THIELE Flat Type Chains
THIELE introduced another innovative product to the mining industry by inventing the fat-type chain in
1985. A fat-type chain is a round-link steel chain in which every second link – the vertical link – has fatte-
ned shanks 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 (see DUALINK
chains).

Several years ago THIELE took
things a stage further by
developing its range of Super
Flat Chains that again allow a
chain conveyor to be upgraded
from a Flat Type Chain to the
next Super Flat Chain size, while
retaining the standard sprocket
(see Figure right).
Some dimensions of THIELE’s
range of Flat Type and DUALINK
chains differ to DIN 22255, but
represent long year practice /
experience.
