The Balancer™ B150

The Balancer™ B150 is an electronic lift axle control system, designed to automatically lift and lower the axle based on trailer weight. The B150 senses the weight of the trailer by measuring the fixed axle suspension pressure. The B150 uses customizable control pressures to determine when to lift and lower the axle.

The B150 also provides controls for external valve heater and a max load indicator.


  • Automatically lifts and lowers based on weight
  • Max load indicator
  • Approved for use in the Western Provinces

How it works

Load Control

The load control feature uses pressure measurements made by the built in pressure transducer. When connected to the fixed axle’s suspension, the pressure measurements can be used as a rough estimate of weight. The B150 allows the installer to select the pressures at which the axle should lift and lower. Selection of these pressures is important to ensure the lift axle lowers in time to avoid overweight issues and lifts in time to avoid unwanted wear to the lift axle.

Max Load Indicator

The max load indicator uses the same pressure measurements as the load control. Once the pressure reading is close to the max load pressure, the indicator will flash. It will become solid on, once the pressure exceeds the max pressure setting. The setting is also set by the installer and important for accurate operation.

External Heater

The external heater control will turn on a B150 output wire when the module detects a possibility of freezing. If this wire is connected to an external heater, it can be used to warm a valve and decrease the possibility of a valve freezing.
