Real-Time Monitoring of Just-In-Time Rail Conditions



When protecting the largest asset - rail - and reducing fuel are among the top priorities, friction management offers a high return. From increasing operational efficiency through fuel savings and reduced track maintenance, to saving money in rails and ties – friction management plays a major role.

To achieve these benefits, a proven robust application system is required. L.B. Foster’s PROTECTOR Series trackside systems are the industry standard. The PROTECTOR is designed to apply either gauge face grease or revolutionary Friction Modifiers, including KELTRACK and TOR Oils. This innovative system is easy to install and consistently delivers precise, controllable, and reliable application. Backed by the most knowledgeable service team in the industry, we have a solution that can be customized to fit your unique needs.

The heart of the system is the patented double gear pump, which ensures balanced outputs and reduces clogging. This robust gear pump has been reliably applying a wide range of friction control materials for over 5000 systems installed in the field today.

The brain of the system is the Digital Control Box, now available with Remote Performance Monitoring™ technology, which has the capacity to fine-tune the distribution of friction modifiers and lubricants through pump run time and activation intervals. RPM™ is a powerful tool that provides customers the capability to monitor and report uptime, maintenance concerns, and refilling requirements in order to proactively manage the equipment installed on track more efficiently.

Finally, the new generation of applicator bars incorporate L.B. Foster’s patent-pending foam technology. Both our Grease Guide and TOR Foam applicator bars deliver the friction materials exactly where they are required far more efficiently than any other applicator bar in the industry. All bars provide outstanding, even flow because they share our field-proven, balanced port design, along with patented streamlined channels with Teflon® coating, and a wear-resistant distribution blade with V-grooves.

Hydraulic systems offer more simplicity when compared to Mechanical system yet are more affordable than the higher precision Electric Systems. Hydraulic systems minimize the number of moving parts, however with limited degree of application control, and are better suited to shock loading and higher speeds than mechanical systems.

The 761 Hydraulube applies lubricants to the gauge face of the rail and features a gear type pump similar to the Protector ® IV Friction Management System. However the gear pump used on the 761 Hydralube® is powered by a hydraulic motor that is part of a closed loop hydraulic system. The lubricant is available in 400 lb (200kg) and 800 lb (400 kg) capacities. The 761 Hydralube® is most effective in territory where speeds are between 25 and 50 mph (40 to 80 km/h).
