THIELE Rock Quality (TRQ) TWN 0108
THIELE Rock Quality Chains (TRQ) were specially developed for the conveying of abrasive materials in
stone drifts and roadway drivages. Careful tempering ensures hardness levels of 420 - 450 HB
(1440 - 1540 MPa) over the entire cross-section of the material and a uniform surface hardness at any
point on the chain link.
The TRQ Chain also exhibits a high tensile strength with a fracture stress of 1000 N/mm². The combination
of tensile strength and hardness opens up opportunities for use in diffcult conveying situations where high
tensile loads would rule out the use of surface hardened chains.
TRQ Chains can be operated up to a maximum speed of 0.5 m/s, as the frictional heat generated at
higher chain speeds would result in hardening of the shanks and lead to dangerous crack formation.
the above values apply to chains in ‘natural black’ condition (NSW)
Strength: 420 - 450 HB10
