.

The fibres are processed by Dolezych, one of the world's leading companies for load lifting and lashing equipment. The multinational family-owned company headquartered in Dortmund, Germany, recognised experience in the development and manufacture of products and owns numerous patents in this field.

The principle of the DoNova chain is both simple and clever: DoNova is manufactured completely from webbing made of DYNEEMA. Several layers of the fabric are wound and sewn to form chain links. This textile chain can be produced in any length and is combined with specially developed chain hooks, high tensile shackles and special tensioner elements. The result is easily comparable with the breaking load and durability of chains made of high-strength steel, but is up to 80% lighter and much more flexible in use, according to the company.

DoNova is offered as a modular system. This allows it to be configured flexibly for the respective purpose of use. The customer selects the chain length, the number of hooks and tensioner elements required and, if necessary, additional shackles for the connection or shortening of chain strands. Both systems - DoNova PowerLash and DoNova PowerLift - are certified for civil applications by DEKRA.
