ZF has added the Cabin Air Leveling Module (CALM) to its line of cabin dampers designed to help optimize operator comfort in heavy-duty equipment. ZF developed CALM together with Wabco.

  • Contains integrated ride-height control system for the cabin
  • Uses valve to regulate pressure in the air spring depending on cabin height
  • Offers all the advantages of air springs
  • Integrated height-control valve reduces dimensions and simplifies installation, increasing reliability of the ride-height control system and prevents dirt-related failure of the control valve
