The SIM (Suspension Intelligent Management) onboard weighing system from Cleral USA features an embedded computerized load equalizer for tandem and tridem suspensions. The system assesses the weight on each axle and divides it equally by controlling air pressure of the pneumatic auxiliary axle. The auxiliary lift axle is managed by the SIM control, which will raise or lower the pressure of the axle in accordance to the legal load limits. It can be used on both straight-body units and tractor/trailer pairings with either the Reflex (outside mount) or Kiload K2 (cab mounted). 866/901-7372; www.cleral-usa.com.
