Lincoln Industrial has introduced its new QLS 421 Automatic Lubrication System for over-the-road trailers. Designed to reduce the cost of unplanned downtime due to component wear or scheduled manual lubrication of components, the QLS 421 system can supply up to 18 lubrication points with multipurpose grease up to NLGI #2. The system's unique controller card monitors the time a trailer is in use via a motion sensor and delivers the precise amount of lubricant needed, extending the life of brake cams and slack adjusters.
