Tensioning systems

Manual hydraulic tensioner (Dura-Chain XL, Flex and 2XL)*

  • Hydraulic cylinders raise the sliding drive module to take up slack and tension the chain.
  • The manual pressure unit requires only a few pumps of the lever to maintain proper tension.
  • Regulator maintains proper tension under varying loads.

Automatic tensioning system (2XL and Xtreme): The electric power unit automatically maintains perfect tension under all conditions.  The dual tension wheels on Xtreme provide maximum adjustment range for long systems.

*Other tensioner models also available (see chart below).

Chain hardened to resist wear

Chain hardened to resist wear

  • The chain can withstand the steel-on-steel or steel-on-concrete wear that scraper chains are exposed to.
  • The chain can be run in a 2'' x 2'' (5 cm x 5 cm) floor groove, or this compact chain can run on top of the floor without creating cow disturbance.
