MeritorWabco’s trailer lift axle control system

Updated Mar 3, 2015

WheelsUPTruckMeritorWabco has added an automatic trailer lift axle control system to its SmartTrac portfolio of stability control systems to monitor suspension load and manage lift axles on trailers for fleets that reduce load frequently during multiple deliveries. The system is designed to raise or lower the axle automatically based on cargo weight to help reduce fuel costs, tire wear, vehicle downtime and labor and maintenance costs while also increasing wheel-end and brake life.

The system integrates with the company’s trailer roll stability support and anti-lock braking systems and can control multiple trailer lift axles that can be lowered automatically when the trailer is parked; a manual switch can be added to enable drivers to lower an axle.
