About this product
THD DUALINK®-Chains [spec tables 1–2]
THIELE introduced another innovative product to the mining industry by inventing the flat-type chain in 1985. A flat-type chain is a round-link steel chain in which every second link – the vertical link – has flattened legs so that the overall height of the chain can be reduced.
This means that a chain conveyor can be upgraded to the next chain size with matching standard sprocket. THIELE Flat Type links can be produced by either welding and pressing or by forging (DUALINK® chains).
Most of the world’s face conveyors now use Flat Type/DUALINK® Chains from the THD range.
THIELE offers the following types of corrosion protection for THD Flat Type/DUALINK® Chains, depending on underground conditions and storage times:
a) Tectyl dipped (TEC) – for short storage times and good conditions
b) Hot-dip galvanised (TZN) – for longer storage Strength: 345 – 375 HB10 times and corrosive operating conditions

TIP DUALINK®-Chains [spec tables 5–6]
THIELE TIP Chains have been developed for use on high-performance coal faces. By employing special alloyed steel the main
operating parameters of these mining chains have been significantly improved without any loss in impact strength and deformability. As the use of additional alloy constituents means higher material costs the added benefits of TIP Chains only begin to be felt on high-performance faces where the extra expenditure is soon offset by the higher face output and the higher working capabilities of the chains.

High wear resistant crowns (THIELE Super Crown)
Widely used / recommended in BSL-Applications
TSC Chains are not recommended for corrosive
environments – especially in face-conveyor applications – due to the risk of stress corrosion cracking

Very high wear resistant crowns (THIELE Super Duty)
Widely used / recommended in BSL-Applications
TSD Chains are not recommended for wet or aggressive operating conditions as their high strength specifications make them susceptible to stress corrosion cracking
