Advanced Chain Technologies ACTA and ACTE are the agents to supply JDT Longwall Conveyor Chain in Australia and United Kingdom. jdt chain is manufactured in Schwerte Germany with 100 years of manufacturing experience.

Commonly known for its highly optimized material ‘HO’ enables JDT chain to have a higher tensile strength, an increase in hardness and a throughout toughness which decreases the risk of stress corrosion cracking.

HO= Higher strength and toughness compared to standard material

HO=Toughness between 85-100j in both crown and leg

HO= Higher safety and service life due to less wear

Such is the success ‘HO’ material that it is also used to achieve Grade 100 approval for the JDT Enorm Lifting Equipment by the O.H . & S. body in Germany and Lloyds British Offshore. It follows then that the steel that JDT has patented for use in achieving the only Grade 100 lifting chain to European specifications can achieve a higher tensile strength due to its Hardness yet still remain ductile. There is therefore a higher resistance to sprocket ‘Bite’ & interlink wear.

Its resistance to stress corrosion cracking is also verified by the independent testing formed by Aachen University in Germany both in air and in a saline solution where the comparative reductions in cross-sectional area are shown between 1.6758 (basic spec) and JDT 'HO' chain.

It is the combination of both these features in Longwall chains supplied by JDT through ACT that have allowed international acceptance of the steel for Offshore lifting equipment as well.
